Description  translated from Chinese
观众选择型字幕显示的软滚动方法 Select the type of soft rolling method viewers subtitle display

本发明涉及一种观众选择型字幕的软滚动方法,特别是涉及一种把字符和控制码搭载在电视信号上进行发送时,由接收装置接收并根据观众的选择显示字幕的观众选择型字幕的软滚动方法。 The present invention relates to a viewer selectable subtitles soft scrolling method, particularly to a character and control codes to be transmitted when mounted on the television signal, received by the receiving means and the viewer selects to display subtitles according to the selected type of the audience of the subtitle soft rolling method.

现有的电视播放过程中的字幕播放方法分为:在电视信号的有效区间叠加字幕信号,按播放者的选择而观众不能进行选择地显示突发新闻和通知的开式字幕(open caption)方式;在电视信号的非有效区间即垂直消隐区间搭载着字幕信号播放时,能按观众的选择以字幕形式观看电视画面和台词内容的观众选择型字幕(closed caption)方式。 Existing TV broadcast subtitles during playback method is divided into: superimposed caption signal in the effective range of television signals, according to the player's choice and the audience can not be selectively displayed open subtitles breaking news and notifications (open caption) way ; in the non-effective range of television signals that the vertical blanking interval of carrying the caption signal playback, viewers can press Select to view the TV picture and caption in the form of lines of content viewers selective subtitles (closed caption) mode.

观众选择型字幕播放方式是为不使用手语就无法了解画面中的台词内容的听觉障碍者设计的,在美国已于1978年开始这种播放方式,而且它对外语学习也极有帮助。 Select the type of audience subtitle playback mode is not to use sign language you can not understand the contents of the screen in the lines of the design of hearing impairment in the United States in 1978 was the beginning of this playback mode, but it is also very helpful to learn a foreign language.

1994年3月公开的美国专利第5,294,982号,给出了一种适用于罗马文字和音节文字的观众选择型字幕播放方式。 US Patent No. 5,294,982 discloses March 1994, gives one for Roman text and select the type of audience syllable word subtitle playback. 其中,特别对诸如韩国语等音节文字的字幕方式,作了非常详细的说明。 Among them, especially as Korean syllable words such as captions way, made a very detailed description. 所述美国专利中的发明,为了以观众选择型字幕方式播放韩国语,将一个韩国语文字分解成初音、中音、尾音等各音素,并按对应各音素的ASC II码进行发送,接收装置对该ASC II码进行解码,再将其变换成初音、中音、尾音等音素以显示一个韩国语文字。 The US patent invention, in order to select the type of audience broadcast of subtitles in Korean, a Korean word down into the early tone, tenor, tail and other phonemes, press corresponding to each phoneme ASC II code sending and receiving devices the ASC II code is decoded, and then converted into the early tone, tenor, tail and other phonemes to display a Korean text.

这种现有的韩国语文字的观众选择型字幕方式,为显示一个韩国语文字,需要至少使用两至三个字节,所以传送速度和显示速度慢,而且在解码过程中必须组合三至四个字节以寻找一个文字的位置,因此解码处理复杂。 This conventional text viewer selects Korean subtitle type mode, for display of a Korean text, need to use at least two or three bytes, so the slow transmission rate and the display speed, and must be combined in the decoding process three to four bytes to find a location of the text, so the decoding process complicated. 解码处理过程的复杂化将导致解码器成本的上升,这同只对播放机构所必需的编码器相比,数百万计的观众则需要负担高成本的解码器。 Complicated decoding process will lead to increased cost of the decoder, which is only compared to the playing mechanism with the necessary encoder, millions of viewers require costly burden on the decoder.

而且,要想同时显示汉字、韩国语文字、日语,或是同时显示英语、俄语、希腊语,以及显示特殊符号是相当困难的。 Moreover, in order to simultaneously display Chinese, Korean characters, Japanese, or simultaneously display in English, Russian, Greek, and display special symbols is quite difficult.

并且,在显示附加信息的过程中要显示台词信息,然后再显示附加信息的时候,需要使用控制码,所以台词信息和附加信息之间缺乏独立性,为与台词信息的显示模式相区别,控制体系在整体传送效率上更为复杂,而且接收装置如果在动作开始时刻未接收到显示模式控制码,则在接收到下一个控制码之前将不会显示出台词信息。 And, in the process of displaying the additional information to be displayed lines of information, and then displays when additional information is required to use control codes, so the lack of independence of the lines between information and additional information for the lines to distinguish the information display mode, control In the overall system more complex transmission efficiency, and if the receiving device does not receive the operation start time to the display mode control code, then the received information will not be displayed prior to the introduction of the next control word code.

而且,上述的美国专利所公开的发明,是基于美国的电视播放环境、即基于基本上为平原地带的地理环境而开发的,在用于山地占70%以上的韩国的地理环境时,由于接收装置的接收状态不好,所以还存在字幕显示质量变差的缺点。 Moreover, the above-mentioned US patent disclosed invention is based on the American television broadcast environment, which is based essentially on the plains of the geographical environment and development, while more than 70% for the mountainous geography of Korea, since the reception receiving state of the apparatus is not good, so there is the caption display quality deterioration shortcomings.

涉及观众选择型字幕方式、字符播放及接收装置的相关技术,还公开在美国专利5,327,176号,美国专利4,310,854号,美国专利5,347,365号,美国专利5,249,050号,美国专利5,374,960号,美国专利5,315,386号,日本专利公开平6-165,065号,以及日本专利公开平6-165,064号中。 Relates to the viewer selects the subtitle type mode, character playback and receiving device related art is also disclosed in U.S. Patent No. 5,327,176, U.S. Patent No. 4,310,854, U.S. Patent No. 5,347,365, U.S. Patent No. 5,249,050, U.S. Patent No. 5,374,960, U.S. Patent No. 5,315,386, Japan Patent Publication No. 6-165,065 and Japanese Unexamined Patent Publication No. 6-165,064 level.

下面说明用于所述字幕播放和接收系统的字幕信号的具体构成方式。 Manner described below for the specific configuration of the audio playback and the caption signal receiving system.

在韩国,用于播放信号的是525扫描线、60场/秒的M-NTSC制式电视信号,并规定垂直回线消隐期间为,奇数场的第1至第20扫描线,及偶数场的第264至第282扫描线。 In Korea, the playback signal is used for 525 scan lines, M-NTSC system television signal of 60 fields / sec, and the predetermined period is a vertical retrace blanking lines, the first to the scanning lines 20 odd-numbered fields and even fields 264 to 282 scan lines.

相关组织尚未提供有关垂直线消隐期间的信号使用的标准,但可将ITU-R建议Rec473-2和美国的FCC报告和指令(Report and Order)83-120中给出的内容作为参考。 Relevant standards organization has not provided during the vertical blanking signal line use, but can be Rec473-2 ITU-R Recommendations and US FCC Report and Order (Report and Order) content 83-120 given as a reference.

为了传送字幕数据,字幕信号可以使用垂直回归线消隐期间的第10至第20行扫描线或有源视频区间的第21、第262、第525扫描线中的某一条。 In order to transmit data subtitle, caption signal can use the vertical blanking interval of the regression line 21, 262, 525 scan lines Articles 10 to 20 scan lines or active video during a certain interval of one. 为增加数据传送量,或是为了其它的目的,也可以使用一条以上的扫描线。 To increase the amount of data transfer, or for other purposes, may be used more than one scan line.

字幕数据的传送比特率必须为447443.125bps+125bps,长时间变化率的最大值应在196以内(0.0125bps),字幕数据信号仅用于彩色电视信号的传送,传送比特率设定为色度副载波频率fsc(357954510Hz)的1/8,并且应该与彩色脉冲频率同步。 Transmission bit rate of the subtitle data must 447443.125bps + 125bps, the maximum time rate of change should be within 196 (0.0125bps), only the caption data signal for transmitting color television signals, the transmission bit rate is set chromaticity subcarrier frequency fsc (3579545 10Hz) 1/8, and should be synchronized with the color burst frequency. 所述色度副载波最好具有扫描线与扫描线之间的连续相位。 Preferably the chrominance subcarrier and having a continuous phase scan lines between scan lines. 当由于画面编辑等原因而使色度副载波的相位不连续时,最低限度也应使该扫描线与彩色脉冲的位相同步。 When the screen editing, etc. Since the reason the chrominance subcarrier phase is not continuous, but also should make the minimum scan line with the color burst is phase synchronized.

数据调制方式使用两相相位调制(BPSK;Binary Phase Shift Keying,下面称为BPSK),也叫相位反转调制(PRK;Phase Reversal Keying,下面称为PRK)。 Data using a two-phase modulation phase modulation (BPSK; Binary Phase Shift Keying, hereinafter referred to as BPSK), also known as phase inversion modulation (PRK; Phase Reversal Keying, hereinafter referred to as PRK). 对应逻辑值为′1′的是用相位为0度具fsc/8(447.443kHz)的频率的一个周期的正弦波表示,对应逻辑值′0′的是用相位为180度具有fsc/8(447.443kHz)的频率的一个周期的正弦波表示。 Corresponds to a logical value '1' is the phase of 0 degrees with fsc / 8 (447.443kHz) of one cycle of a sine wave frequency that corresponds to a logical value '0' is used as a phase of 180 degrees with fsc / 8 ( A cycle 447.443kHz) frequency sine wave representation. 相位抖动的最大范围是10度。 The maximum range of the phase jitter is 10 degrees. 最佳信号波形根据电视信道的频谱特性而改变,因此在以后会规定的。 Best signal waveform according to the spectral characteristics of the television channel is changed, so in the future will be predetermined. 然而,由于根据基本的频带限制频率,BPS波形在产生逻辑值变化的区域可能会产生很强的畸变现象,所以将经过具有3.5MHz阻断频率的两次巴特沃思(Butterworth)滤波器相位修正后的波形用于播放。 However, due to restrictions in accordance with the basic frequency band, BPS waveform generation logic value change area may produce a strong distortion phenomenon, so will go through with a 3.5MHz frequency twice blocked Butterworth (Butterworth) filter phase correction After the waveforms for playback. 所使用的巴特沃思滤波器的脉冲响应式由下式(1)给出:|H(f)|=11+(f/fc)4]]>(其中,fc=3.5MHz)韩国无线局检查项目中的I-7(电视播放局)项目4(字符多重播送)“na”项(数据线的叠加位置和字符信号的振幅)中,定义了检查方法及其根据。 Used Butterworth filter impulse response of formula by the following formula (1) gives: | H (f) | = 11 + (f / fc) 4]]> (where, fc = 3.5MHz) wireless local Korea Check the project's I-7 (TV station) Item 4 (a character multiple broadcast) "na" item (amplitude superimposed on the location and character of the data signal lines), the definition of the inspection methods and in accordance with. 由于字幕信号的波形不是NRZ波形而是纯粹的正弦波,所以不一定要采用上述标准,但根据像韩国山地占70%以上的地域特性,为了扩大可接收地域,其正弦波的最大值为905IRE。 NRZ waveform waveform is not because of subtitles but pure sine wave signal, so do not have to adopt these standards, but according to South Korean mountain like more than 70% of the geographical features, in order to expand the area can receive a maximum value of the sine wave of 90 5IRE. 虽然确定了正常数据信号的最大振幅,但由滤波器带通频率特性等因素而含有脉冲尖峰,因此脉冲尖峰的最大绝对值定为5IRE。 While determining the maximum amplitude of the normal data signal, but by a factor of a band-pass filter comprises a frequency characteristic like spikes, so that the maximum absolute value of the peak of the pulse as 5IRE.

下面,由图3可知,字幕信号的数据线由6周期的位时钟同步信号302、字起始信号304和18位数据列306构成的。 Next, Figure 3 shows, the caption signal data lines by 6 cycles bit clock synchronization signal 302, word start signal 304 and the 18-bit data column 306 formed.

位时钟同步信号302是一个6周期的正弦波,可从字幕解码部中提取出该信号,并在判断18位数据的位周期时使用,其频率为fsc/4(894.886KHz)。 Bit synchronization clock signal 302 is a 6-cycle sine wave, can be extracted from the caption decoder section for the signal, and when it is determined that the use of 18-bit data bit period, the frequency of fsc / 4 (894.886KHz). 当该扫描线的色度副载波的相位为0度时,从与水平同步信号的下降沿中间点(OH)距离9.5μsec(色同步信号34周期)处开始,而当该扫描线的色度副载波的相位为180度时,则从与水平同步信号的下降沿中间点(OH)距离9.64μsec(色同步信号34.5周期)处开始。 When the phase of the chrominance subcarrier of the scanning line is 0 degree, from the intermediate point and the falling edge of the horizontal synchronizing signal (OH) from 9.5μsec (burst signal 34 cycles) at the beginning, and when the scan line chrominance phase subcarriers is 180 degrees, from the falling edge of the intermediate point with the horizontal synchronizing signal (OH) from 9.64μsec (34.5 color burst signal period) starts. 由于该信号是与该扫描线的色同步信号是同步的,所以也可从色同步信号中提取位时钟同步信号。 Since the signal is synchronized, so it can be extracted from the bit clock synchronization signal and the color burst signal synchronization signal of the scan line.

字开始信号304是具有fsc/16(223.722kHz)的频率及180度相位的正弦波信号的一个周期,它的作用是表示18位数据组的开始。 Word 304 is a cycle start signal frequency and 180 degrees out of phase sine wave signal having the fsc / 16 (223.722kHz), its role is to indicate the start of the 18-bit data set.

数据列306由18位构成,比特率为fsc/8(447.443kHz),并由BPSK方式进行调制。 306 by 18 columns of data structure, bit rate fsc / 8 (447.443kHz), by way of BPSK modulation.

如图4A、4B所示,数据组由字符单元的奇偶校验位p、字幕/附加信息标志(C/T)和码值三部分构成。 FIG. 4A, 4B, the data set is composed of parity bits p, subtitles / additional information flag (C / T) and a code value of the character cell of three parts. D0~D8被称为低位字,D9~D16被称为高位字。 D0 ~ D8 is called the low word, D9 ~ D16 is known as the high word. D17是关于D0~D17的偶数奇偶校验位。 D17 is about D0 ~ D17 of the even parity bit. 该奇偶检验位首先检测传送中的误码。 The parity bit is first detected transmission error. D7和D16为字幕/附加信息标志,当是字幕时为0,是附加信息时为1,而且D7和D16的值必须保持一致。 D7 and D16 for subtitles / additional information signs, when the subtitle is 0, when the additional information is 1, and the value of D7 and D16 must be consistent. 该标志可用于保证字符单元的优先顺序位。 This flag can be used to prioritize bit guarantee character unit. D0~D6和D9~D15均表示码值。 D0 ~ D6 and D9 ~ D15 have said code value. 在D5、D6、D14、D15的码值为“0”时则被分析为控制码,否则被分析作为字符码。 In D5, D6, D14, D15 of the code is "0", were analyzed as control code, otherwise it is analyzed as the character code.

图5中,7位控制码的D1、D2、D3、D9、D10、D11、D12为控制码数据位,D0、D4、D8、D13是关于控制码数据位的奇偶校验位。 Figure 5, D1 7-bit control code, D2, D3, D9, D10, D11, D12 to the control code data bits, D0, D4, D8, D13 on the control code data bits are parity bits. 低位字的3位码值用于指定五种功能,这五种功能为色指定功能,字符属性及上滚动功能,显示方法及下滚动功能,位置移动功能,行列位置指定功能。 The lower word is used to specify the value of 3 yards five functions, which features five functions for the specified color, character attributes and the scroll function, display method, and scroll functions, the location of mobile functionality, the ranks of the location specified functions. 控制码的高位字中的4位码值,指定了各功能的16个子功能。 Control code in the high word of four yards, specifying 16 sub-functions of each function. 在这儿,D0是关于D1、D2、D3、D4的奇偶校验位,D4是关于D1、D2、D10、D11的奇偶校验位,D13是关于D9、D10、D11、D12的奇偶校验位。 Here, D0 is about D1, D2, D3, D4 of the parity bit, D4 is about D1, D2, D10, D11 of the parity bit, D13 is about D9, D10, D11, D12 parity .

而且,为确保数据的安全接收而连续传送两次控制码,每隔4秒钟周期性地传送横向书写/竖向书写指定码和行列位置指定码。 Moreover, in order to ensure the safety of receiving data and control code continuously transmitted twice every 4 seconds periodically transmit written horizontally / vertically writing code and specify the location of the specified code ranks. 对控制码的具体说明在后面进行。 Control codes for specific instructions later in.

如图6A~6T所示,字符码的低位字中的D0~D6和高位字的D9~D15,共同表示KSC5601码的数据位。 As shown in Figure 6A ~ 6T, low word character code in the D0 ~ D6 and the high word of D9 ~ D15, together represent data bits KSC5601 codes. D8是关于D0~D7的偶数奇偶校验位。 D0 ~ D7 D8 is about the even parity bit.

由于本发明完全没使用ABCII码,所以D0~D6这7位对应于KSC5601的低位字节中的除MSB以外的7位,而D9~D15对应于高位字节中的除MSB以外的7位。 Due to the use of the present invention is not entirely ABCII code, so D0 ~ D6 7 Bits These 7 except MSB corresponds to the low byte KSC5601 outside, and D9 ~ D15 corresponds to 7 in addition to the high byte MSB outside. 如图6A~6T所示的韩国语文字完成型码(KSC5601)中,按a1~a2行(特殊字符)、a3行(数字和英文)、a4行(韩国语文字中由尾音构成的子音)、a5行(希腊文)、aa~ab行(日文假名)、ac行(俄文)、b0~c8行(韩国语文字)、ca~fd行(汉字)使用。 Figure Korean word completion type code (KSC5601) shown 6A ~ 6T, press a1 ~ a2 line (special characters), a3 line (numbers and English), a4 line (Korean text composed by the tail consonants) , a5 line (Greek), aa ~ ab line (Japanese kana), ac line (in Russian), b0 ~ c8 line (Korean text), ca ~ fd line (characters) to use. 字符码对应于一个字符发送只一次。 Character code corresponding to a character is sent only once.

如上所述,韩国语文字字幕可利用每一场中的任一行进行发送,限定在一个场中的一个以上的传送行被定义为信道。 As mentioned above, the Korean language text captions can be used in every game to send any line, limited to a field of more than one transmission line is defined as a channel. NTSC制电视以隔行扫描方式构成两个场,因此使用两个信道。 NTSC television system constituted two interlaced fields, and therefore the use of two channels. 也就是说,可使用例如多路声音的双语字幕,其中韩国语文字专用字幕应使用奇数场信道,而其它的外语专用的字幕应使用偶数场信道。 That is, for example, bilingual subtitles may be multiplexed using the sound, in which Korean text subtitles dedicated channel odd fields should be used, while other foreign language subtitles dedicated channels should be used even field. 每个信道传送的控制码具有相同的码组,所有字符码均包含在KSC5601中。 Each control code channels transmitted with the same code group, all character codes are included in KSC5601 in.

由字幕用信道传送的信息有两种,对应于其不同种类控制码的含义和显示方法也不相同。 There are two subtitle channel by the information transmitted, corresponding to the different types of control code and a display method is not the same meaning. 其中的一种为与播放中的图像信号相关的字幕,而另一种为与画面上看到的播放内容不相关的附加信息(TEXT)。 One of which is the playback image signal associated with the subtitle, and the other to see and play the content on the screen additional information not relevant (TEXT).

在数据组结构的低位字和高位字中,若字幕/附加信息标志的值全为0,码值则不论是控制码还是字符码,均认为是用于显示字幕的。 In the low-order word data set structures and high word, if the value of the subtitle / Additional information signs are all 0, code value is either a control code or character codes are considered to be used to display subtitles. 这时,它一边只遮住画面的一部分,一边以字幕形式显示出与音频信号相一致的台词。 In this case, while it is only a cover portion of the screen, while showing a caption format consistent with the audio signal lines.

为了同时只使用2~5行的字幕,且显示连续的台词,可采用将该区域滚动的方式或消去后再重写的方法。 In order to use only 2 to 5 lines of subtitles and display continuous lines, the area can be scrolled or eliminated after the overridden method.

在仅用一条信道进行传送时,可混用多种文字,或者将其作为韩国语文字专用或外语专用信道使用,而当采用两条信道进行发送时,则可区分为韩国语文字专用信道和外语专用信道使用。 When only one channel for transmission can be a mix of text, or as a special character in Korean or foreign dedicated channels to use, but when using two channels for transmission, and Korean characters can be divided into dedicated channels and foreign language dedicated channel used.

由于所述台词字幕应与音频信息尽可能一致,所以在两个字符单元的信道占用中,该台词字幕比附加信息具有更高的优先权。 Because the lines of subtitles should be as consistent as possible with the audio information, it occupies two characters in the channel unit, the subtitle lines than the additional information has a higher priority.

在数据组结构的低字位和高字位中,若字幕/附加信息标志的值全为1,码值则不论是控制码还是字符码,均认为是用于显示附加信息的。 In the low and high word bit bit data word group structure, if the value of the subtitle / additional information for a full mark, code value is either a control code or character code, are considered to be used to display additional information. 附加信息显示与播放内容无关,象计算机通信那样在整个画面上显示字符信息。 The additional information display and playback, regardless of content, is displayed as character information on the entire screen as computer communications. 由于显示在整个画面上,所以不使用滚动功能。 Since the display on the entire screen, a scroll function is not used.

在使用两条信道传送时,附加信息不必象台词信息那样进行分离,只要在信道中未载有台词信息,则附加信息就可以在任何时候占据信道。 When using two channel carries, as additional information need not be isolated, as the speech information, as long as the channel does not contain speech information, the additional information may occupy the channel at any time. 在应传送台词字幕时立即让出信道的占有权,而在台词字幕传递结束后再占据信道。 When the transmission lines should be let out immediately subtitle channel tenure, but at the end of the speech delivered before the subtitles occupy channels.

下面,对接收机采用字幕横向书写方式时的开显示进行说明。 Now, the receiver uses the open display captions written transverse mode will be described.

如图7所示,字幕区域702是指整个有效画面范围中的可显示台词字幕和附加信息的最大区域。 As shown in Figure 7, the subtitle area 702 refers to the entire range of the effective picture area of the maximum can be displayed subtitle lines and the additional information. 在以NTSC制电视信号的一个场单位中,字幕区域702从扫描行41开始至扫描行240结束,因此每个场具有相当于200条的电视扫描线高度。 In a field unit to the NTSC television signal, the subtitle area 702 starts from the scan line 41 to the end of the scan line 240, so that each field have the equivalent of 200 of the television scanning line height. 在整个字幕区域显示十行字符。 Display ten lines of characters in the entire caption area. 字幕区域的宽度定为有效扫描线宽度(52.6μsec)的80~85%左右。 The width of the caption region is set at the effective scanning line width (52.6μsec) of about 80 to 85%. 因此,整个的字符行的横向长度为有效扫描线宽度的80~85%。 Thus, the entire lateral length of the character lines 80 to 85% of the effective scanning line width.

韩国语文字、英文、汉字的显示单元,总共由纵向20个位图构成,所以为了容易显示,韩国语文字、英文、汉字构成的一个字符行(Row)由20个电视扫描线构成。 Korean characters, English characters a display unit composed of a total of 20 longitudinal bitmap, so in order to easily display, Korean characters, English, a character row (Row) composed of characters by 20 TV lines constituted.

在每一行中,可横向显示的韩国语文字和日文假名的最大数目定为18个。 In each row, the maximum number of horizontal display of Korean and Japanese kana characters set at 18. 由于一个英文字母的宽度为一个韩国语文字的宽度的一半,所以每一行中可显示的英文字母的最大数目为36个。 Due to the width of one letter for half the width of a Korean text, the maximum number that can be displayed in each line is 36 letters of the alphabet. 罗马语系的文字、阿拉伯数字、文章符号等的显示方式与英文相同。 Roman language text, Arabic numerals, symbols, etc. display articles in English the same way.

一个汉字的宽度与一个韩国语文字的宽度相同,所以每一行中可显示的汉字的最大数目为18个。 The width of a character and a Korean word of the same width, so the maximum number of characters in each line can be displayed for 18.

可混合显示由KSC5601码支持的所有字符。 Display all characters can be mixed by KSC5601 code supports. 当混合使用时每一行可显示的最大字数为18至36个。 The maximum number of words when used in combination can be displayed for each line 18-36.

如图8A~8C所示,在画面上显示字符时,不考虑画面上字符之间的间隙的、仅一个字符自身占据的区域称为字符单元(804,814,824),而将包括文字周围的间隙在内的一个字符所占据的区域称为显示单元(802,812,822)。 As shown in FIG. 8A ~ 8C, when the characters displayed on the screen, irrespective of the gap between the characters on the screen, only one character region occupied by itself is called a character unit (804,814,824), and the surrounding text a character region including the gap occupied called a display unit (802,812,822).

在接收机中,显示在画面上的一个音节的韩国语文字的字符单元804,具有横向16、纵向16的位图格式。 In the receiver, displayed on the screen of a syllable of Korean text characters 804, 16 having a transverse, longitudinal 16 bitmap format. 从而,要进入字符单元的韩国语文字从存储有横向16、纵向16的位图字体的ROM中读出。 Thus, to enter text in Korean characters unit laterally from 16 stores, 16 vertical bitmap font ROM read out.

在图8A中,接收机的考虑字符之间间隙的一个音节韩国语文字的显示单元802,具有横向18、纵向20的位图格式。 In Figure 8A, the gap between a syllable character receiver consider the Korean text display unit 802, has a lateral 18, 20 longitudinal bitmap format. 这是因为在韩国语文字的字符单元804的上、左、右三个方向上分别设有一行的间隙,而在下方设有一行间隙的同时,还设置有2行间隙,以用于设定下划线区域806的情况。 This is because in the Korean text character cell 804, left, and right directions, respectively, with three gap line, and a line provided below the gap, it is also provided with two rows gap, for setting case underlined region 806.

由接收机显示的日文假名的格式与韩国语文字相同。 Japanese Kana format displayed by the receiver with the same Korean text.

如图8B所示,显示在接收机画面上的汉字的字符单元814,具有横向17、纵向19的位图格式。 8B, the screen is displayed on the receiver unit Kanji character 814, has a lateral 17, 19 longitudinal bitmap format. 汉字字符单元814的尺寸格式是暂时的,在以后可以考虑字体ROM和接收机电路上的条件确定一个不同尺寸(横向16、纵向16)的字符单元。 Kanji character cell size format 814 is temporary, conditions can be considered in the future font ROM and receiver circuit is determined on a different size (lateral 16 and vertical 16) of the character cell.

接收机的考虑了字符之间间隙的汉字显示单元812,具有横向18、纵向20的位图格式。 The receiver takes into account the gap between kanji character display unit 812, has a lateral 18, 20 vertical bitmap format. 这是因为在汉字的字符单元814的右方和下方分别设有一行的间隙,并且与韩国语文字或英文不同,它不具有对应于一个字的下划线区域。 This is because the kanji character unit are provided to the right and below the 814 line clearance, and with Korean or English text, it does not have a word corresponds to underscore area.

因此,汉字显示单元812的宽度和高度均与一个音节的韩国语文字显示单元802的宽度和高度相同,所以一个汉字与一个韩国语文字具有相同的尺寸。 Therefore, character display unit 812 of the width and height were associated with a syllable in Korean text display unit 802 of the same width and height, so a character with a Korean word has the same dimensions.

如图8(C)所示,显示在接收机画面上的英文字母的字符单元824,具有横向8、纵向14的位图格式。 FIG. 8 (C), the display on the screen of the receiver unit 824 English alphabet characters, having a transverse 8, 14 of the longitudinal bitmap format.

在接收机中,考虑了文字之间间隙的英文字母的显示单元822,具有横向9、纵向20的位图格式。 In the receiver, consider a gap between the letters of the text display unit 822, has a lateral 9, 20 longitudinal bitmap format. 这是由于在英文字母的字符单元824的上方设置两行间隙而在右方设置一行间隙的缘故,在下方设有两行间隙的同时,考虑到要设置下划线区域826还设置了两行的空余区域。 This is due to set the gap at the top two lines of the English alphabet characters unit 824 and set a line clearance on the right reason, has two lines at the bottom of the gap at the same time, taking into account the region to set underline spare 826 also set two lines area.

因此,英文字母显示单元822的宽度为一个音节的韩国语文字显示单元802宽度的0.5倍,两者的高度相同,所以一个韩国语文字具有与两个英文字母相当的尺寸。 Therefore, the width of the letters display unit 822 is a syllable in Korean text display 0.5 times the width of the unit 802, both the same height, so a Korean word has two letters considerable size.

英文以外的罗马语系的其它语言和阿拉伯数字,以及包含在单词之间的空格等的文章符号,在接收机上的显示格式与英文相同。 A language other than English, and Arabic numerals Roman languages, as well as the space between the words contained in the articles and other symbols on the receiver's display format and the same in English.

在接收机中的显示单元内的字符显示处理方式,按'底色指定'控制码进行不透明底处理或外轮廓线处理,并可将不透明底转换为半透明底显示。 Character display unit in the receiver within the display processing mode, press 'background specified' control code opaque bottom outer contour line processing or handling, and can be converted into a translucent opaque bottom end display.

接收机在用不透明底处理方式显示字符时,将各行中的第一个字符的前部和最后一个字符的后部处理成具有一个音节的韩国语文字字符尺寸的不透明底,使读出更为方便。 The receiver at the bottom with an opaque treatment display characters, the rear portion of the front of each row of the first character and the last character processed with a Korean syllable opaque bottom text character size, the read out more convenience.

下面对图5所示的控制码进行详细的说明。 Next, the control code shown in Figure 5 is described in detail.

控制码由两个9位字组合而成,低位字包括用于功能分类的D1、D2、D3位,而高位字包括用于选择分类后功能中的某一个子功能的D9、D10、D11、D12位。 Control code combination of two words from nine, including low word for the functional classification of D1, D2, D3 position, while the upper word includes functions for selecting a classification after a certain sub-function of D9, D10, D11, D12 bits.

控制码可根据其功能分类为颜色指定、属性指定、显示指定、滚动、光标移动、行位置和列位置指定控制码。 Control code can be classified according to their function to specify the color attributes specified display specified, scrolling, cursor movement, the row and column position of the specified position control codes.

颜色指定控制码是为改变被传送的字符数据的前景和底颜色而传送的控制码。 Color designation control code is a control code for changing the foreground character data to be transmitted and a background color and transmission. 因此,在要改变传送的字符的前景和底颜色的时候,可以在传送色指定码后再发送字符。 Therefore, in the foreground to change the character of the transmission and the background color, they can specify the number of characters before sending the transmission color. 接收机根据最新接收到的颜色指定控制码确定其前景和底颜色。 Specify the control code receiver to determine its prospects and background color according to the latest received color. 而且,前景和底的颜色可以同时或独立地进行改变。 Moreover, prospects and bottom colors can be changed simultaneously or independently. 颜色可以指定为黑色(Black)、红色(Red)、深红色(Magenta)、兰色(Blue)、青色(Cyan)、绿色(Green)、黄色(Yellow)、白色(White)等。 Colors can be specified as black (Black), red (Red), magenta (Magenta), blue (Blue), cyan (Cyan), green (Green), yellow (Yellow), White (White) and the like. 底色为透明色时,可在显示单元中除字符以外的其余部分看到正在播放的节目图像,且用与字符颜色不同的颜色对各字符进行了外轮廓线处理。 When the background color is transparent, in the remaining part of the display unit other than the character image to see the live program, and with a different color and a character color for each character of the outer contour line processing.

字符属性控制码是为改变字符数据的属性而传送的控制码。 Character attribute control code is a control code to change the attributes of character data and transfer. 因此,要改变传送的字符属性时,可以先传送属性指定控制码,然后再传送字符码。 Therefore, when you want to change the character of the property transfer, you can transfer property to specify the control code, and then transfer the character code. 它可以进行正常、下划线、闪烁、反白显示等指定。 It can be normal, underline, blinking, anti-white display is specified. 由于正常、下划线、闪烁、反白显示等均可独立地作用,故可以在一次同时使用上述的全部属性。 Due to normal, underline, blink, reverse video, etc. can act independently, so you can use all the properties described above, while in one.

各属性指定控制码的功能如下所述:○下划线:在显示出的各字符的正下方显示出下划线。 Each attribute specifies the control function code is as follows: ○ Underline: out immediately below each character display shows underlined.

○闪烁:闪烁显示出的字符。 ○ Flashing: Flashing shows character. 不闪烁先前显示的部分,只闪烁以后显示的部分,闪烁周期可随接收机的具体实现方式而有所不同。 Not previously displayed flashing section, part of the cycle after flashing flashing display can only vary with the specific implementation of the receiver.

○反白显示:改变接收机目前使用的前景颜色和底颜色。 ○ Highlight: change the foreground color receivers currently in use, and background color.

○正常:恢复所有被指定的属性,按缺省时(default)属性显示字符。 ○ Normal: restore all the attributes specified, press the default (default) attribute display characters.

显示方法控制码是为控制开显示方式而传送的控制码,它用于指定开显示、关显示、接收存储、横向书写、竖向书写等。 Display method and control codes are transmitted for controlling the opening mode of the display control code, which is used to specify start and display, display OFF, the reception memory, written laterally, vertical writing and the like.

○开显示:将接收到的字符数据直接显示在画面上(上滚动、下滚动时),并根据'接收存储′控制码将存储的数据显示在画面上(弹出模式时)。 ○ open the display: the received character data displayed directly (scroll, when scroll) on the screen, and according to 'receive memory' control code stored data displayed on the screen (pop-up mode).

○接收存储:存储在开显示之前接收到的字符和控制码。 ○ receiving Storage: Before opening the display received characters and control codes.

○横向书写:在不通过位置变更控制码而将连续接收到的字符码连续地显示在画面上时,使下一个字符位置向当前字符的右侧移动。 ○ written laterally: when continuously received and the character code is continuously displayed on the screen without changing the position of the control code, so that the next character position to the right of the current character.

○竖向书写:在不通过位置变更控制码而将连续接收到的字符码连续地显示在画面上时,使下一个字符位置向当前字符的下侧移动。 ○ vertical writing: passing position without changing the continuous control codes received character codes successively displayed at the screen, so that the next character position to the lower side of the current character.

滚动控制码是用于在选定字母区域的一定部分后进行画面滚动的控制码,该滚动控制码包括'2~5行上滚动′和'2~5行下滚动'。 Scroll control code is used after a certain portion of a letter area selected for the screen scroll control code, the control code includes a rolling 'roll on the line 2-5' and '2-5 lower line scroll'.

○2~5行上滚动:是使由包含当前字符显示位置(光标位置)的上边2~5行构成的窗口内容上滚动一行并显示的控制码,随着滚动而消除选定窗口中的最上一行,同时使最下一行由最新解码的字符代替。 Roll on ○ 2 ~ 5 lines: is that rolling by containing the current character display position (cursor position) the upper window contents composed of 2 to 5 rows and row display control code, along with the elimination of the scrolling of the selected window line, while the bottom line is replaced by the latest decoded characters. 在使用该控制码时,不需要其它的APDR(向下一行起始字符位置移动)码,指定窗口外部的所有字符从画面上消失。 When using the control code, no other APDR (down one line starting character position) code, all the characters outside the specified window disappears from the screen.

○2~5行下滚动:是使由包含当前字符显示位置(光标位置)的上边2~5行构成的窗口内容下滚动一行并显示的控制码,随着滚动而消除选定窗口中的最下一行,同时使最上一行中由最新解码的字符代替。 Under ○ 2 ~ 5 line scroll: to make the current character display position by comprising (cursor position) the upper window contents composed of 2 to 5 rows and displays scrolled one under control code, as a selected window scroll eliminate most The next line, while the top line in place by the latest decoded characters. 在使用该控制码时,不需要其它的APUR(向上一行起始字符位置移动)码,指定窗口外部的所有字符从画面上消失。 When using the control code, no other APUR (up one line starting character position) code, all the characters outside the specified window disappears from the screen.

位置移动控制码是关于字符显示位置的方向移动的控制码。 Position control code is a character display position on the direction of movement of the control code.

○APF(Active Position Forword,有效位置向前):在横向书写时沿字符书写的主要行进方向(右侧)移动一个韩国语文字宽度的一半(一个英文字母宽度)。 ○ APF (Active Position Forword, effective forward position): in the transverse direction of characters written in the writing main traveling direction (right side) to move half of the width of a Korean character (letter of the width). 在竖向书写时沿主要行进方向(下侧)移动一个韩国语文字的高度。 When the vertical height of a Korean writing move along the main text of the traveling direction (lower side).

○APDR(Active Position Down Return,有效位置下转):在横向书写时移动到当前字符显示位置正下行的最左侧字符位置(第一列位置)。 ○ APDR (Active Position Down Return, the next valid position switch): When a lateral move to the leftmost character position of writing the current character display position being downstream (the first column position). 在竖向书写时移动到当前字符显示位置正左侧列最上面的字符位置(第一行位置)。 When writing to move the vertical position of the current character is displayed in the left column are the top character position (first row position). 沿主要行进方向(下侧)移动一个韩国语文字字符的高度。 Along the main traveling direction (lower side) of a highly mobile Korean text characters.

○APUR(Active Position Up Return,有效位置上转):在横向书写时移动到当前字符显示位置正上行的最左侧字符位置(第一列位置)。 ○ APUR (Active Position Up Return, effective position switch): When a lateral move to write the current character display the leftmost character position (first column position) are upward position. 在竖向书写时移动到当前字符正右侧列的最上面的字符位置(第一行位置)。 Is moved to the current character position (first row position) uppermost right-hand column of the character is written when the vertical.

○3~6字APF:在横向书写时进行约3~6个英文字母宽度的APF。 ○ 3 ~ 6 words APF: about 3 to about six letters of the alphabet in the transverse width of the APF writing. 在竖向书写时进行约3~6个英文字母高度的APF。 For about three to six letters of the alphabet when the vertical height of the APF in writing.

下面举例说明位置移动控制的若干例外情况。 The following examples illustrate some exceptions position control. 当横向书写时一直到行的最右侧字符位置(第18列位置)也有字符显示时,若在没有APDR、APUR、APB、2~5行上滚动、2~5行下滚动等与适当位置移动相关的控制而接收字符码时,则可以不改变行,而移动到该行的最左侧位置(第一列位置)后显示字符。 When the appropriate position has been written laterally to the row of the rightmost character position (18 position) when there are character display, if no APDR, APUR, APB, roll on the line 2-5, at 2 to 5 rows scrolling Mobile related control while receiving the character code, you can not change the line, but moved to the leftmost position (first column position) of the line after the character. 只是,这时接收到的若是空格码,则将忽略,直至接收到非空格字符码为止。 But, then the received code if the space is ignored until it receives a non-space character code so far. 当竖向书写中,如果直到列的最下面的字符位置(第10行位置)也有字符显示时,若在没有APDR、APUR、APB、2~5行上滚动、2~5行下滚动等与适当位置移动相关的控制码而接收到字符码时,则可以不改变列,而移动到该列的最上方位置(第一行位置)后显示字符。 When vertical writing, if the bottom of the character positions (line 10 position) until the column is also a character is displayed, if no APDR, APUR, APB, the 2-5 line scroll, scroll down and 2 to 5 lines, etc. When the proper position related control codes received character code, the column may not be changed, and moves to the uppermost position (the first row position) of the column after the display character. 只是,这时接收到的若是空格码,则将其忽略,直至接收到非空格字符码为止。 But, this time received if space code, it will be ignored until it receives a non-space character code so far.

根据开显示方式的控制码传送方式如下面所述。 Based on open display control code transmission mode as described below.

弹出模式时的控制码传送顺序为:接收存储+(其它的控制码)+字符列+(其它控制码)+......+关显示+开显示+接收存储+(其它控制码)+字符列+(其它控制码)+......+关显示+开显示+......。 Control code transmission order eject mode for: receiving storage + (other control codes) + character columns + (other control code) + ...... + Off Display + open display + storage + receive (other control codes) + character column + (other control code) + ...... + Off Display + open display + ....... 为了使观众正常观看以弹出模式显示在屏幕上的字符信息,在发送部发送显示擦除控制码之前,需要适当的延迟时间。 In order to give the audience a normal viewing mode to display a pop-up message on the screen of the characters in the display before erasing transmitter transmits a control code requires appropriate delay.

上滚动时的控制码传送顺序为:开显示+(其它控制码)+字符列+(其它控制码)+字符列+(2~5行上滚动码)+开显示+(其它控制码)+字符列+(其它控制码)+字符列+(2~5行上滚动码)+……。 Transmission order control code on the scroll is: open the display + (other control codes) + character columns + (other control codes) + character columns + (2-5 on the line rolling code) + open display + (other control code) + character column + (other control codes) + character columns + (2 to 5 lines rolling code) + ....... 每当接收到2~5行上滚动控制码时,应该用透明颜色擦除规定的窗口外部区域。 Whenever receiving the 2-5 line scrolling control codes, should erase the specified window with a transparent color outside the area.

下滚动时的控制码传送顺序为:开显示+(其它控制码)+字符列+(其它控制码)+字符列+(2~5行下滚动码)+开显示+(其它控制码)+字符列+(其它控制码)+字符列+(2~5行下滚动码)+......。 Control code transmission order to scroll when: On display + (other control codes) + character columns + (other control codes) + character columns + (2-5 lines under rolling code) + open display + (other control code) + character column + (other control code) + character columns + (2-5 lines under rolling code) + ....... 每当接收到2~5行下滚动控制码时,应该用透明颜色擦除规定的窗口外部区域。 Whenever receiving the 2-5 line scroll control code, it should be outside the window with a transparent color erasure area specified.

由电视台指定软滚动的情况下,在指定所述上滚动和下滚动的软滚动模式时,是在上滚动或下滚动控制码的后面插入软滚动控制码。 Specified by the television soft scrolling, scroll and scroll and scroll down the soft mode in the upper designated, is in the scroll up or down to scroll back control code inserted into a soft roll control codes.

下面说明竖向书写时的控制码的处理方式。 The following describes the processing mode when writing the vertical control code.

接收机在解码出竖向书写控制码时,可将画面上显示的韩国语文字符的行进方向切换为列方向。 When the receiver decodes the control code of vertical writing, the traveling direction can be displayed on the screen is switched to the Korean language character column direction.

竖向书写主要用于在播放内容中存在字幕的时候。 Vertical writing mainly for the presence of subtitles when playing content. 竖向书写时的字符单元的结构,不需要与横向书写时的各字符的相应字符单元相同。 The vertical structure of a character when writing unit, need not be identical with the corresponding elements of each character transversal character when writing.

如图9A、9B、9C所示,竖向书写时所有种类字符具有的显示单元的尺寸都是一致的,与各种字符的相应字符单元的尺寸无关。 Figure 9A, 9B, 9C shows, when writing the vertical size of the display unit for all kinds of characters have are the same, regardless of the size of the character corresponding units of various characters. 举例来说,在竖向书写时,包括字符之间的间隙,一个英文字母在画面上占据的全部区域,应与一个音节韩国语文字字符占据的全部区域相同。 For example, the entire area at the same vertical writing, including the gap between characters, an entire area occupied by the letters on the screen should be a syllable with Korean text characters occupied. 在横向书写时如果采用字体数据,则由于英文字符单元的宽度为一个音节的韩国语文字字符单元宽度的一半,所以在显示竖向书写的英文时,正如图9C所示,在显示单元中的英文字符单元的位置,应被包含在韩国语文字字符单元的右侧一半中。 If the font data, since the width of the character cell for the English half of a Korean syllable literal character cell width in the transverse writing, so when displaying vertical writing in English, as shown in FIG. 9C, the display unit Location English characters unit should be included in the right-hand half of the Korean text characters unit. 在竖向书写时,由于根据下划线指定的下划线的位置位于字符单元的右侧,所以显示单元的结构与横向书写时的不同,它可根据接收机的视野分别确定。 When vertical writing, due to the right of the character unit according to the specified location underscore underscore, so different structures and horizontal display when writing unit, which can be determined according to the vision of the receiver, respectively. 然而,在竖向书写时,显示单元的大小亦应能够包含各种文字的字符单元。 However, when the vertical writing, should be able to display the size of the unit contains a variety of text characters unit.

在竖向书写时,由于列间隙比行间隙窄的话不易读出,所以最好对字幕区域内的字符行列结构进行重组。 When vertical writing, due to the column gap is narrower than the gap if the row is not easy to read, the characters in the ranks of the structure so it is best to restructure caption area. 也就是说,在竖向书写时,为使列间隙变宽,显示在接收机的列数为16列,每一列可显示的字符个数为10个。 That is, when the vertical writing, in order to widen the column space, the number of columns in the display of the receiver 16, the number of characters that can be displayed for each column 10. 在竖向书写时,由于各种字符具有相同尺寸的字符单元,所以若在整个画面上显示字符,采用10行16列的字符行列结构。 When vertical writing, due to a variety of characters with the same size of character cell, so if the characters on the entire display screen, using the character line structure 10 rows 16 columns. 该字幕区域与横向书写时的字幕区域的横向宽度相同,其高度应略低些或相等。 The caption area and the lateral area of the transverse width of subtitles when writing the same, the height should be slightly lower or equal. 因此,竖向书写时的列间隙,比横向书写时的列间隙更宽些,行间隙可更窄些或相等,因此更容易进行竖向书写。 Thus, when writing the column vertical clearance than lateral clearance when writing the column wider more, narrower line gap may be more or equal to, and therefore easier to vertical writing. 列间隙应为等间隔。 Column clearance should be equally spaced.

竖向书写时,如果没有接收到特别的位置控制码,则接收机的缺省(default)位置定为第16列的第一个字符位置。 When vertical writing, if not received the special position control code, the receiver's default (default) position as the first character position of the first 16.

在竖向书写时,以字符行进方向的竖列作为基准来确定光标移动控制码(APDR、APUR、APF、APB、n-APF)的有效(active)位置方向。 When vertical writing to the direction of travel vertical column character as a benchmark to determine the cursor movement control code (APDR, APUR, APF, APB, n-APF) effective (active) position direction. 即,定义为向下=左侧,向上=右侧,向前=下侧,向后=上侧。 I.e., defined as down = left = right side up, forward = lower side, upper side = back. APDR被定义为用于'移动至正左列最上面的字符位置(第一行位置)′的控制码。 APDR is defined as a 'position of the characters to the positive uppermost left column (the first row position)' control code. APUR被定义为用于'移动至正右列最上面的字符位置(第一行位置)′的控制码。 APUR is defined as a 'moving to the positive column of the right character position, the uppermost (first row position)' control code.

在竖向书写时,2~5行上滚动码是,在包括当前字符显示位置(光标位置)的、由右侧2~5个竖向字符列(column)构成的窗口内部,使窗口内容向画面右侧滚动一列显示的控制码。 When vertical writing, 2-5 on line rolling code is included in the current character display position (cursor position), the inside of the window from the right side of 2 to 5 vertical character columns (column) constituted to make the window contents the right side of the screen to scroll a list of control codes to display. 它使被选定的窗口中的字符列的最右侧列随滚动而消失,同时使最左侧的一列由被最新解码的字符所代替。 It is selected so that the rightmost character in the window with the scroll column column disappear, while the leftmost column of the character to be the latest decoded replaced. 在使用该控制码时,不需要再使用其它的APDR(在竖向书写时,移动至左侧列最上边的字符位置)码,2~5列窗口以外的全部区域由透明颜色所擦除。 When using this control code, do not need to use other APDR (when vertical writing, moved to the left uppermost position of the character columns) code, the entire region of 2 to 5 other than a transparent window to erase colors. 在竖向书写时,2~5行下滚动码是,在包括当前字符显示位置(光标位置)的、由左侧2~5个竖向字符列(column)构成的窗口内部,使窗口内容向画面左侧滚动一列并显示的控制码。 When vertical writing, lines 2 to 5 under rolling code, in including the current character display position (cursor position), the inside of the window from the left side of 2 to 5 vertical character columns (column) constructed so that the window content to the left side of the screen to scroll a list of control code and displayed. 它使被选定的窗口中的字符列的最左侧列随滚动而消失,同时使最右侧列由被最新解码的字符代替。 It makes the selected window to the left-most column of character columns with scrolling disappear, while the right-most column of the character instead of the latest from being decoded. 在使用该控制码时,不需要再使用其它的APDR(在竖向书写时,移动至右侧列最上边的字符位置)码,2~5列窗口以外的全部区域由透明颜色所擦除。 When using this control code, do not need to use other APDR (when vertical writing, to move the right column uppermost position character) code, the entire region of 2 to 5 other than a transparent window to erase colors.

下面说明用于附加信息的控制码。 The following description of the control code for the additional information.

附加信息由于是以页为单位传送字符码,所以需要用于页处理的′页开始′、′页结束′等控制码。 Due to the additional information is transmitted as a unit character code page, so you need to handle the page 'start page', 'end of the page' and other control codes. ′页开始′相当于台词字幕的′两行上滚动′控制码,′页结束′相当于台词字幕的′两行下滚动′控制码。 'Start page' equivalent lines of subtitles 'roll on the two lines' control code 'page end' equivalent lines subtitle 'The next two lines rolling' control codes.

○页开始:表示附加信息的一页开始,接收机在接收到该控制码时开始一页的存储。 ○ Start Page: additional information indicating the start of a page, the receiver upon receipt of the start page of the control code storage. 若在页开始时没接收到该控制码,则放弃该页的全部数据。 If you did not start when the page receives the control code, then give up all the data page.

○页结束:表示附加信息的一页结束,接收机在接收到该控制码时在画面上显示已接收到的该页数据。 ○ Page End: additional information indicating the end of a page, the receiver displays the received data on a screen page when receiving the control code.

在附加信息换行时,必须传送APDR、APUR和列位置指定控制码中的一个。 Additional information exchange in a row, must be transferred APDR, APUR and columns specify the location of a control code.

在画面上显示一页附加信息数据之前,应当由要显示的页的底颜色擦除画面,所以需要一页单位的底颜色。 Additional information page before displaying data on the screen should be displayed by erasing the screen background color pages, so you need a page background color units. 可将紧接在′页开始′码后的下一个底颜色码当做该页底颜色,若紧接在′页开始′码之后未接收到底颜色码,则采用以前的页底颜色作为页底颜色。 You can immediately 'start page' next after the end of the color code as the code page background color, if immediately after the 'start page' is not receiving yards in the end, after the color code, the use of color as the bottom of the page before the page background color .

由于竖向书写本来是用于新闻等具有下部字幕的场合,因此可以忽略。 Because vertical originally written for news and other occasions has a lower subtitles, so you can ignore. 并且,还可以忽略3~5行上滚动和3~5行下滚动。 And can also be ignored and the lower roll 3 to 5 rows on 3-5 line scroll.

下面说明有效码的判别及其处理方式。 The following describes the effective identification and treatment codes.

接收机对字幕信号解码并判别有效码的步骤及处理过程,按下述的顺序进行。 And a receiver for decoding the caption signal discrimination step and processing valid code, according to the following order.

1.只有D7与D16相同,才判定为有效码。 1. Only D7 and D16 the same code was determined to be valid.

2.检查D17和D0D1D2D3D4D5D6D7D8D9D10D11D12D13D14D15D16是否相同,当完全相同时判定为有效码。 2. Check the D17 and D0D1D2D3D4D5D6D7D8D9D10D11D12D13D14D15D16 are the same, determined to be valid when the identical code.

3.若D5、D6分别为(0,0)、D14、D15也分别为(0,0),则判定为控制码。 3. If D5, D6, respectively (0,0), D14, D15, are set to (0,0), it is determined as a control code. 若D5、D6分别为(0,1)或(1,0)或(1,1),而D14、D15分别为(0,1)或(1,0)或(1,1),则判定为字符码。 If D5, D6, respectively (0,1) or (1,0) or (1,1), and D14, D15 respectively (0,1) or (1,0) or (1,1), it is determined character codes. 若D5、D6和D14、D15中的某一个分别为(0,0),而另一个为(0,1)或(1,0)或(1,1),则由于不存在同时接收到控制码和字符码的情况,故该码被判定为误码。 If D5, D6 and D14, D15, respectively in one (0,0), and the other is (0,1) or (1,0) or (1,1), since there is no simultaneous reception of a control case code and character codes, so the code is judged to be errors.

4.如果在上述步骤3中判定为字符码时,则检查D8和D0D1D2D3D4D5D6D7是否相同,当不相同时判定为误码。 4. If it is determined that the character code in step 3 above, it is checked whether the same D0D1D2D3D4D5D6D7 D8 and, when it is determined that errors are not the same.

5.如果在上述的步骤4中判定为不是误码,则确认是否为KSC5601定义的字符码,若是没定义的码则显示为′? 5. If it is determined not error, it is confirmed whether KSC5601 defined character code, if the code is not defined is displayed as' in the above step 4? ′或′■′,若是定义的码则在画面上显示该字符。 'Or' ■ ', if the definition of the character code is displayed on the screen.

6.如果在上述的步骤3中判定为控制码时,则检查低字节中的D0和D1D2D3D9是否相同,及D4和D1D2D11D12是否相同,当上述两个中只要有一个不相同时,判定为误码。 6. If the control code is determined, it is checked in the low byte D0 and D1D2D3D9 are the same, and D4 and D1D2D11D12 are the same, when in the above step 3 above two As long as there is a one in not the same, it is determined that the error.

7.如果在上述步骤6中判定为不是误码,则确认是否由图5所示的控制码表定义,若是没定义的码则判定为误码,若是定义的控制码,则进入等待重复传送同一低位字和高位字的状态。 7. If the error is not determined, it is confirmed whether defined by the control code table shown in Fig. 5, if it is determined that no definition is the error code, if the control code is defined, the process proceeds to wait repeatedly transmitted in the above step 6 the same low word and the high word of the state.

8.若重复传送同一低位字和高位字时,则应用该控制码。 8. If the repeated transfer of the same low word and high word, the application of the control code.

上述的有效码的判定和处理方式表示最佳实施例,也可以应用与此相类似的变形实施例。 Determining said valid code and processing represented preferred embodiment, can be applied to this modified embodiment similar. 举例来说,控制码也可以具有不同的奇偶校验位的组合形式。 For example, the control code may also have different combinations of the parity bit. 尤其是为了防止控制码的误码,可以采用多种不同的方式。 In particular, in order to prevent the error control codes can be used in many different ways.

下面说明如上所述的本发明的作用效果。 The following describes effects of the present invention as described above.

通过采用上述的控制码和字符码的组合,开显示种类可包括台词字幕滚动显示法、台词字幕弹出显示法、附加信息显示法等三种。 By using control codes and character codes combination of the above, the opening lines of display types can include text scrolling display method, lines subtitle pop-up display method, additional information is displayed in three law.

在横向书写和竖向书写中若组合上滚动和下滚动控制码,可以向上、下、左、右四个方向产生滚动。 If the combination of rolling and rolling under control code, you can up, down, left and right direction of writing produced in the lateral and vertical scrolling in writing.

首先对横向书写时的上滚动进行说明,而省略了对向下移动的说明。 First, when writing to the transverse rolling is described, and a description thereof will move downward. 传送码串由<黑底-黑底-白字-白字-横向书写-横向书写-第十行-第十行-第二列-第二列-开显示-开显示-(表示韩国语发音)“da”-“um”-“un”-空格(space)-R-OL-L-“pyo”-“shi”-“hup”-“eui”-“de”-“ei”-“ta”-空格-“jun”-“song”- “ae”>构成。 Transfer code string by & lt; black - black - white - white - Landscape Writing - Writing Lateral - line 10 - the tenth row - second row - second row - open display - open display - (expressed pronounce Korean) "da" - "um" - "un" - a space (space) -R-OL-L- "pyo" - "shi" - "hup" - "eui" - "de" - "ei" - "ta" - Space - "jun" - "song" - "ae" & gt; composition. 因此,如图10所示,在画面的黑底上显示出了白字。 Thus, as shown in FIG. 10, the screen shows black and white. 接着,传送的码串若为<两行上滚动-两行上滚动-“dae”-“han”-“ye”-“rul”-空格-“bo”-“in”-gut-“ei”-“da”-.>,则如图11所示,在画面上滚动一行。 Next, if the code string is transmitted & lt; roll on two lines - roll on two lines - "dae" - "han" - "ye" - "rul" - space - "bo" - "in" -gut- "ei "-" da "-. & gt ;, as shown in Fig 11, scroll one line on the screen. 同样地,若接着传送的码串为<两行上滚动-两行上滚动-“to”-“han”-空格-“iul”-“eul”-R-OL-L--UP-“shi”-“kin”-“da”-.>,则如图12所示,擦除第9行的字符列并向上移动一行。 Similarly, if a code string is then passed to & lt; roll on the two lines - roll on the two lines - "to" - "han" - space - "iul" - "eul" -R-OL-L - UP- " shi "-" kin "-" da "-. & gt ;, is shown in Figure 12, the erase character column 9th row and move one line.

下面对竖向书写时向左侧的滚动进行说明,而省略了向右侧移动的说明。 Next, the writing will be described when the vertical scroll on the left side, and move to the right side is omitted the description. 传送码串为<关显示-关显示-黑底-黑底-白字-白字-竖向书写-竖向书写-第二行-第二行-第十五列-第十五列-开显示-开显示-“ei”-“bun”-“ae”-“nun”-空格-“se”-“ro”-“seu”-“gi”-APDR-APDR-ROLL-空格-“pyo”-“gi”-“eui”-空格-“ye”>。 Transfer code string for & lt; Off Display - Off Display - black - black - white - white - Vertical Writing - Vertical Writing - second row - second row - the fifteenth column - fifteenth column - On Display - On Display - "ei" - "bun" - "ae" - "nun" - space - "se" - "ro" - "seu" - "gi" -APDR-APDR-ROLL- space - "pyo" - "gi" - "eui" - space - "ye" & gt ;. 因此如图13所示,在画面的黑底上以竖向书写方式显示白字。 Thus as shown in Figure 13, the black screen display in vertical writing white. 接着,如果传送的码串为<两行上滚动-两行上滚动-APDR-APDR-“rul”-空格-“bo”-“in”-空格-“gut”-“ei”-“da”-。 Then, if the transmission code string for & lt; rolling on two lines - Scroll -APDR-APDR- "rul" on two lines - space - "bo" - "in" - space - "gut" - "ei" - "da "-. >,则如图14所示,在画面上向左侧滚动一行。 & Gt ;, as shown in Fig 14, scrolled one to the left on the screen.

如图15至17所示,根据本发明的软滚动,也可叫做一扫描线上滚动。 As shown in Figure 15 to 17, based on the soft roll of the present invention can also be called a scan line scroll.

即,如图15所示,在进行2行上滚动的状态下,观众若用遥控器选择软滚动,用字幕处理器从显示存储器中读出字符数据时,不是以每一行读出,而是一边使扫描线一条一条地变化一边读出。 That is, as shown in Figure 15, during the two-line scroll state, when the audience if you choose a soft roll with a remote control, with the subtitle processor reads the character data from the display memory is not read out each line, but while the scan line changes while a read-out. 也就是说,把每一行上滚动的时间进行20等分后,按每条扫描线上滚动,以使显示的字幕按图15、16、17的顺序柔和地滚动。 That is, the rolling time on each line is divided by 20, according to each scan line rolling, so that the caption display sequentially FIG 15,16,17 gently rolling.

由于不知道接收机何时工作,所以播放经营者应制造每四秒左右播放一次对应显示位置的控制码的、适当地配置发射机的符号串的播放系统。 Since the receiver does not know when the work, the operator should therefore play manufacturing about once every four seconds playback position corresponding to the display control code, suitably configured transmitter symbol string playback system. 在接收机工作后,不知道正确的位置和工作模式时,基本服务规定的接收机在缺省位置显示接收到的字符码,若接收到每四秒钟一次的控制码,则擦除现有显示画面,按新的控制码进行工作。 After the receiver is working, do not know the correct position and operating mode, the receiver receives the basic services provided to show the character code in the default location, if received once every four seconds, the control code, then erase the existing display, according to the new control codes to work.
