Description
Background of invention
Technical field
The field of the present invention relates to is coding and the compression method that is used for the electronic signal of signal record, regeneration, transmission, particularly is used to encode, decodes, the method and apparatus of compression, decompress(ion), record and transmission electronic signal, audio signal, computer data signal and HTML(Hypertext Markup Language) static state and living document.
Prior art
In the U.S. and Japan, provide the TV signal that comprises video and audio-frequency information according to national television systems committee (NTSC) signaling mode standard, in Europe, institute's accepted standard is line-by-line inversion (PAL) standard and SECAM ("systeme electronique couleur avec memoire") standard.HDTV (high definition TV) and other standards also are possible, from now on, though other standards should be considered, only use Unite States Standard under discussion.It is analog AM (AM) the vision signal carrier wave at center that the NTSC signal comprises with 1.25MHz, be the colour signal subcarrier at center with 3.58MHz and be frequency modulation (FM) voice carrier at center with 4.5MHz on the vision signal carrier wave.(AM) vision signal is very easily affected by noise, the NTSC quality of signals that is sent that noise can destroy and demote and be received and shown by television receiver.
In the U.S., broadcast standard is safeguarded by collaborative International Telecommunication Union of Federal Communications Committee (FCC), from now on, though other standards should be considered, is only used Unite States Standard under discussion.In the U.S., the commonsense method of broadcast wireless signal is to use carrier signal frequency modulation (FM).(FM) radio broadcasting signal does not have to destroy when sending and the noise of degraded signal quality inherently.
Standard once (FM) radio broadcasting signal carrier wave is that 150KHz and total bandwidth are that 200KHz carries out frequency modulation with the maximum frequency deviation.Standard (FM) radio broadcasting stereophonic signal comprises frequency displacement, and signal and frequency are the pilot subcarrier signal of (19KHz) frequently for the left side of (23 to 53KHz) subtracts the right side (L-R) difference tone for the left side of (0 to 15KHz) adds the right side (L+R) audio signal, frequency displacement.(FM) but wireless system mainly sends music and audio-frequency information can not send the NTSC signal at present or be higher than the high-speed computer data-signal of per second 20,000 bits.Wireless system can only once send audio signal on (FM) signal at present.The another kind of method of broadcast wireless signal is to use carrier signal amplitude modulation (AM).(AM) wireless signal is very easily affected by noise, the quality of signals that noise jamming, destruction and degradation are sent.(AM) wireless system mainly sends music and audio-frequency information, but can not send the NTSC signal at present.
The secondary singal of a signal " back of the body carries (piggyback) " also can be broadcasted in the broadcasting station that utilizes (FM) to broadcast their signal.This " back of the body carry " signal (piggyback signal) is the assistant service that is called subsidiary communications mandate (SCA, Subsidiary Communications Authorization), is used for receiving to selected reservation the reception unit broadcasting of this special broadcasting.(FM) broadcasting station of the stereophonic broadcasting of a signal of use also can be broadcasted and be comprised the SCA signal of Audio-Frequency Frequency Shift for (59.5 to 74.5KHz).If the stereophonic broadcasting (monaural) of a signal is not used in the broadcasting station, it also can be broadcasted simultaneously and comprise the two SCA signal of Audio-Frequency Frequency Shift for (20 to 53KHz) so.The applicant believes that wireless system can only send a kind of signal type at present at every turn on the SCA signal.
Network technology has developed the interference networks of a computer system, is commonly referred to as internet and world wide web (www).The internet uses the conduct of transmission control protocol/Internet Protocol (TCP/IP) standard in the means that are connected to the transmission data between the computer of internet.Other standards also are possible, from now on, though should consider other standards, but only use the TCP/IP standard under discussion.It is believed that the internet does not have ability to send can be on any display monitor viewed NTSC signal with the full speed movement display rate stipulated in the NTSC standard at present, this causes comparing ropy visual display effect with the NTSC display monitor that moves at full speed.The applicant believes that the NTSC signal that present internet sends is used for showing on the non-computer display that interweaves, and can not show on the televimonitor that NTSC interweaves.
Be used for to video, audio frequency and data-signal Code And Decode be to use computerized algorithm to compress with the common format that is used to send, write down and receive and decompress(ion) to reduce expression desired data volume of signal and bandwidth.These algorithms are often used in by the internet and come transmission of video, audio frequency and data.Some prevailing algorithms that use are associating picture experts group (JPEG), motion picture expert group (MPEG), MP3, MNP, international Telephone and Telegraph Consultative Committee (CCITT), LZW (V.42 second edition) and Microsoft (MS-Audio).Extended formatting also is possible, from now on, though should consider extended formatting, but only use jpeg format under discussion.At present, the use that is applied to the compression algorithm technology of vision signal and audio signal has caused stopping of visual display and audio signal and beginning, discontinuous fluid (jerking movement) type.What believe this result is because signal is sent out and the characteristic issues of the hardware of the primary signal that is used for receiving, shows and regenerates.Utilize compression algorithm at present, the data that sent flow to the receiving equipment memory that is used to cushion continuously, but because the information of stream can be interrupted, therefore can cause discontinuous stream.
Html file is also referred to as network file, is one of computer data signal of the most normal transmission on the internet.These network files can be static, and wherein graph text information does not change when showing.Network file also can be dynamic, and the image that wherein is shown, text and computer operation can change, because small computer program (as Java Applet and Active-X applet) is attached on one of file, data or both.Extended formatting as XTML and SGML, also is possible, from now on, though should consider extended formatting, only uses html format under discussion.Html file more is everlasting and is shown that they also can be displayed on the scanning computer monitor that interweaves that has used special (WEB-TV (Web TV)) receiver on the non-scanning computer monitor that interweaves.
Summary of the invention
The applicant believes the present invention's provide coding, decode, send, receive, write down and regenerate a kind of method and apparatus of means of multiple signal of above-mentioned signal standards and form.In a kind of sending method, FM is wireless, and SCA broadcasting is used to send code signal to the SCA receiving system.This receiving system uses FM radio-circuit, computer and comprises the signal decompress(ion) modulator of the phase-locked loop circuit of coupling, is used for the code signal of decoding and being sent.
