Description

    CROSS-REFERENCE TO RELATED APPLICATIONS
  • This application claims priority from Korean Patent Application No. 10-2007-0109807, filed on Oct. 30, 2007 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety.
    • BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • Apparatuses and methods consistent with the present invention relate to a broadcast receiving apparatus and a control method thereof, and more particularly, to a broadcast receiving apparatus which provides a graphical user interface (GUI) which a user is able to control using a pointing device, and a control method thereof
  • 2. Description of the Related Art
  • With the use of a computer mouse as an input device for a personal computer (PC), pointing devices have become increasingly used to control graphical user interfaces (GUIs) of broadcast receiving apparatuses. Pointing devices may also be used to control televisions (TVs), and recently, remote controllers additionally employing functions of a pointing device, and methods for controlling a GUI of TV using the remote controller have been developed.
  • Methods for moving a pointer include a position method and a step method. In the position method, the pointer continuously moves as the pointing device is moved, and in the step method, the pointer moves in a specified direction according to the manipulation of up, down, right, and left direction keys. A mode in which the pointer operates in the position method is referred to as a position mode, and a mode in which the pointer operates in the step method is referred to as a step mode.
  • When a GUI of a TV is displayed using icons, a remote controller used as a pointing device may operate in a position method so that a user may conveniently manipulate the remote controller. However, when a related art GUI requiring manipulation by direction keys is displayed, the pointer does not move in a step method, and may, therefore, be less convenient for a user than a remote controller having direction keys. If a remote controller has functions of a pointing device and direction keys, manufacturing costs increase, and a greater number of keys are required. Accordingly, user convenience is diminished.

Also, well-known functions or constructions are not described in detail since they would obscure the invention with unnecessary detail.
  • FIG. 1 is a block diagram illustrating a broadcast receiving apparatus applicable to an exemplary embodiment of the present invention. Referring to FIG. 1, a broadcast receiving apparatus 100 according to an exemplary embodiment of the present invention may comprise a broadcast signal receiving unit 110, a signal processing unit 120, a speaker 130, a display 140, a memory 150, a command receiving unit 160, a graphical user interface (GUI) generating unit 170, and a control unit 180.
  • The broadcast signal receiving unit 110 may include a tuner (not shown) which tunes to a broadcast signal transmitted from a broadcasting station, and a demodulator (not shown) which demodulates the tuned broadcast signal and corrects errors of the demodulated broadcast signal.
  • The signal processing unit 120 may comprise a demultiplexing unit 121, an audio decoding unit 122, an audio processing unit 123, a video decoding unit 124, and a video processing unit 125.
  • The demultiplexing unit 121 separates a broadcast signal demodulated by the broadcast signal receiving unit 110 into additional data such as video data, audio data, and Program and System Information Protocol (PSIP) data, and outputs the separated data as bit streams.
  • The audio decoding unit 122 decodes audio data separated by the demultiplexing unit 121, and outputs the decoded audio data. The audio processing unit 123 signal-processes audio data output from the audio decoding unit 122 to meet the requirements of the speaker 130, and outputs the signal-processed audio data to the speaker 130.
  • The video decoding unit 124 decodes video data separated by the demultiplexing unit 121, and outputs the decoded video data. The video processing unit 125 signal-processes the decoded video data to meet the requirements of the display 140, including the vertical frequency, resolution, and aspect ratio, and outputs the signal-processed video data to the display 140.
  • The speaker 130 and display 140 output audio and video data received from the signal processing unit 120 as sound and video, respectively.
  • The command receiving unit 160 includes various keys for receiving user commands input by a user, and a remote control receiving unit for receiving user commands transmitted from a pointing device 190. The command receiving unit 160 transmits a key signal corresponding to user commands received through the keys or remote control receiving unit to the control unit 180.
  • A user holds and moves a pointing device 200 to transmit movement information to the broadcast receiving apparatus 100.
  • The GUI generating unit 170 generates a pointer showing the movement of the pointing device 200 under the control of the control unit 180, and a menu or icon indicating the state of the broadcast receiving apparatus 100. That is, the GUI generating unit 170 generates a GUI which receives a user input, and a pointer which operates according to input from the pointing device 200.
  • The control unit 180 controls components of the broadcast receiving apparatus 100 to conduct functions according to a user command received through the command receiving unit 160, and may be embodied as a micro controller, a microprocessor, or a central processing unit (CPU).
  • More specifically, if the pointing device 200 moves according to a predetermined pattern, the control unit 180 reads a function corresponding to the pattern from the memory 150, and performs the corresponding function. For example, if the pointing device moves in a pattern forming the shape of the number ‘8’, the control unit 180 detects the movement corresponding to the pattern.
  • The corresponding function may switch the pointing device 200 between a position mode and a step mode. The control unit 180 stores a pattern function according to a user command in the memory 150. A position method represents a method in which the pointer continuously moves when the pointing device 200 moves, and a step method represents a method in which the pointer moves in a specified direction when up, down, right, and left direction keys are manipulated, as explained above.
  • FIG. 2 is a diagram illustrating a method for controlling a GUI of a broadcast receiving apparatus using a pointing device applicable to an exemplary embodiment of the present invention. In FIG. 2, a menu 102 is provided as a GUI which is operated in a step method, and icons 104 are provided as a GUI which is operated in a position method.
  • A pointer 300 receives a movement signal from the pointing device 200, and moves over the display 140 to select the menu 102 or icons 104. If a user selects a graphic object 106 within a GUI by placing the pointer 300 on the graphic object 106, a GUI control mode is switched between a position mode and a step mode. For example, when the broadcast receiving apparatus 100 is in a position mode, a GUI control mode is converted into a step mode according to the selection of the graphic object 106.
  • FIG. 3 is a block diagram illustrating the pointing device of FIG. 2.
  • A motion sensor 202 senses movement of the pointing device 200 when a user holds and moves the pointing device 200.
  • A memory 208 stores information about pattern functions so that the pointing device 200 transmits the pattern functions corresponding to the movement of the pointing device 200 by the user.
  • A control signal transmission unit 206 transmits to the broadcast receiving apparatus 100 a control signal transmitted from a control unit 204, which will be explained below. The control unit 204 determines whether movement information received from the motion sensor 202 corresponds to a predetermined pattern. If it is determined that the movement information corresponds to a predetermined pattern, the control unit 204 reads a function corresponding to the predetermined pattern from the memory 208, and transmits the function to the broadcast receiving apparatus 100 through the control signal transmission unit 206. On the other hand, if it is determined that the movement information does not correspond to a predetermined pattern, the control unit 204 transmits the movement information to the broadcast receiving apparatus 100.
  • The pattern may be a circle drawn by the pointing device 200, and the function corresponding to the pattern may be that the pointer moves one step.
  • FIG. 4 is a flowchart illustrating a method of controlling a pointing device according to an exemplary embodiment of the present invention. The control unit 204 senses movement of the pointing device 200 (S402), and determines whether the sensed movement corresponds to a predetermined pattern (S404). If it is determined that the sensed movement corresponds to a predetermined pattern, the control unit 204 reads a function corresponding to the pattern from the memory 208 (S406), and performs the read function (S410).
  • If it is determined that the sensed movement does not correspond to a predetermined pattern, the control unit 204 transmits information regarding the movement to a receiving unit (S412). For example, the pattern may be that the pointing device 200 draws the shape of the number ‘8’ in a space, and the function corresponding to the pattern may be that the pointing device 200 transmits a signal corresponding to the direction keys to the receiving unit. Alternatively, the function corresponding to the pattern may be switching between a position mode and a step mode, in which the pointing device 200 may be converted from the position mode to the step mode.
  • FIG. 5 is flowchart illustrating a method of controlling a GUI of a display device according to an exemplary embodiment of the present invention. The control unit 180 receives movement information from the pointing device 200 through the command receiving unit 160 (S502), and determines whether the received movement information corresponds to a predetermined pattern (S504).
  • If it is determined that the movement information corresponds to a predetermined pattern, the control unit 180 reads a function corresponding to the pattern (S506), and performs the function (S510). If it is determined that the movement information does not correspond to a predetermined pattern, the control unit 180 controls the GUI generating unit 170 so that a pointer moves over the display 140 according to the movement of the pointing device 200 (S512).
  • For example, a pattern may be that the pointing device 200 draws the shape of the number ‘8’ in a space, and the function corresponding to the pattern may be switching between a position mode and a step mode.
  • FIG. 6 is a flowchart illustrating a method of controlling a GUI of a display device according to another exemplary embodiment of the present invention.
  • If a selection command is received from the pointing device 200 (S602), the control unit 180 determines whether the selection command selects the graphic object 106 within the GUI (S604).
  • If it is determined that the graphic object 106 is selected by the selection command, the control unit 180 of the broadcast receiving apparatus switches a GUI between a position mode and a step mode (S606). For example, if the control device 180 receives a selection command from the pointing device 200 while a pointer is positioned on an icon (icon 106 of FIG. 2) for switching between a position mode and a step mode, the icon is selected. If the icon is selected, a GUI mode of the broadcast receiving apparatus 100 is switched between a position mode and a step mode.
  • While a position mode and a step mode are described as the GUI modes in the exemplary embodiments of the present invention described above, this should not be considered limiting. The present invention may alternatively be applied to available mode switching. A function corresponding to the pattern may be various functions of the broadcast receiving apparatus 100.
  • When a broadcast receiving apparatus receives functions corresponding to a pattern from a pointing device to control a GUI, mode switching is efficiently performed using the pointing device instead of direction keys.
  • The foregoing exemplary embodiments and advantages are merely exemplary and are not to be construed as limiting the present invention. The present teaching can be readily applied to other types of apparatuses. Also, the description of the exemplary embodiments of the present invention is intended to be illustrative, and not to limit the scope of the claims, and many alternatives, modifications, and variations will be apparent to those skilled in the art.
