Receives digital broadcasting data compressed by a moving picture experts group (MPEG) -2 method, and transmits the compressed data, decodes the encoded data, and converts the encoded data into a standard NTSC signal to be displayed on a TV receiver.

That is, the digital broadcast receiver receives a bit-stream type digital broadcast signal transmitted by a broadcasting station and broadcasts a channel selected from the broadcast signals received by transport demux. It is configured to extract the signal, and to display the extracted broadcast signal after decoding the MPEG-2 scheme.

Meanwhile, in the digital broadcast receiver, the user may check broadcast program information of all channels using EPG (Electronic Program Guide) information.

However, in confirming channel information in a conventional digital broadcasting receiver, a channel information menu key is input, and a channel desired for channel information is searched in and checked on a menu screen divided by genre, so that broadcast program information for each channel can be checked. There was a problem that was very cumbersome to confirm.

Therefore, the present invention implements a menu screen for searching channel information in the lower part of the broadcast program screen when the channel information guide request is made while the digital broadcast receiver displays the broadcast program of the currently tuned channel. The present invention seeks to provide a channel information retrieval method in a digital broadcasting receiver capable of checking time-based broadcast program information of each channel.

As described above, the present invention provides a method for retrieving channel information in a digital broadcast receiver, the method including receiving a channel information guide request while playing a broadcast program of a specific channel in a digital broadcast receiver, and receiving channel information at the bottom of the broadcast program when the channel information guide request is received. Displaying a search menu; and displaying time-based broadcast program information of a corresponding channel when selecting a specific channel from the channel information search menu.

In the present invention, in the method for retrieving channel information in a digital broadcasting receiver, when a channel information guide request is performed while displaying a broadcast program of a currently tuned channel, a menu screen capable of retrieving channel information in a lower portion of the broadcast program screen is implemented. When the specific channel is selected, the broadcast program information for each channel of the selected channel is displayed in detail, so that the broadcast program information for each channel received from the digital broadcast receiver can be easily checked.

Hereinafter, with reference to the accompanying drawings will be described in detail the operating principle of the present invention. In the following description of the present invention, when it is determined that a detailed description of a known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

Referring to FIG. 1, first, the key input unit 118 and the remote controller 126 generate a key data signal according to a user's key operation and apply the generated key data signal to the controller 116. The memory unit 120 stores an operation program for the operation of the digital broadcast receiver, and stores and outputs various program information output from the tuner unit 100 under the control of the controller 116.

The tuner 100 tunes and receives a bit stream of a channel corresponding to the tuning control signal of the controller 116 among bit streams received from the terrestrial wave or satellite. The channel decoder 102 decodes the signal tuned from the tuner 100 in a manner such as VSB, QPSK, QAM, etc. according to a transmission method, and applies the demultiplexer 104 to the demultiplexer 104.

The demultiplexer 104 receives the digital stream decoded by the channel decoder 102 and divides the digital stream into a video, audio, and additional information stream and applies the decoded stream to the A / V decoder 106. In this case, the A / V decoder 106 may be, for example, an MPEG-2 decoder. Then, the A / V decoder 106 separates and decodes the broadcast signal provided from the demultiplexer 104 into an audio signal and a video signal, and then performs a predetermined signal processing process through the video / audio processing units 108 and 110 to receive a TV receiver. The display unit 112 is displayed on the screen.

The video processor 108 receives a video signal decoded and output from the A / V decoder 106 and converts the video signal into a displayable image signal on a screen of the display 112 of a TV receiver such as a CRT, a PDP, an LCD, or the like. The audio processor 110 receives the audio signal decoded and output from the A / V decoder 106 and reproduces the audio signal through the audio output unit such as the speaker 114. The IR receiver 124 receives an operation command of a remote controller operated by a user and applies it to the controller 116.

The controller 116 controls the overall operation of each part of the digital broadcast receiver according to the operation program stored in the memory unit 120, and the remote controller 126 input from the key data signal from the key input unit 118 and the IR receiver 124. According to the key data from the control signal for generating a corresponding function is generated and applied to the corresponding function. For example, the tuner 100 provides a tuning control signal for tuning a broadcast channel selected by a user, and generates a decoding control signal for decoding the tuned broadcast signal.

In addition, the controller 116 implements a menu screen capable of retrieving channel information in a partial region of a broadcast program screen when a channel information guide request is made while displaying a broadcast program of a currently tuned channel according to an embodiment of the present invention. When selecting a specific channel for which a search from the user is requested, the broadcast program information according to the selected channel is displayed in detail on an OSD screen. Accordingly, the user can more easily check the broadcasting program information for each channel received by the digital broadcasting receiver.

2 illustrates an operation control flow for simply searching for channel information during viewing of a channel broadcast program in a digital broadcast receiver according to an exemplary embodiment of the present invention. Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

First, when there is a power-on key input through the key input unit 118 or the remote controller 126, the controller 116 of the digital broadcast receiver turns on the power of the digital broadcast receiver at step S200, and at step S202. In step, the broadcast of the channel previously watched is displayed.

Accordingly, a user may watch a broadcast program of a channel previously watched, or use a key input unit 118 or a remote controller 126 implemented on the front panel of a digital broadcast receiver to watch a channel for broadcasting another desired channel. You can also switch.

In this case, when there is a channel switch request key input from the user, the controller 116 recognizes the channel switch request in step S204, and proceeds to step S206 to tune to a channel keyed by the user to broadcast the corresponding channel. Is displayed.

On the other hand, the user watching the broadcast of the other channel while switching the channel as described above, if you want to easily check the broadcast program information for each time zone of the other channel while watching the broadcast of the current channel according to the present invention, the key input unit 118 or the remote control ( The channel information search menu key implemented in 126 is entered to request channel information search.

 Then, the controller 116 recognizes the channel information search request in step S208, and in step S210, a digital screen is displayed in a part of the broadcast screen of the channel being watched by the user, for example, in a lower part of the screen, as shown in FIG. The OSD displays a channel information search menu screen 300 implemented to select all channel numbers received by the broadcast receiver. In this case, the entire channel number displayed by the OSD in the channel information search menu is implemented at the bottom of the broadcast screen, for example, by scrolling, so that the user can scroll the entire channel number by scrolling.

Accordingly, the user selects the corresponding channel when he / she wants to view time-based broadcast program information of the desired channel number while moving the channel number displayed by the OSD using the direction key implemented in the remote controller 126.

Then, the controller 116 recognizes the channel number selected on the channel information search menu screen 300 in step S212, and the broadcast program information 302 for each time of the channel selected by the user in step S214. As shown in, the OSD is displayed on the upper part of the channel number smaller than the full screen of the broadcasting program currently being viewed.

Accordingly, the user can easily check the broadcast program information of the desired channel by time through the broadcast program information 302 displayed in the OSD as shown in FIG. 3.

In this way, the user who simply checks the broadcast program information by time for the channel if the channel no longer wants to check the broadcast program information is inputted to the channel information search menu screen end key.

Then, the control unit 116 checks whether the end key is input through the key input unit 118 or the remote controller 126 in step S216 and checks that the channel information search menu end key is input in step S218. In FIG. 3, the channel information search menu screen 300 displayed in the OSD disappears from the lower part of the broadcast screen of the channel that the user is currently watching.

Meanwhile, in controlling the channel information search menu screen to disappear, the controller 116 does not select any channel for a predetermined time after the initial display of the channel information search menu screen in step S220, or selects in step S216. If there is no key input for a predetermined time after displaying the program information of the channel by time, the process proceeds to step S218 and the channel information displayed in the OSD as shown in FIG. 3 on the lower part of the broadcast screen of the channel the user is currently watching. The search menu screen 300 is made to disappear.

As described above, in the present invention, in the method of retrieving channel information in a digital broadcasting receiver, a menu screen capable of retrieving channel information is displayed in a lower portion of the broadcast program screen when a channel information guide request is made while displaying a broadcast program of a currently tuned channel. After the implementation, when the specific channel is selected, the broadcast program information of the selected channel is displayed in detail so that the broadcast program information of each channel received by the digital broadcast receiver can be checked more easily.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
