The display device according to the related art includes a tuner and a demodulator 100, a codec 110, a storage unit 120, a playback unit 130, a display unit 140, a controller 150, and a remote controller 160. It's about DTV.

The tuner and demodulator 100 receives an arbitrary TV broadcast signal transmitted from the relay station and performs demodulation processing.

The tuner and demodulator 100 tunes a broadcast signal of a predetermined channel under the control of the controller 150, and demodulates and outputs the broadcast signal of the tuned channel and all program related information included in the broadcast signal. The program related information includes information indicating what genre of broadcast program the current channel is.

For example, it includes program information such as whether the current program is a drama, a movie, a sports, or a documentary. If the channel itself is specialized, it is a drama channel, a movie channel, a sports channel, or a documentary channel. Information may be included and information indicating whether or not the channel is a minor channel.

Video and audio signals and program related information output from the tuner and demodulator 100 are input to the codec 110.

The codec 110 performs decoding and encoding of video and audio signals, channel or program information under the control of the controller 150, and stores necessary information using the storage 120.

The playback unit 130 reproduces an image signal output from the codec 110 under the control of the controller 150 and transmits the image signal to the display unit 140. The display unit 140 displays the input image signal. Here, the display unit 140 may use various display devices such as a CRT, a PDP, an LCD, and the like, and basically supports the multi picture by the playback unit 130.

The controller 150 displays a program of a corresponding channel or genre among a broadcast channel or a program decoded by the codec 110 based on the program-specific setting information stored in the storage 120 through the display unit 140. ).

2 is a flowchart of content display according to the prior art.

The content display according to the prior art is displayed based on the setting information for each program.

First, a multi picture selection channel menu is displayed as a user's control command through the remote controller 160 and input of display setting information for the multi channel (S200).

When the display of the user's multi-picture selection channel menu is requested through the remote controller, the controller 150 controls the display unit 140 to display a corresponding menu screen.

The user selects a preferred multi-picture item using a direction key of the remote controller 160 through the menu screen, and the controller 150 displays the item selection screen (S210). The item selection screen is the same as the main screen for displaying the minor channel of the main screen on the multi-picture sub screen, and the same genre and main screen for displaying the same genre or program as the main screen on the multi-picture sub screen. Each genre for displaying a specific genre channel or program is displayed on the multi-picture sub-screen.

In particular, when each genre item is selected, a reserved channel screen for matching a channel or program of a specific genre is further displayed for each screen of the multi-picture. If there are three sub-screens, the reserved channel screen designates a channel or program of a genre to be matched to each sub-screen. In order to designate, for each sub-screen, selectable items, for example, selection items such as movies, dramas, sports, and news are prepared in advance, and when the information is selected by using the remote controller 160, the corresponding information is selected. This is achieved by matching each sub-screen to store in the storage 120.

In the selection item determination step S220, the control unit 150 determines the selection item information stored in the storage unit 120 and displays the corresponding channel or program on each screen of the multi picture according to the determination result. That is, the controller 150 reads setting information (screen: matching information of channels and genres) stored in the storage 120 according to the display of the multi-picture selection channel menu step S200 and the item selection step S210. Recognizing this, the corresponding channel or program of the appropriate genre is displayed on the multi-picture screen according to the channel and program genre decoded by the codec 110 and displayed (S230, S240, S250).

For example, if the result of the selection of the selected item is a minor channel, when the major channel is displayed on the main screen 300, the minor channels of the main screen are sequentially displayed on each subscreen. The implementation of this function is achieved by sequentially displaying the minor channels of the physical band of the digital channel selected by the user in the multi-picture.

As another example, if the content set by the user is the same genre as the main screen, the channels or programs having the same genre as the main screen are sequentially displayed on the sub screen. Here, when the sports channel is displayed on the main screen, the sports channel is displayed on the sub screen, the sports channel is displayed on the sub screen, and the sports channel is displayed on the sub screen.

The implementation of this function is to pre-set the desired channels for each genre, and then display the channels of the same genre as the main screen as a multi-picture by the user's selection, or the program loaded on the transmitted TV broadcast signal as described above. The channel related information may be used to display channels of the same genre as the main screen as a multi picture.

3 is a diagram illustrating a screen for displaying a content according to the prior art.

The display unit 140 for displaying content according to the related art has a multi-picture display form based on a main screen 300 displaying a major channel and three sub-screens 310, 320, and 330 displayed in a mulberry picture form. It is composed.

According to the related art, a multi-picture display is controlled by selecting and displaying a channel or program of a specific genre on each screen of a multi-picture based on grouping of channels or programs by genre. To this end, the user sets in advance which genre of channels or programs of a genre to be displayed on the sub-screens 310, 320, 330 of each of the multi-pictures by using the remote controller 160. The matching information between the set channel, the program, and the screen is stored in the storage unit 120.

For example, setting information about a specific channel or a specific genre of a program to be matched with each screen of the multi picture may be set to any one of three types illustrated as follows.

The first is a type of sequentially displaying the minor channels of the main screen 300 in the three sub-screens (310, 320, 330) of the multi-picture when watching the broadcast channel on the main screen 300, the second is the main screen ( When selecting and watching a channel of a specific genre such as a movie or a drama, the multi-picture three sub-screens 310, 320, and 330 sequentially display channels or programs of the same genre as the main screen. Irrespective of the main screen 300, channels of different genres and programs are matched and displayed on each of the three sub-screens 310, 320, and 330 of the multi picture.

For example of the third type, even though a movie channel or a movie program is displayed on the main screen 300, the first sub screen 310 matches only the drama channel or the drama program and displays the second sub screen 320. There is a type to display only match the news channel or news program, and the last sub-screen 330 to match and display only the sports channel or sports program.
