4 is a flowchart of the operation of the broadcast operating device. Referring to FIG. 4, the controller 160 of the broadcasting apparatus may control to display a moving image for a channel corresponding to a broadcasting channel selected through the screen output unit 140 (S401). When the user input for dividing the output screen into a plurality of areas is received while the moving image for the channel is output through the screen output unit 140 in operation S402, the control unit 160 displays the output through the screen output unit 140 (Step S403). After stopping the output of the moving image for the channel, the moving image for the mosaic having the same broadcast channel as the moving image for the stopped channel is displayed on any one of the divided areas (S404). In addition, the control unit 160 controls the display unit 160 to display the mosaic video corresponding to the selected broadcast channel and the at least one mosaic video corresponding to the other broadcast channel, (S404). A detailed description thereof will be made with reference to FIG. In Fig. 5, it is assumed that the output screen is divided into four areas that do not overlap with each other, corresponding to the output screen division command of the user. However, the present invention is not limited thereto, and the output screen may be divided into a larger number or a smaller number.

5 is an exemplary diagram for explaining an operation of dividing an output screen into a plurality of areas. The output screen output through the screen output unit 140 before receiving the split screen of the output screen is a screen in which the video for the channel corresponding to the selected broadcast channel is displayed on the full screen . ≪ / RTI > When a user input for dividing an output screen into a plurality of areas is received from a user while a moving image for a channel corresponding to the selected broadcasting channel is outputted on the full screen, the controller 160 stops outputting the moving image for the channel, The output screen to be outputted through the screen output unit 140 is divided into a plurality of areas and then output is stopped through any one of the divided areas as in the example shown in FIG. 5 (b) It is possible to control the mosaic video of the same broadcast channel as that for the moving picture to be displayed and to display the mosaic video of another broadcast channel in the other area.

For example, when the divided regions of FIG. 5 (b) are assumed to be the first to fourth regions from the upper left corner to the upper left corner, respectively, 5 ('II' region, 12 ('III' region) and 4 (second region) are displayed in the second through fourth regions Quot; IV " region), a mosaic movie corresponding to another broadcast channel can be displayed. Thus, the user is able to check the contents currently being broadcasted on other broadcast channels while viewing the mosaic video corresponding to the same broadcast channel as the video for the channel which was output to the full screen before the output screen is divided into four regions There is an advantage.

The other broadcast channels allocated to the second to fourth regions II to IV may be broadcast channels that are not selected, broadcast channels recommended by the broadcast providing server 100, broadcast channels having a high audience rating, A channel, and a usage pattern of a user, and can be determined by various methods such as a viewing frequency, a viewing frequency or a viewing time, a broadcasting channel adjacent to the selected broadcasting channel, and the like.

When the output screen to be output through the screen output unit 140 is divided into a plurality of areas, the controller 160 focuses any one of the divided areas and outputs audio corresponding to the mosaic image output through the focused area, So that a signal can be output. Further, the control unit 160 may separate the focused area from the unfocused area, and control the focused area to respond to user input. A detailed description thereof will be made with reference to FIG.

Fig. 6 is a diagram illustrating one of a plurality of areas to be focused. When the output screen is divided into a plurality of areas by the user, the controller 160 may control the area where the mosaic motion picture of the same broadcast channel as the motion picture for the channel whose output is first stopped to be focused. This is to help the user to watch the broadcast program of the same broadcast channel with continuity even after the output screen is divided into a plurality of areas. 5B, the first area I for outputting the Mosaic video of the same broadcast channel as the moving image for the channel is focused, and the mosaic output from the first area I The audio signal of the moving picture may be outputted.

When any one of the divided regions is focused, the control unit 160 can control the focused region to be visually identified. In FIG. 6A, the border 610 and the broadcast information 620 of the solid line (the first area I) are outputted in the focused area, thereby indicating that the focused area is visually identified. Here, the broadcast information includes information such as the name of the broadcast program of the mosaic animation outputted in the focused area, the broadcast time, and the like, and can be used to help the user understand the mosaic animation output using the broadcast information. The visual distinction example of the focused area shown in FIG. 6 (a) is for convenience of explanation and does not limit the present invention. In addition to the examples shown, the focused areas can be visually distinguished and displayed in a variety of ways that can be devised by those skilled in the art.

The control unit 160 may change the focusing area based on the user input. For example, when a user input for focusing the second area II is received, the controller 160 controls the second area II in the first area I, as in the example shown in FIG. 6 (b) ), And to control the audio signal in the second area II to be output. The controller 160 fades out the audio signal in the area to be focused out and the audio signal in the area to be focused is fade out in.

The particular user input received while focusing a particular area may be applied only to that particular area. 6 (b), when the channel change input is received from the user while the second region II is being focused, the control unit 160 controls the first, third, and fourth regions (for example, I, III, and IV), the broadcast channel can be controlled to change only in the second region II. Accordingly, as in the example shown in FIG. 6 (c), the Mosaic video of the changed broadcast channel can be output to the second area II.

When the broadcast channel of the focused area is changed, if the broadcast channel to be changed is the same as the broadcast channel of the mosaic broadcast signal output from the other area, the control unit 160 skips the broadcast channel to be changed, Or to automatically change focusing to an area where a broadcast signal for a mosaic of the same broadcast channel as the broadcast channel to be changed is output.

For example, when the broadcast channel of the second area II shown in FIG. 6C is changed to 12, since the broadcast channel 12 is already displayed through the third area III, The control unit 160 may control the broadcast channel of the second area II to be changed to 13 or to automatically change the focusing position to the third area III.

When the focused area is selected, the controller 160 stops dividing the output image and controls the moving image for the channel having the same broadcast channel as the mosaic image output from the selected area to be displayed on the full screen.

For example, when the user selects the second area II in FIG. 6C, the controller 160 may generate a broadcast channel (i.e., Ch. 11) that is the same as the mosaic movie output in the second area II, Can be controlled so that the moving image for the channel of the " channel "

The focus movement between divided areas can be realized by the direction key operation of the remote controller, but is not limited thereto. The control unit 160 may control the focus of the divided regions to be moved using the motion information received by the remote control receiving unit 150 from the remote controller. A detailed description thereof will be made with reference to FIG.

Fig. 7 is an exemplary diagram for explaining the movement of focus between regions divided by motion information. Fig. When the focus between regions divided by the motion information is moved, the control unit 160 controls the motion of the user on the output screen to be output through the screen output unit 140, as in the example shown in FIG. 7 (a) It is possible to control the moving cursor 710 to be displayed. By displaying the cursor 710, it is possible to help the user who moves the remote control to understand the movement of the remote control.

The control unit 160 may control the focus to move to the area designated by the cursor 710 while moving the cursor 710 along the motion of the user. For example, when the cursor 710 moves from the first area I to the second area II, the controller 160 controls the first area I as in the example shown in FIG. 7 (b) To the second area (II).

The broadcast receiving apparatus 200 according to an exemplary embodiment of the present invention may control the genre to match a specific genre for each divided region when the output screen output through the screen output unit 140 is divided into a plurality of regions.

For example, the first area is assigned to the drama, the second area to the sports, the third area to the movie, and the fourth area to the entertainment program, and in each area, the mosaic video of the broadcasting channel for outputting the broadcasting program to the genre is output can do. Furthermore, when the channel is changed in each area, it is possible to control so that the Mosaic video of another broadcast channel outputting a broadcast program of the same genre is output by channel change. For example, in a state where the second area is focused, when the channel change input is received, the controller 160 controls to output a Mosaic video of another broadcast channel outputting a broadcast program of the sports genre corresponding to the channel change signal .

In the above-described embodiment, it is exemplified that a plurality of divided regions output mosaic videos. However, a plurality of divided regions do not necessarily output a mosaic video. According to another example of the present invention, a Video On Demand (VOD) and an application execution screen may be executed through at least one of the plurality of divided regions. While the mosaic video is displayed in the first area, an application execution screen may be displayed in the second area, a video promised by the user or a video recommended by the on-demand video server, a third area and a fourth area. If a web browser is executed as an application, a received web page may be displayed by connecting to a predetermined URL address through at least one of the divided regions.

The control unit 160 may output the most purchased video or its publicity video provided by the video-on-demand server, or may control the output of the most downloaded application or its installation page from the application management server. As another example, the controller 160 may analyze the usage pattern of the user, and may control the video to be output in any one of the user-watched video most watched by the user or the user's most used area. That is, the control unit 160 may analyze the usage pattern of the user to control the personalized screen to be configured.

According to an embodiment of the present invention, the kind of data displayed through the divided areas can be preset by user setting, and a plurality of combination sets may be predetermined. For example, a mosaic movie is output through two of the four areas, and a first set is set to output an on-demand movie in the two areas. The mosaic movie is outputted through the two areas, If the second set is set to output an application execution screen, the control unit 160 may change the screen configuration depending on whether the first set or the second set is selected. If a change to the second set is requested while the first set of screen configurations are being displayed, the controller 160 may control the two areas that output the video on demand to output the execution screen of the application.

It is needless to say that a preset set can be created in various combinations other than the listed ones, and a set can be configured for each type of data. For example, the first set may be set to output the mosaic video through all four regions, and the second set may be set to output video on demand through all four regions. As another example, the first set may include a mosaic video of a channel previously registered by a user as a preferred channel, a set 2 of four recommended VODs of an on-demand video provider, a third set of mosaic videos of four channels having the highest rating May be set.

According to one embodiment of the present invention, the above-described method (operation flow diagram) can be implemented as a code that can be read by a processor on a medium on which the program is recorded. Examples of the medium that can be read by the processor include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, etc., and may be implemented in the form of a carrier wave (e.g., transmission over the Internet) .
