Images and videos can be output to be displayed.

4 and 5 are diagrams for explaining a broadcast situation method according to an embodiment of the present invention. Specifically, FIGS. 4 and 5 are examples of screens S1 and S2 output to the TV 10 according to an embodiment of the present invention.

As shown in FIG. 4 , data broadcasting (currently broadcasting data broadcasting) that is broadcast in real time may be displayed on a partial area A4 of the TV screen S1 . The currently broadcast data broadcast may be a broadcast corresponding to broadcast data received from the content providing server 40 according to a broadcast schedule. The currently broadcasting data broadcasting can be understood as a one-way transmission broadcasting in which the viewer cannot directly control such as fast forward, rewind, and skip (skip). An application screen corresponding to the application screen data generated by the media providing server 50 may be displayed in the remaining area A1 of the screen S1 except for a partial area A4 in which a video is displayed.

For example, the remaining area A1 may include icons A11, A12, A13, and A14 that can be shortcuts to various functions. The user can select one of A11, A12, A13, and A14 by using a remote control for TV broadcasting, and in response to the selection input, Home (A11), Today's TV (A12), My Home, where currently broadcasting data broadcasting is in progress, Other pages such as necessities (A13), new spring sports competition (A14), shopping, and the like are displayed on the screen of the TV (10). Today's TV (A12), my house necessities (A13), spring new sports competition (A14), and shopping pages may be obtained through the media providing server 50 and output to the TV.

The application screen may include, for example, a search icon (A2) and an order icon (A3). In response to a selection input for the search icon A2 or the order icon A3 , a schedule and a search page or an order page may be output.

In a situation where the currently broadcasting data broadcast (movie) is displayed in the partial area A4, guide information may be displayed in the form of a pop-up PU. 4 shows that guide information on discount benefits and accumulation benefits is displayed in the form of a pop-up (PU). In such a situation, if there is no selection/input from the user within a preset time, the corresponding pop-up PU disappears. If the user selects "OK" using a remote control for TV broadcasting, such a change signal is transmitted to the media providing server 50 through the set-top box 20 .

When the media providing server 50 receives such a change signal as described above, it goes through a step (S120) of confirming the broadcast schedule information. This is the same as described above. When the media providing server 50 receives the broadcast schedule information from the data server 60 (S120), it generates application screen data using it (S130). As described above, the application screen data is data on an application screen to be implemented (eg, displayed) on the screen of the TV 10 . FIG. 5 exemplarily shows a TV screen S2 implemented in the TV 10 after the media providing server 50 confirms the broadcast schedule information, and the generated application screen is transmitted to the set-top box 20 .

As shown in FIG. 5 , on the TV screen S2 , it can be confirmed that the “Today’s TV” tab is selected instead of the “Home” tab where data broadcasting (currently broadcasting data broadcasting) that is broadcast in real time is displayed. . In some area A4, a moving picture of a product in the currently broadcasting data broadcast may be continuously displayed, and in another partial area A6, information about the product and a price to which a discount is applied may be displayed. In particular, since the media providing server 50 receives the broadcast schedule information from the data server 60 and uses it to generate application screen data, the item to be broadcast later according to the broadcast schedule information is located at the bottom of the TV screen S2. A part of the screen and part of information (including broadcast time, etc.) can be displayed. Accordingly, it is possible to provide an environment in which the user can directly watch a video of the corresponding product in an on demand format (regardless of broadcast time) by selecting another product using a remote control or the like.

As shown in FIG. 4 , when the "Home" tab is selected and the data broadcast broadcast in real time is displayed on a partial area A4 of the TV screen S1, the user rewinds the video to watch it or fast-forward to watch it. You cannot use search functions such as However, as shown in FIG. 5 , when another tab such as the “Today’s TV” tab is selected, the user selects the “Return video” icon A5 and uses the search function to find the information the user wants in the video. can be easily found in

For reference, FIG. 4 shows that, in a situation where currently broadcasting data broadcasting (movie) is displayed in a partial area A4, guide information on discount benefits and savings benefits is displayed in the form of a pop-up (PU). However, the present invention is not limited thereto. For example, when the user clicks a specific button on the remote control or selects a specific button in the TV screen S1, the click and/or selection may be processed as a change signal transmitted to the media providing server 50.

On the other hand, as shown in FIG. 4 , in a situation where the currently broadcasting data broadcast (movie) is displayed in the partial area A4, the media providing server 50 receives the change signal from the set-top box 20, and as a result, FIG. When a screen such as the one shown in 5 is displayed on the TV 10, the moving picture displayed in the partial area A4 in FIG. 5 is a moving picture connected to the moving picture displayed in the partial area A4 in FIG. can make it happen For example, the first image frame of the moving picture displayed in the partial area A4 in FIG. 5 is an image frame of the moving picture displayed in the partial area A4 in FIG. 4 when the media providing server 50 receives the change signal, or It may be an image frame immediately after it.

Through this, even if the configuration of the screen of the TV 10 is changed, the user can watch the introduction video about a specific product without interruption. That is, when switching from the TV screen S1 as shown in FIG. 4 to the TV screen S2 as shown in FIG. 5 , even if a moving picture for the same product is played, the TV screen as shown in FIG. 5 . After the transition to ( S2 ), a moving picture following the moving picture on the TV screen S1 as shown in FIG. 4 may be played instead of being played from the beginning of the corresponding moving picture.
