Here, the client manager 202 can request downloading of a broadcast schedule to the schedule server 132, for example, when the content player is activated according to a user operation, The client manager can request the scheduled download of the schedule to the schedule server 132 when the content player reaches a specific scheduled time while the content player is being activated.

The schedule information includes a default schedule to prevent a broadcast accident due to omission of schedule information. If there is no broadcast content at the corresponding time in the newly created schedule, or if normal schedule play is impossible due to the failure, the default schedule So that the broadcast is switched.

Next, the content downloader 204 requests the video file included in the schedule (broadcast schedule) to the download server 134 in the data media system 130 according to an instruction from the client manager 202, And receiving the moving picture file downloaded (received) from the download server 134 and delivering it to the player manager 206. Here, broadcast data such as a moving picture file may be data to which DRM (Digital Rights Management) is applied.

At this time, the content downloader 204 transmits a data delimiter such as a movie file extracted through the analysis of the schedule provided from the client manager 202 to the download server 134 to request a download of a movie file or the like, And may request the download server 134 to download data such as a moving picture file when the preset reservation time (for example, a morning time zone in which communication traffic frequently occurs).

Then, the player manager 206 generates a control command for requesting a schedule, transfers it to the client manager 202 (request control of the schedule), and transmits the schedule information delivered from the client manager 202 according to the request control of the schedule Stores the data in a schedule data DB 208, stores data such as a moving picture file delivered from the content downloader 204 in accordance with a broadcasting schedule in a schedule data DB 208, generates a control command for screen switching and control To the content viewer 214, and the like.

To this end, the schedule data DB 208 may store schedule information, broadcast data such as a moving picture file, real-time data of the information TR, and the like.

Next, the socket module 210 requests real-time data for the information TR (TR data) to the information server 136 in the data media system 130 in accordance with a control command from the schedule handler 212, And receiving real-time data of the information TR downloaded (received) through the socket communication from the information server 136 in response to the request, and delivering it to the schedule handler 212. Here, the socket module 210 may convert real-time data of the information TR downloaded from the information server 136 into a JavaScript Object Notation (JSON) format and transmit the converted data to the schedule handler 212.

Meanwhile, the schedule handler 212 generates a control command for requesting the information TR and transfers the control command to the socket module 210 (request control of the information TR), and the information TR The real-time data of the relevant information TR corresponding to the necessary time point (display time of the broadcast data) for each screen from the schedule data DB 208, (Display on the screen) by the display unit 214 as shown in FIG.

Here, the schedule handler 212 stores the corresponding video file (broadcast) stored in the schedule data DB 208 when the display of the video file, the information TR, and the like is completed (that is, the withdrawal to the content viewer 214) Data) or information TR can be automatically deleted.

The content viewer 214 may refer to a screen browser driver or the like linked with the player manager 206 and the schedule handler 212. The content viewer 214 may display the information TR delivered from the schedule handler 212 on a screen (Display) by mapping to a predefined position, or to display (display) broadcast data such as a moving picture file transmitted from the schedule handler 212 on the entire screen or a predetermined position of a divided partial screen Can be provided.

Next, a series of processes for providing a broadcast service control using a broadcast schedule to a client using the broadcast service control apparatus of the present invention having the above-described configuration will be described.

3 is a flowchart illustrating a main process of realizing broadcast service control based on schedule information according to the present invention.

3, when a user activates a content player loaded on a client (step 302), the client manager 202 determines whether or not the content player has been loaded on the client, based on a control command from the player manager 206 (Schedule schedule information) to the schedule server 132 in the data media system 130 (step 304). Here, the content player may be a player in which the client 110 is downloaded from the data media system 130 and stored in an internal memory (not shown).

Next, when the schedule information is received from the schedule server 132 in the data media system 130 in response to the download request of the schedule information, the client manager 202 delivers the schedule information to the player manager 206, The manager 206 stores the schedule information in the schedule data DB 208 (step 306).

Then, the schedule handler 212 analyzes the schedule information stored in the schedule data DB 208 to generate a control command for downloading the information TR (TR data) for buffering the next schedule screen according to the schedule information, In response, the socket module 210 requests the information server 136 in the data media system 130 to download the information TR (step 308).

The information TR downloaded from the information server 136 in the data media system 130 is converted into the JSON format through the socket module 210 and stored in the schedule data DB 208 via the schedule handler 212 Step 310).

Next, the schedule handler 212 fetches the relevant information TR necessary at a necessary time for each screen on the basis of the schedule information from the schedule data DB 208 and transfers it to the content viewer 214. As a result, , The information TR transmitted from the schedule handler 212 is mapped to a predefined position on a screen (not shown) and displayed (step 312). At this time, the related information TR drawn out by the schedule handler 212 and displayed on the screen can be automatically deleted from the schedule data DB 208 at the same time of the withdrawal.

On the other hand, the schedule handler 212 monitors whether or not an off operation (or a reservation off operation previously set by the user) for the activation (operation) of the content player is input according to user operations or the like (step 314) If it is determined that the off-operation of the content player has been input, the schedule handler 212 terminates the activation of the content player (step 316). That is, the client 110 switches the content player from the startup mode to the standby mode.

4 is a flowchart illustrating a main process of downloading and displaying broadcast data of a moving picture according to the present invention.

4, when the client 110 is executing the standby mode or the startup mode (step 402), the content downloader 204 checks the current time and determines that the current time is a preset time (for example, A morning time zone during which communication traffic does not frequently occur) (step 404).

As a result of the determination in step 404, if the current time is the predetermined reservation time, the content downloader 204 analyzes the schedule information provided from the client manager 202 (step 406) (Step 408). The data separator of the extracted moving picture file is transmitted to the download server 134 in the data media system 130 together with the download request message to request download of the related broadcast data (step 410) .

Next, the broadcast data (movie file, etc.) downloaded from the download server 134 is transferred to the player manager 206 via the content downloader 204, and stored in the schedule data DB 208 (step 412). Here, the broadcast data may be DRM-applied data.

Thereafter, the schedule handler 212 monitors the schedule information (step 414) and determines whether or not the present time (time) is the broadcast time of the broadcast data (video file, etc.) The schedule handler 212 retrieves the corresponding broadcast data from the schedule data DB 208 and outputs the retrieved broadcast data to the content viewer (step 416) 214, and as a result, related broadcast data is displayed (displayed) on the screen (step 418).

The schedule handler 212 checks whether or not the broadcast data has been completely displayed (step 420). If it is determined that the screen display of the corresponding broadcast data is completed as a result of the check here, the schedule handler 212 notifies the schedule data DB 208 (Step 422). ≪ / RTI >
