At this time, the mobile terminal can no longer receive a specific broadcast. In this case, the present invention is to provide a method for receiving the same broadcast as the broadcast received from another broadcaster.

Next, the concept of the digital broadcasting service according to the movement of the mobile terminal according to an embodiment of the present invention will be described.

1 is a conceptual diagram illustrating a concept of a digital broadcasting service method of a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 1, it is assumed that there are two or more broadcast providers that service digital broadcast, and each broadcaster has a service area.

Here, each broadcaster digitally broadcasts a plurality of contents provided by content providers to users through an allocated frequency band. One content provider may simultaneously provide the same content to multiple broadcasters.

In addition, the service area refers to a regional range in which the broadcaster can serve. Each service area may overlap some or all, and each service area may be completely independent of each other. For convenience of description, the service area of the first broadcaster is referred to as a first service area 10, and the service area of a second broadcaster is referred to as a second service area 20.

It is assumed that the mobile terminal 200 moves to the second service area 20 while receiving a specific broadcast (eg, news) in the first service area 10.

Then, the mobile terminal 200 may not receive a specific broadcast. In this case, in order to receive the received specific broadcast, the mobile terminal 200 accesses the common broadcast information server 100 through the mobile communication network 30.

The common broadcast information server 100 stores information of broadcasts serviced by each broadcaster. In particular, the common broadcast information server 100 stores common broadcast information that is information of common broadcasts serviced by different broadcasters. In this case, the common broadcast information is preferably linked to each other for the same content and stored.

The portable terminal 200 connected to the common broadcast information server 100 may search whether the same broadcast as the broadcast received in the first service area 10 is serviced in the second service area 20. In this case, when the same broadcast is serviced, information for receiving a corresponding broadcast from the common broadcast information server 100 may be received, and the same broadcast may be received as the broadcast received in the first service area 10 by using the same broadcast. .

Hereinafter, a schematic configuration of a mobile terminal 200 according to an embodiment of the present invention will be described. 2 is a view for explaining a schematic configuration of a mobile terminal 200 according to an embodiment of the present invention.

In particular, the data signal includes broadcast information data and the like. To this end, the broadcast signal processor 230 may include a module for converting the received broadcast signal into a baseband signal. In addition, the broadcast signal processor 230 may include a module for selecting a channel from the broadcast signal and extracting a broadcast signal corresponding to the selected channel under the control of the controller. In this case, in the case of DVB-H, a time slicing technique may be used. In addition, since the digital broadcast cannot be retransmitted when an error occurs because the digital broadcast is one-way communication, the broadcast signal processor 230 may include an error correction module that processes forward error correction (FEC).

In addition, the broadcast signal processor 230 may include a codec for separately outputting video, audio, and broadcast information data. Here, the broadcast information data may be an electronic program guide (EPG) or an electronic service guide (ESG) according to the digital broadcasting scheme (DMB, DVB-H). Hereinafter, the broadcast information data will be described as ESG, but the present invention is not limited thereto and can be applied to the DMB system.

That is, the control unit 280 controls the wireless communication unit 210 to access the common broadcast information server 100, and the same broadcast as the broadcast received in the step S301 by another broadcaster searched in the previous step S309. Search for service). On the other hand, if there is no other receivable broadcaster as a result of the search in step S305, the controller 280 proceeds to step S313 to end the broadcast.

As a result of the search in step S309, the controller 280 proceeds to step S315 if it is possible to receive the same broadcast in step S311. On the other hand, if it is impossible to receive the same broadcast, the controller 280 proceeds to step S313 to end the broadcast.

In step S315, the controller 280 receives the ESG from the broadcaster. Then, the controller 280 determines whether there is a viewing authority of the corresponding broadcast from the ESG in step S317. Here, the broadcast is the same broadcast as the broadcast played in step S301.

As a result of the determination in step S317, if the viewing authority exists, the control unit 280 proceeds to step S321 to receive the corresponding broadcast and play it back. Here, the broadcast is the same broadcast as the broadcast played in step S301. On the other hand, if it is determined in step S317 that there is no viewing authority, the controller 280 proceeds to step S319 to purchase the corresponding broadcast, receives the corresponding broadcast in step S321, and reproduces it.
