Abstract

A mobile communication terminal equipped with a broadcast program information roaming function and a roaming method for use in the same are disclosed. The mobile communication terminal equipped with a broadcast program information roaming function includes: a Radio Frequency (RF) receiver for receiving information of a metadata interface for broadcast program information conversion from a broadcast program information mapping service provider, and receiving broadcast program information from a broadcast transmitter; a memory for storing the information of the metadata interface for the broadcast program information conversion; and a controller for analyzing the received broadcast program information, and converting the broadcast program information into a schema of a roaming region using the metadata interface for the broadcast program information conversion.

Claims

1. A method for roaming with broadcast program information comprising the steps of:

a) receiving broadcast program information data;

b) determining whether a schema of the received broadcast program information data satisfies a specific condition capable of being processed by a broadcast terminal, and

c) if the schema of the broadcast program information data does not satisfy the specific condition, converting current schema data into another schema data capable of being processed by the broadcast terminal using a metadata interface for conversion of the broadcast program information.

2. The method according to claim 1, wherein the metadata interface for the broadcast program information conversion is indicative of data pre-received in the broadcast terminal.

3. The method according to claim 2, wherein the metadata interface for the broadcast program information conversion is received from a broadcast program information mapping service provider over a mobile communication network.

4. The method according to claim 1, wherein the metadata interface for the broadcast program information conversion is received from a broadcast program information mapping service provider over the Internet.

5. The method according to claim 1, wherein the specific condition capable of being processed by the broadcast terminal is executed when a schema structure of the received broadcast program information is different from that of pre-stored broadcast program information.

6. The method according to claim 1r wherein the specific condition capable of being processed by the broadcast terminal is executed when language of the received broadcast program information is different from that of pre-stored broadcast program information.

7. A mobile communication terminal equipped with a broadcast program information roaming function, comprising:

a Radio Frequency (RF) receiver for receiving information of a metadata interface for broadcast program information conversion from a broadcast program information mapping service provider, and receiving broadcast program information from a broadcast transmitter;

a memory for storing the information of the metadata interface for the broadcast program information conversion; and

a controller for analyzing the received broadcast program information, and converting the broadcast program information into a schema of a roaming region using the metadata interface for the broadcast program information conversion.

8. The mobile communication terminal according to claim 7, wherein the controller, if a schema structure of the received broadcast program information is different from that of pre-stored broadcast program information, converts current schema data into another schema data capable of being processed by the terminal.

10. The mobile communication terminal according to claim 7, wherein the metadata interface for the broadcast program information conversion is received over a mobile communication network.

11. The mobile communication terminal according to claim 7;

wherein the metadata interface for the broadcast program information conversion is received over the Internet.

9. The mobile communication terminal according to claim 71 wherein the controller, if language of the received broadcast program information is different from that of pre-stored broadcast program information, converts current schema data into another schema data capable of being processed by the terminal.
