Abstract:
1. A method for roaming with broadcast program information in a broadcast terminal relocating from a first region to a second region, the method comprising: receiving, at the broadcast terminal, a metadata interface for a broadcast program information data conversion; storing the received metadata interface in an internal memory of the broadcast terminal; receiving, at the broadcast terminal, broadcast data and broadcast program information data, wherein the received broadcast program information data comprises data that corresponds to the second region and is not in a Global Listing Format; determining, at the broadcast terminal, whether a schema of the received broadcast program information data satisfies a specific condition capable of being processed by the broadcast terminal; displaying, at the broadcast terminal, the received broadcast data upon determining that the schema of the received broadcast program information data satisfies the specific condition; reading, at the broadcast terminal, the stored metadata interface upon determining that the schema of the received broadcast program information data does not satisfy the specific condition; and converting, at the broadcast terminal, the schema of the received broadcast program information data into another schema capable of being processed by the broadcast terminal using the read metadata interface, wherein converting the schema of the received broadcast program information data into the another schema comprises mapping a schema structure of the second region to a schema structure of the first region based on meanings of schema of the first region and on meanings of schema of the second region, irrespective of any differences between the schema structure of the first region and the schema structure of the second region.
