A mobile terminal and method of controlling a broadcast in a mobile terminal are provided, by which whether to update channel/program relevant data is determined by checking a presence or absence of modification of previously stored channel/program relevant data in a simple manner. The present invention includes a memory storing channel/program relevant data, a wireless communication unit receiving first channel/program relevant data, and a controller determining whether the received first channel/program relevant data matches first channel/program relevant data stored in the memory, controlling the wireless communication unit to receive entire channel/program relevant data if the received first channel/program relevant data does not match the stored first channel/program relevant data, and updating the stored first channel/program relevant data with reference to the received entire channel/program relevant data.
