Such memory 184 includes the concept of a generally known hard disk, card type memory (e.g., SD or XD memory), flash memory, RAM, ROM, and the like.

The broadcast receiving module 185 receives broadcast signals transmitted through satellite or terrestrial waves and converts the received broadcast signals into broadcast data types that can be output to the sound output units 114 and 131 and the display unit 113 and outputs the broadcast data formats to the controller 180. In addition, the broadcast receiving module 185 receives additional data (e.g., EPG (Electric Program Guide), channel list, etc.) related to broadcasting. The broadcast data and the additional data converted by the broadcast receiving module 185 may be stored in the memory 184. [

The power supply unit 127 receives external power and internal power under the control of the controller 180 and supplies power necessary for operation of the respective components.
