ABSTRACT:
Contents reserved to be recorded by a user manually operating a switch unit are stored in an EPG/reservation information memory as first reservation information. A CPU having acquired EPG data by a TV unit or a communication interface stores the acquired EPG data in the memory. By referring to the stored EPG data, program information corresponding to the stored first reservation information is extracted, and an ID of the extracted program information is added to the first reservation information. Therefore, the subsequent change of a broadcast schedule is made by referring to the EPG data to be acquired later. Even if a manual reservation is made, the user can reliably view or record a program desired to be reserved.
