ABSTRACT:
A recommended program search device includes a viewing history information acquiring block which acquires a viewing channel and a viewing time by the user for each area corresponding to a time division and stores viewing history information including the viewing channel and the viewing time that are associated with each area in the storage, a program information acquiring block which acquires scheduled broadcast program information, including program time information enabling calculation of a program start time and a program broadcast time for a scheduled broadcast program and channel information about the scheduled broadcast program, and a search block which determines a user's favorite program from the scheduled broadcast program on the basis of a result of comparison between the program time information and the channel information included in the scheduled broadcast program information and the viewing channel and the viewing time stored in the storage.
