Broadcast receiving apparatus

摘要

A broadcast receiving apparatus (2100) performs descrambling implicitly during the access of scrambled information within a broadcast signal by a program. The broadcast receiving apparatus (2100) in the present invention includes a descrambler (2104) operable to perform descrambling on a per-piece of information basis. Together with executing a service including one or more pieces of information, the broadcast receiving apparatus (2100) adds a service to be executed, cancels a service to be executed, and controls descrambling of one or more pieces of information using the descrambler (2104).
