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).
