Abstract
In a digital broadcast receiving apparatus, a receiver receives video packets or audio packets configuring a program of digital broadcast. A selector selects a part of the video packets or the audio packets of each channel received by the receiver. A determination unit determines whether or not decoding of the part of the packets selected by the selector has been completed normally. A decision unit decides requirement for descramble processing of each channel based on the determination result of the determination unit.
