ABSTRACT:
In a digital broadcast receiving apparatus, digital broadcast signals provided by a digital broadcast method are supplied to various types of external units and are effectively utilized. In the above apparatus, a descrambler descrambles a transport stream output from a front end unit and supplies it to a digital interface and a demultiplexer. The demultiplexer extracts from the transport stream a compressed video signal and a compressed audio signal of a program specified by a user, and supplies the extracted signals to an MPEG decoder. The MPEG decoder decompresses the supplied video signal and the audio signal and supplies them to the digital interface, an NTSC encoder, and an audio signal D/A converter. The digital interface supplies either of the transport stream or the decompressed data to a digital external unit under the control of the controller.
