Abstract
In decoding a data signal that is associated with a compressed video signal and a compressed audio signal in digital broadcast and is multiplexed in digital broadcast, a digital broadcast receiver according to the present invention efficiently decodes the data signal when the data signal includes a compressed video signal or a compressed audio signal and the compression method used for the compressed video signal or the compressed audio signal is the same as that used for the compressed video signal or the compressed audio signal multiplexed in the digital broadcast. The data signal separated by a demultiplexer is stored in a data decoder in a memory . A CPU analyzes the stored data signal and stores the data signal analyzed by the CPU in a decoder buffer when the analyzed data signal includes a compressed video signal or a compressed audio signal and the compression method used for the compressed video signal or the compressed audio signal is the same as that used for the compressed video signal or the compressed audio signal multiplexed in the digital broadcast signal.
