Abstract: For a stream input from a signal input section to a synchronization word analysis section, a synchronization word is searched by the synchronization word analysis section and it is confirmed whether or not the analyzed synchronization word matches a pattern of a decodable synchronization word. When a synchronization word is detected, the synchronization word is selectively output to a header analysis section corresponding to the type of the detected synchronization word by decoding system switching section. Then, using analyzed header information, a frame is decoded by the decoding section and output from a signal output section. After the frame is output, the process returns to the synchronization word analysis section and the same processing is performed to each of all frames in the stream.
