Abstract:
A decoding method for decoding a video image signal, comprising:separating at least one of streams of video image signal to be decoded from a multiplexed stream received therein, which contains a plurality of video image signals; selecting one stream including a video image signal to be assigned to a master video image signal, which will be assigned to a master stream from the multiplexed stream; regenerating a reference time and a system clock which are used in decoding of the video image signal to be assigned to the master video image signal, based on a reference time information contained in the master stream; regenerating a reference time used for decoding the separated video image signal through the use of the reference time information contained in the separated stream of the video image signal to be decoded and the regenerated system clock; generating a decode starting signal though the use of the regenerated system clock; storing the video image signal contained in the separated stream in an input buffer memory in parallel with the processing of the separating, the selecting, the regenerating the reference time and the system clock, the regenerating the reference time used for decoding and the generating; and starting a decoding of the video image signal stored in the input buffer memory by the decode starting signal.
