PROBLEM TO BE SOLVED: To provide the video signal decoding device which has no wait time and is improved in usability by instantaneously switching video when a viewer changes channels. SOLUTION: A 1st rate buffer 12 temporarily holds a transport stream received with a satellite wave, etc., and sends it out to both a TS temporarily holding means 15 and a PID processor 14 at a set bit rate TS. The TS holding means 15 has fixed storage capacity which is large enough to store at least one GOP of each channel, and holds a fixed amount of the latest GOP of each channel. When a PID selecting means 11 switches PID, the latest GOP held by the TS temporary holding means 15 is sent out to the PID processor 14 at the set bit rate through a 2nd rate buffer 13 to obtain data needed to decode the GOP of the channel after the switching from the head, so that video can be decoded even right after the switching. |
