VIDEO AND AUDIO SIGNAL PROCESSOR AND AUDIO SIGNAL PROCESSOR

摘要

A video and audio signal processor is provided with a signal receiving means which receives input signals that includes encoded audio signals and encoded video signals and can be delimited in a prescribed unit and outputs the encoded audio signals and encoded video signals by separating the encoded audio and video signals from the input signals, an audio signal processing means which processes the encoded audio signals in a prescribed way and outputs the processed signals as audio signals, a video signal extracting means which extracts prescribed frames from the encoded video signals outputted from the signal receiving means and outputs the frames as a representative video signal, and a video signal processing means which processes the representative video signal outputted from the video signal extracting means in a prescribed way and outputs the representative video signal as video signals.
