ABSTRACT:
A video receiver including an interface to which compressed and encoded video-audio data is supplied from a transmission line and stored in the receiver, a decoder for decoding the video-audio data retrieved from storage, a monitor for connecting to the decoder and a CPU for controlling data processing. A common buffer memory for temporarily storing the video-audio data is provided between the interface and the decoder and between the interface and the storage device and, while the video-audio data is being received, access to the buffer memory is subjected to time-shared, exclusive control by the CPU in synchronism with the clock frequency of the transmission line, whereby video data is read out of the buffer memory by the decoder in parallel with the storage of the video-audio data, and is thereby decoded so that a picture is viewed on the monitor.
