<p>PURPOSE: To decode a video signal corresponding to plural encoding systems by separating a data sequence received by an interface circuit, transferring the information of a decoding method to a memory and transferring encoded data to a decoding processing circuit. CONSTITUTION: This device is composed of a main processor 3, ROM 1 memory 2, video output control circuit 4, output device 5, voice output control circuit 6, voice output device 7, decoding processing circuit 9 and voice decoding processing circuit 10. The image decoding processing circuit 9 is composed of a decoding program storage memory C, image decoding processor B and memory A. The voice decoding processing circuit 10 is composed of a decoding program memory F, voice decoding processor E and memory D. Since encoded data and decoding program are received from a communication line, at a single decoding terminal, the encoded data can be decoded corresponding to the plural encoding systems without previously storing any decoding program required for decoding.</p> |
