MPEG video decoder

摘要

A picture decoding section (12) starts to decode a bit-stream for one picture when a decoding start command (22) is supplied from a decoding start command generating section (14), and outputs a decoding completion command (23) when the decoding is completed. Decoded picture data is stored in a decoding frame buffer (13). The decoding frame buffer (13) outputs a bufferfull notification (24) when a certain quantity of picture data is stored. The decoding start command generating section (14) outputs the decoding start command (22) to the picture decoding section (22) when a decoding completion command (23) is outputted from the picture decoding section (12) and the bufferfull notification (24) is not outputted from the decoding frame buffer (13).
