Abstract:
A MPEG video decoder comprising:a picture decoding section for starting a decoding of a MPEG bit-streams as picture data for the predetermined number of pictures in response to a decoding start command, and outputting a decoding completion notification when the decoding of the bit-stream for said predetermined number of pictures is completed; a decoding frame buffer for sequentially storing the picture data decoded by said picture decoding section and outputting a bufferfull notification when a predetermined quantity of picture data is stored; a decoding start command generating section for outputting said decoding start command when said decoding completion notification is outputted from said picture decoding section and said bufferfull notification is not outputted from said decoding frame buffer; and a picture data output section for transmitting said picture data stored in said decoding frame buffer to a display unit, wherein a first timing for the picture decoding section to start decoding is different than a second timing for the picture data output section to transmit.
