Patent ID: 8280220

Claim:
A reproduction apparatus successively decoding and reproducing a plurality of picture data forming reproduced data, comprising: a reproduction memory, a decoder configured to decode said picture data, write decoding results in said reproduction memory, and reproduce and output said decoding results read from said reproduction memory, and a processing circuit configured to perform decoding scheduling for determining an order of making said decoder decode picture data belonging to a group of picture data in units of groups of picture data comprised of a predetermined plurality of said picture data, generate scheduling result data including decoding order data indicating said determined order and validity data indicating which of the plurality of said picture data is reproduced at a first reproduction rate, select said picture data to be processed in said order determined by said decoding scheduling based on said scheduling result data, and, conditional on said selected picture data being valid, make said decoder decode and reproduce and output said picture data and, in response to receiving a reproduction rate change command that changes the first reproduction rate to a second reproduction rate, change said validity data of said scheduling result data in accordance with the second reproduction rate, wherein when receiving said change command while decoding, reproducing and outputting a first group of picture data at the first reproduction rate, said processing circuit is configured to decode, reproduce, and output not yet processed picture data of said first group of picture data based on said changed validity data and the second reproduction rate.
