Abstract:
1. A data processing apparatus for outputting a plurality of picture data forming reproduced data to a reproduction apparatus for reproduction, said data processing apparatus comprising: a processing circuit which judges whether a reproduction rate of said picture data by said reproduction apparatus is slower than a transfer rate for transferring said picture data to said reproduction apparatus and outputs all of the picture data forming said reproduced data to said reproduction apparatus when said processing circuit judges that said reproduction rate is slower than said transfer rate, and if said processing circuit judges that said reproduction rate is faster than said transfer rate, said processing circuit outputs to said reproduction apparatus less than all of said picture data forming said reproduced data able to be transferred at said transfer rate in accordance with said reproduction rate among all of the plurality of picture data forming said reproduced data, wherein in response to a command to change from a first reproduction rate faster than said transfer rate to a second reproduction rate slower than said transfer rate received by the processing circuit, said processing circuit outputs to said reproduction apparatus data other than picture data already written in an input memory of said reproduction apparatus in the picture data forming said reproduced data including picture data being reproduced, and causes said reproduction apparatus to reproduce said reproduced data at said second reproduction rate when the output of said data other than picture data already written in said input memory is enough for reproduction of a next picture data in the picture data being reproduced, and if the output of said data other than picture data already written in said input memory is not enough for reproduction of the next picture data in the picture data being reproduced, said processing circuit causes said reproduction apparatus to reproduce said reproduced data at said second reproduction rate when said output is ended.
