A data processing apparatus has: a decoding interval detecting unit detecting a second interval according to coding order of frames necessary to decode a first interval which is designated by display order of the frames in video data which has been compression-encoded by using an inter-frame compression according to a predictive coding; and a file forming unit forming a file to store the video data in the second interval detected by the decoding interval detecting unit. The file forming unit adds information showing the first interval by the frame display order to the file.

An AV data input/output controlling circuit is connected through a data bus to a synchronous-asynchronous conversion circuit and through a control bus to a recording and reproduction controlling circuit. The AV data input/output controlling circuit inputs and outputs audio and/or video data of a normal data rate. The AV data input/output controlling circuit also inputs and outputs audio and/or video data of a higher data rate than usual. In the data recording and reproducing apparatus, audio and/or video data is transferred through a data bus synchronized with a reference synchronization signal S etc., the audio and/or video data input from an external unit is recorded in a storage device, and the audio and/or video data recorded in the storage device is reproduced and supplied to the outside.
