<p>At a storage section 11, picture information of intermediate resolution and picture information of low resolution are formed on the basis of picture information of high resolution which has been read out from a frame memory 3. These picture information are caused to undergo fixed length encoding at a compression/expansion circuit 20. These picture data of three kinds of resolutions which have been caused to undergo fixed length encoding are respectively recorded, in order of reproduction (playback) and continuously, onto an optical disc having tri-sected recording areas for respective resolutions.
Thus, it is sufficient to read out, from anyone of the recording areas, picture data of resolution corresponding to equipment which outputs picture data. In addition, since the picture data of respective resolutions are recorded in order of reproduction (playback) and continuously, the seek time is eliminated, thereby contributing to realization of high reproduction (playback) speed.</p> |
