Image data regenerating apparatus

摘要

The present invention is intended to enable smooth reverse regeneration of image data while minimizing a large-sized and expensive configuration of an apparatus according to the present invention. Compression-coded image data recorded on an optical disc 1 is regenerated and stored in a ring buffer 5. Image data stored in the ring buffer 5 is decoded in a decoding part 20. A control circuit 21 controls to store the image data necessary for decoding in the ring buffer 5 in terms of, for example, one GOP and repeatedly read the image data from the ring buffer 5 when it is necessary for reverse regeneration if reverse regeneration is commanded.
