DEVICE AND METHOD FOR RECORDING AND REPRODUCING INFORMATION WITH MATCHING PROCESSING FUNCTION OF ASPECT RATIO INFORMATION

摘要

PROBLEM TO BE SOLVED: To prevent the malfunction of equipment by obtaining a match between the content of aspect ratio information to be described in a prescribed area (RDI) regulated by a DVD format and the content of the aspect ratio information to be described in a prescribed area (sequence header) regulated by an MPEG- PES format with respect to the content of the aspect ratio information included in an inputted source. SOLUTION: The aspect ratio information of an inputted video signal is detected and rewritten so as to obtain a match between the content of the aspect ratio information, the content of the aspect ratio information of the RDI positioned at the head of a video object unit(VOBU) and the content of the aspect ratio control information of the sequence header of compressed video data within the VOBU to which the RDI belongs.
