The copy-related information of an input video signal is detected and the copy control information of RDI located at the head of each video object unit and the scrambling control information described in the packet header of the video packets in the video object unit to which the RDI belongs are rewritten so as to coordinate the contents of the copy-related information, those of the copy control information and those of the scrambling control information.

Method of coordinately processing pieces of copy information and information recording/reproducing apparatus

An erase prohibition setting unit sets erase prohibition in accordance with an instruction. When the range is not set in units of cells of the current cell, the current cell is divided by a cell separator to set a sequence of advanced cells. A reconstruction part reconstructs management information for playing back the advanced cells and current cell, and appends erase prohibition information to the management information for playing back the advanced cells that belong to the range.

Digital recording system using variable recording rate

The aspect ratio information of an input video signal is detected and rewritten in such a way that the contents of the aspect ratio information of RDI located at the head of each video object unit and the contents of the aspect ratio information in the sequence header of the compressed video data in the VOBU to which the RDI belongs are coordinated.
