VIDEO INFORMATION RECORDING APPARATUS AND REPRODUCING APPARATUS

摘要

A method for recording video information for controlling video information copy limit information when copying data recorded on a recording medium to another recording medium. By detecting copy limit information (CCI) or a watermark (WM) of an AV stream to be input, it is checked whether the content of the copy limit information or the watermark has been changed. Change point information of the copy limit information or the watermark and the content of the copy limit information or the watermark are fetched. According to the change point information fetched, control information is generated for controlling the copy limit information. When the input signal has ended, a code for preventing altering is calculated, it is confirmed that the copy limit information or the watermark has not been altered, and the control information generated is recorded together with the video information to the recording medium of copy destination.
