Abstract:
A high resolution video signal is divided by video division means into a main signal and a sub signal, and the main signal and the sub signal are MPEG-encoded. The stream of the main signal and the stream of the sub signal are divided into 1 GPO or more of frames. First interleave blocks each including 1 GOP or more of the stream of the main signal and second interleave blocks each including 1 GOP or more of the stream of the sub signal are recorded on an optical disk. A high resolution reproduction apparatus reproduces both the first and second interleave blocks to obtain a high resolution video output. A non-high quality picture reproduction apparatus reproduces only the first or second interleave blocks to obtain a standard resolution video output.
