OPTICAL DISC FOR HIGH RESOLUTION AND THREE-DIMENSIONAL IMAGE RECORDING, OPTICAL DISC REPRODUCING DEVICE, AND OPTICAL DISC RECORDING DEVICE |
摘要 |
In an optical disc on which image signals of high resolution are recorded and a system for reproducing thereof, compatibility with a conventional system for reproducing image signals of normal resolution is to be realized. Image signals of high resolution are divided into a main signal and an auxiliary signal by an image separating member, and a first interleave block (54) and a second interleave block (55) formed by dividing each MPEG-coded stream into groups of frames of one GOP or more are alternately recorded on an optical disc (1). In a reproducing device capable of handling high resolution, both the first and the second interleave blocks are reproduced, thus providing an image of high resolution. On the other hand, in a reproducing device incapable of handling high resolution, only one of the first and the second interleave blocks is reproduced, thus providing an image of normal resolution. |
