Abstract
A system is described in which an uncompressed video signal is recorded on a disk and reproduced by a disk player that is connected to a high-definition television (HDTV) processor. Although primarily intended for still picture reproduction, this system can generate a display command that adds false moving-picture effects to the reproduced image. Each still-picture frame consists of 1280*1024 active pixels. This system records the luminance signal Y and two color difference signals CW and CN as component codes. The sampling frequency is 49.68 MHz for signal Y, and 24.84 MHz for the color difference signals. These signals are quantized by 8-bit linear conversion. The reproducing system has frame memory capacity equivalent to 2048*2048 pixels, 3.2 times the quantity of data per frame. Each frame memory stores data that continues over two frames and also provides vertical frame scrolls. Since video data can be transmitted in both horizontal and vertical scanning directions, the picture can be switched from one frame to another, making a vertical or a horizontal wipe. The remaining video area of the frame memory can store split-screen data. >
