Abstract: Television images originate from many sources, including video cameras, motion-picture film, and digital still graphics. This article describes how future all-digital high-definition television (HDTV) transmission systems and NTSC receivers can be designed to adapt to the frame rate, aspect ratio, color mode, and resolution of the signal source in a simple and cost-effective manner. This can provide improved picture quality or reduced transmission bandwidth requirements for image segments from certain sources. In HDTV transmission systems, the transmission coder operates at the source frame rate, for example, 24 frames/sec for film sources. The receiver frame store performs frame-rate conversion for the display. In high-end receivers, this processing can reuse the motion vectors transmitted by the HDTV coder. In NTSC receivers incorporating field stores and progressive scan displays, source-adaptive processing allows perfect interlace to progressive scan conversion and luminance/chrominance decoding for still images, and improved decoding of images from motion-picture film. To make these methods more efficient, “origination-source ID” data is incorporated into the video signal during post-production.
