Abstract

See full text

A digital video signal has a frame rate and a resolution within a range of resolutions. If the resolution of the received digital video signal is in a lower resolution range then it is not compressed or if in a higher resolution range the video color data is compressed by a constant compression ratio. Frames of digital color samples are transmitted and frames of digital color samples are received at the same frame rate. The received compressed digital color samples are expanded by a constant expansion ratio when transmitted in a compressed format and not expanded if transmitted in the uncompressed video format. A digital video signal is output with a resolution the same as the resolution of the original digital video signal.
