It is contrasted with the retroactively-named standard dynamic range (SDR).

Scaling them up to HD resolution with a 16:9 aspect ratio presents a number of challenges. First is the potential for distracting motion artifacts due to interlaced video content.

In addition, black and white receivers could take the Y′ signal and ignore the U- and V-color signals, making Y′UV backward-compatible with all ...
