This Recommended Practice defines constraints on the VC-2 video compression standard such that 10-bit high-definition video signals can be compressed to only occupy the bit rate of 8-bit standard definition signals. Specifically, it defines constraints for compressing interlaced source video having 1920 or 1440 pixels/line by 1080 lines/frame at 25 or 30/1.001 frames/s, or progressive source video having 1280 pixels/line by 720 lines/frame at 50 or 60/1.001 frames/s, using 4:2:2 sampling in all cases. It also defines an application-specific level value corresponding to these constraints.
