The 4 : 2 : 2 Profile, which is a new profile for the MPEG-2 video standard, is intended for applications that use high quality video applications. The 4 : 2 : 2 Profile at Main Level permits better color resolution, allows coding of all active video lines and can operate at a bit-rate up to 50 Mbps. This allows flexibility in choosing video quality and latency that are stecific to the needs of studio applications, such as multiple generation coding (repeated encoding and decoding), digital effects and digital distribution. This paper describes the outline of the 4 : 2 : 2 Profile and shows its performances through quality vernfication tests.
