Keeping video quality pristine throughout the production process – introducing 10-bit 4:2:2 AVC/H.264 encoding

Yasser Syed (ATEME, USA)

With worldwide growth in the take up of HDTV and digital cinema there is a growing need across the industry for production and contribution applications with higher standards of video quality. The de-facto standard for professional video is 4:2:2 10-bit because it is the way it is captured and transmitted over SDI (Serial Digital Interface). The entire production chain (film scan, video edition, archiving etc.) uses at least 10-bit signals. But when it comes to broadcast contribution, encoders and decoders are still limited to 8-bit, usually with 4:2:0 chroma sub sampling, just as with consumer video. The result is that when transmitting video from one point to another, picture information can get lost and quality can suffer. Maintaining the encoding and decoding stages at 10 bits increases overall picture quality, even when scaled up 8-bit source video is used. 10-bit video processing improves low textured areas and significantly reduces contouring artifacts. This paper will demonstrate the advantages of processing video in its native SDI format using AVC/H.264 4:2:2 10-bit encoding. It will include and discuss results that were obtained from ATEME current real-time HD encoders and from bit-accurate software models of upcoming real-time products. Comparisons will be made over a very wide range of bit-rates in order to illustrate the achieved gains within a great variety of applications.
