On a 10-bit coding profile for AVS2 standard

Abstract

AVS2 is an ongoing standardization effort by Audio Video coding Standard Workgroup of China toward high efficiency coding of multimedia compared to the previous standard (AVS1). AVS2-P2 is the video part for high-definition, ultra-high-definition and three dimensional video contents. Raw video content of 10-bit bit depth has superior visual quality compared to traditional 8-bit counterpart. Thanks to the advance of computing power of hardware, support for video content of 10-bit bit depth is becoming very important in current high resolution video processing applications. We present here a new 10-bit design to AVS2-P2 standard based on our 10-bit encoding proposal [1] on the 48th AVS2 working group meeting.
