Paper Abstract

This paper describes a study to investigate possible ways to improve the VPX codecs in the context of both 8-bit SDR video and 10-bit HDR video content, for two types of applications: streaming and high quality (near lossless) coding for content contribution editing. For SDR content, the following tools are investigated: (a) lapped biorthogonal transforms for near lossless applications; and (b) optimized resampling filter pairs for adaptive resolution coding in streaming applications. For HDR content, a data adaptive grading technique in conjunction with the VP9/VP10 encoder is studied. Both the objective metrics (measured using BD rate) and informal subjective visual quality assessments are recorded. It is asserted that useful improvements are possible in each of these categories. In particular, substantial value is offered in the coding of HDR content, and especially in creating a coding scheme offering backwards compatibility with SDR.
