Abstract
Encoding and decoding systems disclosed enhance the AV1/VPX codecs in the context of 8-bit SDR video and 10-bit HDR video content, for applications including streaming and high quality coding for content contribution editing. For SDR content, lapped biorthogonal transforms for near lossless applications and used and optimized resampling filter pairs for adaptive resolution coding in streaming applications are used. For HDR content, a data adaptive grading technique in conjunction with the VP9/VP10 encoder may be used. The encoding/decoding system provides substantial value in the coding of HDR content, and provides backward compatibility with SDR.
