Paper Abstract

This paper describes a study to investigate possible ways to improve the AV1 codec, in several directions, most particularly in the context of 10-bit HDR video content, and 8/10 bit image content. Applications to SDR video, and 360 content are discussed elsewhere. For HDR content, a data adaptive grading technique in conjunction with the AV1 codec is studied. For image content, lapped biorthogonal transforms for (near) lossless compression is studied. For scalability-type applications, we introduce advanced resampling filters which outperform current ones. 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, very competitive with HEVC HDR10, in a coding framework offering backwards compatibility with SDR. We also provide a rudimentary comparison of AV1 to the standard HEVC as well as the developing JVET codecs.
