This paper describes high-quality compression of high dynamic range (HDR) video using existing tools such as the HEVC Main 10 profile, the SMPTE ST 2084 (PQ) transfer function, and the BT.2020 non-constant luminance Y'CbCr color representation. First, we present novel mathematical bounds that reduce complexity of luminance-preserving subsampling (luma adjustment). A nested look-up table allows for...
We consider the problem of equalizing the quantization noise between two video encoders operating with video stored using different transfer function. Here, a transfer function is the mapping between linear light and the quantized code words and includes, for example, the well-known “gamma curve” used for most video applications. Our motivation for studying this problem is that the solution enables...
