High-Performance Single Layer High Dynamic Range (HDR) System for use in Consumer Electronics devices; Part 2: Enhancements for Perceptual Quantization (PQ) transfer function based High Dynamic Range (HDR) Systems (SL-HDR2) (V1.1.1)
The present document specifies the HDR-to-HDR/SDR content-based dynamic metadata and the post-decoding process enabling reconstruction from the specified metadata and an HDR signal of an SDR signal (100 cd/m2 or less) or an HDR signal with a maximum luminance ranging from 100 cd/m2 to a maximum luminance that is higher than that of the original HDR signal. This reconstruction process is typically invoked in a Consumer Electronics device such as a TV set@ a smartphone@ a tablet@ or a Set Top Box. Besides@ it provides information and recommendations on the usage of the described HDR system.
