Abstract:
Embodiments of the present invention comprise methods and systems for high dynamic range (HDR) video coding and decoding that is backwards-compatible with one or more standard dynamic range (SDR) encoding and decoding techniques, through the transmission of HDR residual data used to reconstruct an encoded HDR sequence from an inverse-tone-mapped SDR sequence.
