Abstract
In a method to reconstruct a high dynamic range video signal, a decoder receives a base layer standard dynamic range video signal, an enhancement layer video signal, a metadata bitstream for a reference processing unit and a CRC code related to the metadata. A decoder reconstructs a high-dynamic range video output signal based on the base layer video signal, the enhancement layer video signal, and the data syntax and metadata specified by the metadata bitstream.
