Abstract
A high dynamic range (HDR) signal processing device may receive a video signal and an operating mode indication. The operating mode indication may indicate a format of the video signal, for example, an HDR format or a non-DR format. Whether to perform adaptive reshaping on the video signal may be determined based on the operating mode indication. For example, it may be determined to perform the adaptive reshaping if the operating mode indicates that the video signal is in an HDR format. It may be determined to bypass the adaptive reshaping if the operating mode indicates that the video signal is in the non-HDR format. Multiple types of HDR reconstruction metadata may be received via a network abstraction layer (NAL) unit.
