SYSTEMS AND METHODS FOR SIGNALING PICTURE INFORMATION IN A SLICE HEADER IN VIDEO CODING

摘要

This disclosure relates to video coding and more particularly to techniques for signaling picture information in a slice header for coded video. According to an aspect of an invention, a first flag syntax element specifying whether a picture header is present in a slice header is parsed; a second flag syntax element, specifying a luma mapping is used for a current slice or a luma mapping with a chroma scalling is not used for a current slice, and a third flag syntax element, specifying whether a scaling information for the current slice is derived, are parsed based on the first flag syntax element.
