Signaling parameter value information in parameter sets to reduce the amount of data contained in coded video bitstreams

摘要

A method (400) implemented by a decoder (260, 600, 701) for decoding a bit stream having a picture parameter set (PPS) and a first set of slices.The method includes obtaining a picture parameter set (S402).The method also includes decoding (S404) the syntax element included in the picture parameter set to obtain the indicator value.The decoder determines if the picture header included in the bit stream has a parameter value corresponding to a particular parameter if the indicator value is set to a first value, and in other cases each slice contained in the first set of slices is A set of parameters corresponding to a particular parameter is set to determine the decoder.If the picture header comprises a parameter value corresponding to a particular parameter, this parameter value is used to decrypt slice data of each slice contained in the first set of slices.Diagram
