  • Patent number: 11197029
    Abstract: A method (400) performed by a decoder (260, 600, 701) for decoding a bitstream comprising a picture parameter set, PPS, and a first set of slices. The method includes obtaining (s402) the picture parameter set. The method also includes decoding (s404) a syntax element included in the picture parameter set to obtain an indicator value. The decoder is configured such that if the indicator value is set to a first value then the decoder determines that a picture header included in the bitstream comprises a parameter value corresponding to a particular parameter, otherwise the decoder determines that each slice included in the first set of slices comprises a parameter value corresponding to the particular parameter. If the picture header comprises the parameter value corresponding to the particular parameter, then this parameter value is used to decode slice data of each slice included in the first set of slices.
