Abstract:
A method for decoding of a video bitstream implemented by a decoding device, wherein the video bitstream includes data representing one or more sequence parameter set, SPS, flags, the method comprising: for an SPS flag of the one or more SPS flags, obtaining two variables of the SPS flag, respectively, by parsing the video bitstream, wherein the value of one variable of the two variables is the minimum allowed value of the SPS flag, and wherein the value of the other variable of the two variables is the maximum allowed value of the SPS flag; obtaining the SPS flag, by parsing the video bitstream; evaluating whether the value of the SPS flag is valid based on the values of the two variables; and in case that the value of the SPS flag is valid, decoding the video bitstream according to the value of the SPS flag.
