Claim 10:
11. A non-transitory storage medium which includes an encoded bitstream, the bitstream being generated by dividing a current picture of a video signal or an image signal into a plurality blocks, and comprising a plurality of syntax elements, wherein the plurality of syntax elements comprises a first syntax element in a sequence parameter set (SPS), wherein a value of the first syntax element is used to specify whether a decoded picture buffer (DPB) parameters syntax structure is present in the SPS; in case that the value of the first syntax element specifies that the DPB parameters syntax structure is present in the SPS and a maximum number of temporal sublayers in the bitstream is greater than one, the bitstream further comprises a second syntax element in the SPS, wherein a value of the second syntax element is used to specify presence of a DPB syntax element in the DPB parameters syntax structure, wherein the DPB syntax element is applied to a temporal sublayer.
