Abstract

A video decoder decodes a video from a video bitstream encoded using Versatile Video Coding (VVC). The video decoder determines a bit depth of samples of the video based on Sequence Parameter Set (SPS) syntax element sps_bitdepth_minus8 whose value is in the range of 0 to 8. The decoder further determines the size of a decoded picture buffer (DPB) based on a Video Parameter Set (VPS) syntax element vps_ols_dpb_bitdepth_minus8 whose value is in the range of 0 to 8. The decoder allocates a storage space with the determined size of the DPB, decodes the video bitstream based on the determined bit depth, and thus obtains and stores a decoded picture in the DPB. The decoder further outputs the decoded picture.
