  • Publication number: 20230100134
    Abstract: An electronic device of decoding a current video block in a video picture is provided. The electronic device determines whether a partitioning scheme of the current video block is a single tree partitioning or a dual tree partitioning. The electronic device selects, based on the partitioning scheme, one derivation from candidate derivations to compute a first predictive quantization parameter (QP) for the current video block. A first derivation comprises computing the first predictive QP based at least in part on another QP and an additional value when the partitioning scheme is the single tree partitioning. A second derivation comprises computing the first predictive QP by using a previously-derived QP when the partitioning scheme is the dual tree partitioning. The electronic device computes a second QP based at least in part on the first predictive QP and an offset value, and use the second QP to decode the current video block.
