摘要
Video processing method, apparatus and computer program product are disclosed. The video processing method comprises: determining a quantization parameter to be used in a dependent scalar quantization of a current video block in case that the dependent scalar quantization is enabled for the current video block, wherein a set of admissible reconstruction value for a transform coefficient corresponding to the dependent scalar quantization depends on at least one transform coefficient level that precedes a current transform coefficient level; and performing the dependent scalar quantization on the current video block in accordance with the determined quantization parameter, wherein the determined quantization parameter is also applied to a video process different from the dependent scalar quantization using a quantization parameter as an input parameter of the current video block.
