METHOD AND APPARATUS OF HIGH-LEVEL SYNTAX FOR SMOOTHING INTRA-PREDICTION TECHNIQUES

摘要

A method of high-level signaling for a video coding method with intra-prediction of a block, the method comprising: signaling a set of low-level indicators for the predicted block, wherein each of the indicators of the set enables or disables an intra prediction smoothing mechanism for the predicted block; signaling a first set of high-level indicators on a slice-level or a higher level, wherein each of the high-level indicators of the first set determines signaling for an intra prediction smoothing mechanism which is enabled or disabled by an indicator of the set of low- level indicators; and signaling a second set of high-level indicators, wherein each of the high- level indicators of the second set determines the presence of at least one of the corresponding high-level indicators of the first set, and wherein the values of corresponding high-level indicators of the first set are inferred to be zero when the value signaled by high-level indicator of the second set is zero.
