Method and device for intra-prediction coding / decoding a coding unit comprising picture data, wherein the intra-prediction coding is dependent on a prediction tree and a transformation tree

摘要

The principle is a method for intra-prediction encoding a coding unit comprising picture data, wherein the intra-prediction coding is dependent on a prediction tree and a transformation tree, in a method according to a non-square partition type Obtaining the prediction tree by spatially partitioning the coding unit, and-converting the coding unit from the coding unit such that each leaf of the conversion tree is embedded in a unique unit of the obtained prediction tree A method, characterized in that it further comprises: determining a tree; and signaling the leaf size of the conversion tree and the non-square partition type.
