A METHOD AND DEVICE FOR INTRA-PREDICTIVE ENCODING/DECODING A CODING UNIT COMPRISING PICTURE DATA, SAID INTRA-PREDICTIVE ENCODING DEPENDING ON A PREDICTION TREE AND A TRANSFORM TREE

摘要

The present principles relates to a method for intra-predictive encoding a coding unit comprising picture data, said intra-predictive encoding depending on a prediction tree and a transform tree, characterized in that the method further comprises: —obtaining said prediction tree by spatially partitioning the coding unit according to a non-square partition type; —determining said transform tree from said coding unit in order that each of its leaves is embedded into a unique unit of said obtained prediction tree; and —signaling in a signal the size of the leaves of said transform tree and said a non-square partition type.
