Decoding video data using a two level multitype tree framework

摘要

An exemplary device for decoding video data includes a video decoder, the video decoder including one or more at an area tree level of an area tree of a tree data structure for coding tree blocks (CTBs) of the video data. The syntax element is decoded, and the region tree has one or more region tree nodes including region tree leaf nodes and non-leaf nodes, and each of the region tree non-leaf nodes has at least four child region tree nodes , Decoding one or more syntax elements at the prediction tree level for each of the region tree leaf nodes of one or more prediction trees of the tree data structure of the CTB, the prediction tree being each one or more predictions It has tree leaf nodes and non-leaf nodes, and each of the prediction tree non-leaf nodes has at least 2 It has a child prediction tree node, each of the predicted leaf nodes define each of the coding units (CU), configured to decode the video data for each CU.
