In scal-able video coding, hierarchical MCTF is extensively adopted to exploit the temporal correlation across video frames. In this hierarchical MCTF structure, the strength of temporal correlation varies with the level of temporal trans-
WebH.265/HEVC supports two types of frame coding structures including random access (RA) and low delay (LD) , where different frames form a set of hierarchical structures within a group-of-picture (GOP) and the frames at a higher coding layer can be predicted from one or more frames at lower coding layers. Webhierarchical encoding A method of image coding that represents an image using a sequence of frames of information. The first frame is followed by frames that code the differences between the source data and the reconstructed data from the previous frames for that image. Source for information on hierarchical encoding: A Dictionary of …
