APPRAATUS AND METHOD FOR HIGH EFFICIENCY VIDEO CODING USING FLEXIBLE SLICE STRUCTURE

摘要

An apparatus and method for video encoding using flexible slice structure are disclosed, wherein the method for video coding comprises steps of partitioning video input data into largest coding units (LCUs), configuring a slice to include a plurality of LCUs, having a first LCU and a last LCU, wherein the first LCU and the last LCU are selected from a group consisting of a fractional LCU and a whole LCU, and wherein the fractional LCU is formed by partitioning the whole LCU into leaf CU according to a quadtree, applying video coding to the slice to generate compressed video data for the slice, generating a slice layer bitstream comprising the compressed video data for the slice and generating a video bitstream comprising the slice layer bitstream. Various syntax elements are incorporated into video bitstream according to the present invention to allow conveyance of the flexible slice structure between an encoder and a decoder. An apparatus and method for video decoding using flexible slice structure are also disclosed.
