ビデオコード化におけるフレーム分割

摘要

In one example, this disclosure describes a method of decoding a frame of video data comprising a plurality of block-sized coding units including one or more largest coding units (LCUs) that include a hierarchically arranged plurality of relatively smaller coding units. In this example, the method includes determining a granularity at which the hierarchically arranged plurality of smaller coding units has been split when forming independently decodable portions of the frame. The method also includes identifying an LCU that has been split into a first section and a second section using the determined granularity. The method also includes decoding an independently decodable portion of the frame that includes the first section of the LCU without the second section of the LCU.
