VIDEO ENCODING METHOD AND APPARATUS THEREOF, AND A VIDEO DECODING METHOD AND APPARATUS THEREOF

摘要

Disclosed is an inter layer video decoding method including reconstructing a first layer based on encoding information of the first layer obtained from a bitstream; splitting a largest coding unit of a second layer image into one or more coding units based on split information of the second layer image obtained from the bitstream; splitting the coding units into one or more prediction units for prediction encoding; and determining whether to use a predetermined coding tool based on at least one of a prediction mode of a current prediction unit, size information, and color depth information and decoding the current prediction unit using the predetermined coding tool according to whether to use the predetermined coding tool.
