Abstract
A video encoding method, a video encoding apparatus, a video decoding method, and a video decoding apparatus are provided. The video encoding method includes reconstructing a first layer image based on encoding information of the first layer image that is obtained from a bitstream, splitting a largest coding unit of a second layer image into coding units based on split information of the second layer image that is obtained from the bitstream, splitting the coding units into prediction units for prediction encoding, determining whether to use a coding tool for decoding a current prediction unit based on at least one among a prediction mode of the current prediction unit among the prediction units, size information of the current prediction unit, and color depth information of the current prediction unit, and decoding the current prediction unit, using the coding tool, in response to the determining to use the coding tool.
