METHOD AND DEVICE FOR ENCODING/DECODING IMAGE USING ADAPTIVE ENCODING/DECODING MODE INDEXING METHOD

摘要

A video encoding/decoding apparatus and method using adaptive encoding/decoding mode indexing are provided. A video encoding apparatus includes: a probability generation unit for calculating a probability of each encoding mode of blocks completely encoded before a current block; a bit assignment unit for assigning and indexing a bin string according to the probability of each encoding mode, which is calculated by the probability generation unit; and a video encoding unit for encoding an encoding mode of the current block, based on the bin string assigned by the bit assignment unit, when the current block is encoded.
