METHOD AND APPARATUS FOR SELECTIVELY ENCODING/DECODING SYNTAX ELEMENTS, AND APPARATUS AND METHOD FOR IMAGE ENCODING/DECODING USING SAME |
摘要 |
An apparatus and a method for motion vector encoding/decoding, and to an apparatus and a method for image encoding/decoding using same are provided. The apparatus includes a selector of optimal predicted motion vector PMV from candidate motion vector set of current block; a determiner of motion vector prediction mode of current block with selected motion vector prediction mode from multiple motion vector prediction modes by decision criterion prearranged with motion vector decoding apparatus; and an encoder for determining, by determined motion vector prediction mode, optimal PMV or default predicted motion vector into PMV for current motion vector, encoding differential vector between the current block and PMV, and selectively encoding/outputting determined motion vector prediction mode as encoded motion vector prediction mode by the determined motion vector prediction mode. Bit quantity in encoding a motion vector is reduced improving encoding efficiency and preventing decoder crash even at encoding error, improving decoder.
