VIDEO ENCODING METHOD AND APPARATUS AND VIDEO DECODING METHOD AND APPARATUS USING UNIFIED SYNTAX FOR PARALLEL PROCESSING

摘要

Disclosed are a video encoding method and apparatus and a video decoding method and apparatus using a unified syntax for parallel processing. The video decoding method of the present invention acquires a first data unit parallel processing flag from a first data unit header that contains encoding information of a first data unit, the flag indicating whether data that can be processed in parallel is contained in the first data unit, determines whether data that can be processed in parallel is contained in the first data unit based on the first data unit parallel processing flag, and acquires a second data unit parallel processing flag from a second data unit header that contains encoding information of a least significant second data unit in cases where data that can be processed in parallel is contained in the first data unit, the flag indicating whether data that can be processed in parallel is contained in the second data unit.
