Method for encoding and decoding image information to determine reference index in skip mode or merge mode and device using same

摘要

A decoding method includes entropy-decoding received information, performing inter prediction on a current block based on the entropy-decoded information, and restoring images by using the prediction results. A skip mode or merge mode is applied to the current block and movement information of the current block and may be determined based on the movement information of a neighboring block of the current block.
