METHOD AND APPARATUS FOR ENCODING IMAGES AND METHOD AND APPARATUS FOR DECODING IMAGES

摘要

An apparatus for decoding an image includes an encoding information extractor which extracts split information indicating whether to split a coding unit of an upper depth into coding units of deeper depths and skip information indicating whether a prediction mode of a current coding unit is a skip mode, from image data and a decoding unit which determines a split structure of a maximum coding unit, according to the split information so that the maximum coding unit is hierarchically split as a depth increases and determines whether the prediction mode of the current coding unit is the skip mode according to the skip information.

1. An apparatus for decoding an image, the apparatus comprising:
an encoding information extractor which extracts split information indicating whether to split a coding unit of an upper depth into coding units of deeper depths and skip information indicating whether a prediction mode of a current coding unit is a skip mode, from a bitstream; and a decoding unit which determines a split structure of a maximum coding unit, according to the split information so that the maximum coding unit is hierarchically split as a depth increases and determines whether the prediction mode of the current coding unit is the skip mode according to the skip information.
