METHOD AND APPARATUS FOR VIDEO ENCODING TRANSFORMATION INDEX REGARDING STRUCTURE OF DATA UNIT FOR TRANSFORMATION, METHOD AND APPARATUS FOR VIDEO DECODING BASED ON THE TRANSFORMATION INDEX

摘要

Disclosed is a method for video decoding, which determines a transformation unit for performing transformation of a current encoding unit among encoding units which is a data unit for encoding a current picture, and encoding a current encoding unit by including transformation based on the transformation unit to use a transformation index outputting encoded data on the current encoding unit, transformation index information for an encoding mode, and transformation index information for a structure of a transformation unit.
