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

The present invention provides a method for encoding a video using a conversion index, comprising: determining a conversion unit for converting a current encoding unit among encoding units, which are data units for encoding a current picture; and encoding the current encoding unit including conversion based on the conversion unit to output data of the currently encoded unit, information about the encoded mode, and conversion index information for the structure of the conversion unit.
