Abstract: A transform processor may process original data that includes video information by using at least one of first and second processing methods, and generates at least one of first and second transformed data. Index determination logic may determine an index satisfying a determination condition based on at least one of the first and second transformed data. Energy compaction determination logic may determine energy compaction of at least one of the first and second transformed data based on the determined index. Output selection logic may selectively output one of the first and second transformed data based on the determined energy compaction. An entropy encoder may encode data output from the output selection logic.
