ABSTRACT:
A metadata extraction unit has a feature point selection and motion estimation unit62for extracting at least one feature point representing characteristics of the video/audio signals in a compressed domain of the video/audio signals. Thus, reduction of time or cost for processing can be realized and it makes it possible to process effectively.
