Abstract
The present invention is directed to a method for encoding video data in an embedded fashion in order to achieve fine granular scalable video. The method includes the video data being transformed into a plurality of DCT coefficients. Further, the DCT coefficients are arranged into sub-groups and the DCT coefficients are scanned according to the sub-groups. The DCT coefficients being scanned by the sub-groups enables a higher level of scalability to be achieved.
