1. A method for scanning discrete cosine transform (DCT) coefficients, the method comprising the steps of:
- dividing the DCT coefficients into bit-planes;
arranging the DCT coefficients of each of the bit-planes into sub-groups; and
scanning the DCT coefficients of each of the bit-planes according to the sub groups.

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.
