Abstract
A security label generation apparatus for scalable content distribution, includes a scalable content transmitter for receiving service level requirements of a user and network bandwidth information over a network and generating security labels and encrypted scalable units. Further, the security label generation apparatus includes a scalable content receiver for receiving the encrypted scalable units and the security labels from the scalable content transmitter and for decrypting, decoding, playing, modifying, storing or redistributing the encrypted scalable units based on the security labels. Furthermore, the security label generation apparatus includes scalable content storage for searching for scalable content and metadata corresponding to a request of the scalable content transmitter.
