Abstract

CAS is an access control system by which only legal users can access contents. IPTV is a spotlighted system that uses CAS. H.264/SVC is a coding standard that provides a scalable coding method by which users who are in various network environments and have various devices can receive the contents. In this method, the contents are coded in a layered structure to make users choose the quality of the receiving contents. Therefore, contents provider should be able to control users to access only appropriate contents according to their subscriptions. The structure of CAS being employed in many applications is not suitable to control access for H.264/SVC. In this paper, we provide an efficient access control method and a key management method for H.264/SVC contents using CAS.
