METHOD AND APPARATUS FOR GENERATING SECURITY LABEL FOR SCALABLE CONTENTS DISTRIBUTION

摘要

PURPOSE: A method for generating security labels for distributing scalable contents and a device thereof are provided to apply a differentiated security policy which is evaluated by performance indexes to a service in consideration of requirements and service conditions which are different for each scalable unit. CONSTITUTION: A scalable content transmitting unit(1100) generates a security label and an encoded scalable unit. A scalable content receiving unit(1200) receives the encoded scalable unit and the security label. The scalable content receiving unit decodes, reproduces, modifies, stores, or redistributes the encoded scalable unit according to the security label. A scalable content storage(1000) searches scalable content and metadata corresponding to a request of the scalable content transmitting unit.
