Abstract:
An architecture of multilayered DRM protection structure for multimedia service and the method of forming the same are provided. The architecture comprises a multilayered DRM encryption structure and a DRM decryption structure. The inputted multimedia service is decomposed and encrypted into an encrypted multimedia service stream through a multimedia service decomposer and a multimedia DRM organizer. The encrypted stream is decrypted by a DRM composer from top layer to bottom layer. A full or partial multimedia service is then presented. For a multimedia service application, this enhances the DRM protection by increasing the complexity of multimedia encryption for a multimedia service application. It also provides the variety for the multimedia service application via different compositions of multimedia objects. The DRM protection structure is embedded into each layer of multimedia services and objects and can be set up different levels of DRM protection.
