DIGITAL RIGHTS DOMAIN MANAGEMENT FOR SECURE CONTENT DISTRIBUTION IN A LOCAL NETWORK

摘要

Systems and methods for secure content distribution, including a content server, a rights management server, a residential gateway communicating with the content server and the rights management server via a network, and a playback device communicating with the residential gateway via a local network. The residential gateway receives protected content from the content server. The playback device requests access to the protected content from the residential gateway. The residential gateway requests access to the protected content from the rights management server by including information uniquely identifying the playback device. The rights management server provides access information to the residential gateway when the access information satisfies predetermined criterion for playback devices associated with the residential gateway. The residential gateway decrypts the protected content using the access information and encrypts the decrypted content for distribution to the playback device via a secure link formed between the residential gateway and the playback device.
