DIGITAL RIGHTS MANAGEMENT FOR LOCAL RECORDING AND HOME NETWORK DISTRIBUTION

摘要

The systems disclosed here provide a complete standards-based end-to-end scalable system for storage, delivery and in-home distribution of digital content over IP networks using standard protocols such as Real-time Transport Protocol ("RTP") or IP-encapsulated MPEG-2 Transport Stream, or traditional MPEG-2 networks. Mechanisms are provided for receiving (65) content from one security domain, re-encrypting (73, 76) that content uniquely for a receiving device (50), persistently storing (77) that content (86), and playing back that content (86) at a later time to and within another security domain. The systems also provide the ability to stream the persistently-stored content from the initial receiving device to another device (300) that has been authenticated as part of a, e.g., home network. This allows a media server, e.g., a dual-tuner set-top box ("STB") with hard drive (170) , to deliver recorded content to any TV in the house by streaming to media clients such as STBs.
