Methods and apparatuses for secondary conditional access server
Abstract:
Conditional access to media content of primary security systems on a secondary networked environment. In one embodiment, a conditional access server is used to provide services to secondary CA clients (e.g., a bridge, a renderer, a storage, or their different combinations) through network connections. Containing data representing the subscriber, a conditional access server recovers entitlement data and/or decryption keys of a primary security system for the conditional access protected content, such as service keys and control words, and/or enforces conditional access to the content by secondary CA clients according to the authorization of the primary security system for the secondary CA clients. In one embodiment, a conditional access system provides delayed authorization for use so that the content can be recorded for later use when authorized and broadcasts rights for use on multiple secondary CA clients.
