摘要： An embodiment of a method for secure escrow and recovery of media device content keys includes generating, with a first processor of a media device, an escrow key for encrypting a plurality of content keys, the content keys for encrypting instances of media content. The first processor of the media device encrypts the escrow key with a public key of a key clearinghouse. The escrow key, encrypted with the public key of the key clearinghouse, is stored in a storage location outside of the first processor of the media device.

摘要： A conditional access device is provided. The conditional access device typically includes conditional access decryption, interface, timing and control logic. The conditional access decryption logic decrypts an incoming signal for use in a consumer electronics device in accordance with previously received entitlement management messages. The interface logic receives a control signal including an entitlement management message window from a headend control system through a receiver in the consumer electronics device. The timing logic asserts an awake signal responsive to the entitlement management message window becoming active. The control logic sends a request to the consumer electronic device to activate a receiver coupled to the headend control system in expectation of receiving an entitlement management message via the control signal in response to assertion of the awake signal. The control logic also communicates the entitlement management message to the conditional access decryption logic. Other systems and method are also provided.

摘要： Systems and methods are disclosed for inserting programs into broadcasted primary programs by a conditional access (CA) module that is inserted into a host device, such as a digital-ready television. The CA module utilizes primary and secondary program map tables and/or primary and secondary packet identifiers. A splicer splices the secondary packet identifiers, which is associated with a secondary program, into the primary packet identifiers, which is associated with a program, such as a broadcasted program. Additionally, the CA module may contain memory that is capable of storing the secondary program's packet identifiers and/or program map table that can be used for insertion into the primary program.
摘要翻译：公开的系统和方法用于通过被插入诸如数字就绪电视之类的主机设备中的条件访问（CA）模块将程序插入到广播的主程序中。 CA模块使用主节目映射表和辅助节目映射表和/或主要和次要分组标识符。拼接器将与次要程序相关联的辅助分组标识符分解成与诸如广播节目的程序相关联的主分组标识符。此外，CA模块可以包含能够存储可用于插入到主程序中的次级程序的分组标识符和/或程序映射表的存储器。
