摘要： The present invention is directed towards providing a partial dual-encrypted stream in a conditional access overlay system. The headend equipment includes an aligner, identifier, and remapper (AIR) device (615) that receives a clear stream and one or two encrypted streams, where the two encrypted streams have been encrypted by two different encryption schemes. The AIR device (615) identifies critical packets associated with the clear stream and subsequently allows two encrypted streams to pass and drops the critical packets of the clear stream. A multiplexer (640) then combines a percentage of the non-critical packets of the clear stream and the critical packets of the two encrypted streams to provide the partial dual-encrypted stream.

摘要： A cable television system provides conditional access to services. The cable television system includes a headend from which service “instances,” or programs, are broadcast and a plurality of set top units for receiving the instances and selectively decrypting the instances for display to system subscribers. The service instances are partially-encrypted using public and/or private keys provided by service providers or central authorization agents. Keys used by the set tops for selective decryption may also be public or private in nature, and such keys may be reassigned at different times to provide a cable television system in which piracy concerns are minimized.
摘要翻译：有线电视系统提供条件访问服务。有线电视系统包括广播服务“实例”或节目的前台，以及用于接收实例的多个机顶单元，并选择性地解密实例以供系统用户显示。服务实例使用由服务提供商或中央授权代理提供的公共和/或私钥进行部分加密。用于选择性解密的设置顶部使用的密钥也可以是公共的或私有的，并且可以在不同的时间重新分配这些密钥，以提供最小化盗版问题的有线电视系统。

摘要： A server in a subscriber television network receives service instances from a headend of the subscriber television network. The server is adapted to encrypt according to an encryption scheme and re-transmit service instances to a client-receiver. The server reformats the service instance from a first format into a second format the client-receiver can access the service instance.

摘要： A conditional access overlay system utilizing partial encryption without requiring additional program identifiers. The conditional access overlay system generates duplicate critical packets for separate encryption that are sent using the same packet identifier. The rest of the content stream is sent in the clear. However, these duplicated packets are sent without incrementing a continuity counter relative to one another. The overlay packets with non-incremented continuity counter are sent as the second packet immediately following the original critical packet. At the receivers, the incumbent set-top will use the first of the two encrypted packets while the overlay set-top is programmed to use the second of the two encrypted packets. Therefore, methods for verifying alignment of associated packets may be used to distinguish between multiple encryption methods in conditional access overlay systems.
摘要翻译：一种利用部分加密而不需要附加程序标识符的条件访问覆盖系统。条件访问覆盖系统生成用于使用相同数据包标识符发送的单独加密的重要关键数据包。内容流的其余部分以清晰的方式发送。然而，这些重复的分组被发送而不增加相对于彼此的连续性计数器。具有非递增连续性计数器的覆盖数据包作为紧随原始关键数据包的第二个数据包发送。在接收机上，现有机顶盒将使用两个加密分组中的第一个，而叠加机顶编程则使用两个加密分组中的第二个。因此，用于验证关联分组的对准的方法可以用于区分条件访问覆盖系统中的多个加密方法。

摘要： A system and method for retrieval and transfer of encrypted content from a first set-top box utilizing a second set-top box. When content is recorded to the storage device of the first set-top box, the content is encrypted with a content instance key. This content instance key is encrypted with the public key of the first set-top box and a duplicate of the content instance key is encrypted by the public key of the second set-top box. The encrypted content on the storage device may be retrieved by decrypting the duplicate content instance key with the private key that corresponds with the public key of the second set-top box that encrypted the duplicate of the content instance key.

摘要： A system and method for encrypting and recording content to removable storage media for use by multiple set-tops. When content is recorded to the storage media, the content is encrypted with a content instance key. This content instance key is encrypted with the public key of one set-top box and a duplicate of the content instance key is encrypted with the public key of another set-top box. Either set-top box may decrypt the content instance key with the private key that corresponds with its public key so that the encrypted content from the removable storage media may be made available in the clear.

摘要： A method for determining whether the terminal is authorized to receive the selected service is practiced in a terminal of a conditional access system in which a user selects a service, the selected service being associated with a frequency, the terminal having a tuner and a secure element with at least one authorized entitlement unit number stored therein. The method includes receiving at least one encrypted entitlement control message corresponding to the service, and decrypting each of the at least one encrypted entitlement control message in the secure element, each decrypted entitlement control message revealing at least one first entitlement number associated with the selected service. The method further includes determining that the terminal is authorized to receive the selected service when any first entitlement number of any decrypted entitlement control message represents any number of the at least one authorized entitlement unit number. Alternatively, the method includes receiving at least one entitlement control message corresponding to the service, and authenticating each of the at least one entitlement control message in the secure element, each authenticated entitlement control message revealing at least one first entitlement number associated with the selected service. The method further including determining that the terminal is authorized to receive the selected service when any first entitlement number of any authenticated entitlement control message represents any number of the at least one authorized entitlement unit number.

摘要： Examples of a system, method, and apparatus for encrypting and recording content are presented. When content is recorded to storage media, the content is encrypted with a content instance key. This content instance key is encrypted with the public key of a first set-top box and a duplicate of the content instance key is encrypted with the public key of other than said first set-top box. A private key corresponding with the public key of the first set-top box may be used to decrypt the content instance key, or a private key corresponding to the public key of other than the first set-top box may be used to decrypt the duplicate of the content instance key so that the encrypted content from the removable storage media may be made available in the clear.
