摘要： A system and method for registering a client device with a server device includes the server device having a display. The display displays a first identifier in response to entering a registration mode. A client device is in communication with the server device. The client device detects that the server device is in registration mode and communicates a second identifier to the client device. The server device compares the first identifier and the second identifier and, after comparing, registers the client device at the server device.

摘要： A method and apparatus for distributing video content from a direct broadcast satellite system between a host receiver and a client receiver. A family pairing key is transmitted from the direct broadcast satellite system to both the host and client receivers. The family pairing key received by the host and client receivers is decrypted using receiver keys uniquely associated with the host and client receivers, respectively. Decrypted program materials are then encrypted at the host receiver using a copy protection key generated by the host receiver using content information decrypted by the family pairing key. The encrypted program materials are transferred from the host receiver to the client receiver. The encrypted program materials are decrypted at the client receiver using the copy protection key. Like the host receiver, the copy protection key is generated by the client receiver using content information decrypted by the family pairing key.

摘要： Program materials received from a direct broadcast satellite system are distributed between a host receiver and a client receiver for remote decryption. Using either a same pairing key or different host and client pairing keys, an encrypted media encryption key is received at both the host and client receivers, and the encrypted media encryption key is decrypted at both the host and client receivers using the pairing key. Encrypted program materials are received from the broadcast system at the host receiver, and the encrypted program materials are decrypted at the host receiver using the media encryption key. The encrypted program materials are also transferred from the host receiver to the client receiver, where the encrypted program materials are decrypted at the client receiver using the media encryption key.

摘要： A communication system 10 includes a head end 12 that generates a device list with channel or content authorizations. The head end communicates the list to a system gateway 26. The gateway 26 receives the list. A plurality of user devices 28 is coupled to the gateway 26. A first device of the plurality of user devices generates a channel or content request at the system gateway. The gateway 26 compares the channel or content authorizations from the list to the channel request from the first user device and communicates to the first user device a channel or content corresponding to the channel request in response to comparing. Thus, authorized users are able to receive the channel or content in response to the list. The list may be generated at a subscriber information module 52 and communicated with the content or channel through a satellite 18 or through a communication network 50.

摘要： Methods and an apparatus for distributing digital content via a host receiver (e.g., direct-to-home satellite host receiver) are disclosed. The disclosed techniques include transmission of a host identifier and a client identifier from a host receiver and a client device to a satellite transmission station. The identifiers are used by the transmission station to lookup unique encryption keys associated with the host receiver and client device. The transmission station then transmits one or more encrypted keys to the host and/or client. In addition, the transmission station transmits encrypted content to the host. In turn, the host decrypts the content using one encryption key, re-encrypts the content using another encryption key, and passes the content along to the client device. By using the smart card, tuner, and/or storage device of the host receiver, the client device need not include a smart card, tuner, and/or storage device.
摘要翻译：公开了用于经由主机接收机（例如，直接到家庭卫星主机接收机）分发数字内容的方法和装置。所公开的技术包括将主机标识符和客户机标识符从主机接收机和客户端设备传输到卫星传输站。标识符被发送站使用以查找与主机接收器和客户端设备相关联的唯一加密密钥。然后，发送站将一个或多个加密的密钥发送到主机和/或客户端。此外，发送站向主机发送加密的内容。反过来，主机使用一个加密密钥解密内容，使用另一个加密密钥重新加密内容，并将内容传递到客户端设备。通过使用主机接收机的智能卡，调谐器和/或存储设备，客户端设备不需要包括智能卡，调谐器和/或存储设备。

摘要： In a broadcast system for transmitting a communication signal to a plurality of receiver units, each receiver unit having associated therewith respective authorization information identifying subsets of the communication signal the receiver unit is authorized to process, a method for controlling access to the communication signal includes the step of receiving a conditional instruction. The conditional instruction specifies a modification of the authorization information conditioned upon whether the receiver unit belongs to a receiver unit category. The method further includes the step of executing the conditional instruction to modify the authorization information conditioned upon whether the receiver unit belongs to the receiver unit category.
