Patent attributes
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.
