Abstract

See full text

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.
