摘要:
One or more circuits for use in a transceiver that is collocated with a satellite dish, may receive a satellite signal carrying media content, and remove content protection from the received media content. After removing the first content protection, the one or more circuits may apply second content protection to the media content. The content protection applied by the one or more circuits may adhere to a different protocol, utilize different keys, and/or otherwise be distinguishable from the content protection that was removed. After applying the content protection, the one or more circuits may transmit the media content onto one or more links between the satellite dish and one or more client devices. The removal of the content protection may comprise descrambling and/or decrypting the media content. The application of the content protection may comprise scrambling and/or encrypting the media content.
