ABSTRACT:
A system for multi-stream security processing and distributing digital media streams includes a headend, a network, and at least one receiver. The headend is generally configured to generate encrypted digital media streams. The network may be coupled to the headend and configured to receive the encrypted digital media streams. The at least one receiver may be coupled to the network and configured to receive the encrypted digital media streams and present a decrypted version of the encrypted digital media streams. At least one of the headend and the at least one receiver include a security processor that may be configured to provide at least one of simultaneous multiple encryption and simultaneous multiple decryption processing of the digital media streams.
