摘要:
A method of managing protected video content is presented that includes inspecting a packet stream received from a subscriber broadband interface, where the packet stream includes video content. The method also includes generating a signature based on the video content and comparing the generated signature with a stored signature corresponding to protected video content. In a particular embodiment, the method can include storing data indicating that the protected video content has been re-distributed from the subscriber broadband interface when the generated signature matches the stored signature.
