System and Method of Managing Protected Video Content

摘要

A method includes inspecting a packet stream sent from a set-top box device via a network. The packet stream includes video content that is divided into a plurality of subsections. The method includes generating a plurality of signatures by applying a wavelet transform to each of the plurality of subsections, and determining a match between the video content and protected video content based at least in part on a comparison of the plurality of signatures to one or more stored signatures generated based on the protected video content.
