Abstract

In one example, a method performed by a processing system including at least one processor includes obtaining a first stream of audio and video data, wherein the first stream of audio and video data comprises a lower-resolution version of a second stream of audio and video data that is transmitted to a first user device over a content distribution network and encrypted using a high-bandwidth digital content protection protocol, performing an analysis technique on the first stream of audio and video data in order to extract audio and video artifacts which from which content of the first stream of audio and video data is inferred, deriving a signature marker from the audio and video artifacts, and sending the signature marker to the first user device.
