Systems and methods of measuring a temporal offset between audio content and video content that employ audio fingerprints from an audio signal in the audio content, and video fingerprints from video frames in the video content. The systems obtain reference audio and video fingerprints prior to transmission of video over a media channel, and obtain target audio and video fingerprints subsequent to transmission of the video over the media channel. Each fingerprint has an associated time stamp. Using the reference and target audio fingerprints and their associated time stamps, the systems determine an audio time stamp offset. Using the reference and target video fingerprints and their associated time stamps, the systems determine a video time stamp offset. Using the audio and video time stamp offsets, the systems determine a temporal offset between the video content and the audio content introduced by the media channel.
