7BM77: Lip-Sync Measurement (AV Delay) for TV Displays

Abstract
Determining the delay of the video signal in relation to the audio signal aids evaluation of the quality of screens with an audio output. In some cases, such delays can reach as much as 100ms, which can cause significant irritation. This delay occurs because videosignal processing requires more computing power than audio-signal processing. The measurement solution described in this application note analyzes delays of up to +-400ms at a resolution in the order of µs.
