Although SDI feeds hold both video and audio data, it does not mean that the video and audio are correctly in-sync. Referred to as a Lip Sync Error, or AV Delay, the results can sometimes create a noticeable issue for the viewer, especially in broadcast workflows where feeds are encoded.
There is a potential that any active processing equipment can introduce AV Delay, but compensation for this may only be possible as a system solution not on a unit by unit basis. Therefore, understanding the likely accumulated AV Delay is a priority.
PHABRIX’s AV Delay Generation and Analysis option offers an end-to-end solution for the measurement of Audio to Video differential delay through a broadcast system. AV Delay is available on the handheld SxA, SxD and SxE instruments.
