Understanding the AV delay through your broadcast workflows is a priority

Although SDI feeds hold both video and audio data, this does not mean that the video and audio are automatically in-sync. Variously referred to as a lip sync error or AV delay, offsets can create a noticeable issue for the viewer. Any active processing equipment can introduce an error in AV timing, but compensation may only be possible at the system level.

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 chain. The tool not only provides a real-time update of the differential delay between the video content and the selected audio channel pair but can also be used to measure the propagation (latency), or pipeline delay, of video and audio content.
