Qligent will introduce A/V Sync Detection, a software solution designed to detect and flag A/V Sync (or lip sync) problems.
Qligent will introduce A/V Sync Detectiona software solution designed to detect and flag A/V Sync (or lip sync) problems at NAB. Qligent first unveiled A/V Sync Detection at IBC in September.
A/V Sync Detectionwhich Qligent will demo at booth N5914 is a standard feature within Match, a software module responsible for monitoring and detecting a range of programmatic errors out to the last mile of the multiplatform distribution domain. A/V Sync and Match are part of the Qligent Vision cloud-based monitoring solution, a broad toolset for monitoring and analysing signal quality in todays broadcast distribution environment.
Armed with this frame-accurate analysis, broadcasters can determine the root cause of the problem and take steps to correct it, said Ted Korte, Qligents COO, Without it, broadcasters would be hard pressed to know where programmatic and lip sync errors are occurring in any and all downstream channels that carry their branded content to viewers.
More importantly, Korte added, A/V Sync Detection can flag variations in video and audio synchronisation down to one millisecond of accuracy. This level of accuracy is especially critical for Web and OTT streaming where latency delays can easily occur along the stream path.
By adding A/V Sync Detection to the Vision platform, Korte added, Were empowering broadcasters by giving them the means of determining where the A/V sync fell apart, even if it occurred on a third-party distribution platform, so they can alert the responsible parties and restore an optimal quality of experience (QoE) for their viewers.
