The AV delay generation and analysis option offers a comprehensive solution for differential audio-to-video delay measurement over a transmission chain.
The tool not only provides a real-time update of the differential delay between the video content and the selected pair of audio channels, but can also be used to measure the propagation, or line delay of the video and audio content.
The generator allows to understand the AV delay through the transmission workflows although the SDI sources contain video and audio data, this does not mean that the video and audio are automatically synchronized. Also referred to as Lip-Sync error or AV delay, these variations can create a noticeable problem for the viewer. Any active processing equipment can introduce an error in AV synchronization, but compensation can only be possible at the system level.
