Phabrix
Phabrix Sx analyzers and Rx rasterizers are updated to include the AV Delay Analysis feature for SDI sources, offering an end-to-end solution for measuring differential audio-to-video delay over a transmission chain.
These sources, although they contain video and audio data, do not mean that they are automatically synchronized, a phenomenon also known as Lip-Sync error. Any active processing equipment can introduce an error in AV synchronization, but compensation can only be possible at the system level.
The tool not only offers 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.
This functionality can perform real-time AV delay measurement up to +/- 400 ms in 0.1 ms steps (accuracy = 1 ms), and on the Rx rasterizer (2K/3G/HD/SD) measures audio and video delay through a streaming workflow.
A positive (+) measurement indicates that the audio pulse is lagging behind the video.
A negative (-) measurement indicates that the audio pulse is ahead of the video.
When the video and audio are fully synchronized, zero delay will be measured.
This feature is available on Phabrix SxA, SxD, SxE, Sx TAG, Rx 500, Rx 1000 and Rx 2000 computers.
