Upgrade your PHABRIX Sx portable instrument and Rx rasterizer with AV Delay Analysis
AV Delay
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. Understanding the AV delay through broadcast workflows is a priority.
AV Delay for the handheld Sx Series
AV Delay for the Rx Rasterizer Series
PHABRIX’s AV Delay option for the Rx rasterizer, measures the audio-video delay through a broadcast workflow. The key features of the AV Delay option include:
When analyzing an AV delay video test pattern and audio pulse, the differential delay between the video and all 8 audio channel pairs will be measured and displayed – with the display updated in real-time.
The differential delay between the video and the selected audio is measured in 0.1ms steps (to an accuracy of 1ms) with an operating range of +/-400ms. The generator tool can be used to offset the source audio by up to 40 frames which can be used to extend the measurement operating range to over +/- 1 second.
Available on the PHABRIX SxA, SxD, SxE, Sx TAG, Rx 500, Rx 1000 and Rx 2000 instruments |
