Phabrix PHRXO-AVD is an AV delay analyzer generation and analysis software license for the RX series. Although SDI feeds hold both video and audio data, it does not mean that the video and audio are correctly in-sync. Referred to as a Lip Sync Error, or AV Delay, the results can sometimes create a noticeable issue for the viewer, especially in broadcast workflows where feeds are encoded.
There is a potential that any active processing equipment can introduce AV Delay, but compensation for this may only be possible as a system solution not on a unit by unit basis. Therefore, understanding the likely accumulated AV Delay is a priority.
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 system.
The tool provides a real-time update of the differential delay between the video and the selected audio channel pair
Measure the propagation or pipeline delay of either video or audio
Can be used with all Rx supported video formats and frame rates on SDI and AES interfaces
