Delay Test

Overview: This article describes three methods to test the latency of the device correctly.

Method 1 ：

• Delay1:  the video source from the camera to the monitor directly.
• Delay2:  the video source from the camera to TX, then from TX to RX, finally to the monitor.
• The equipment delay is the difference between Delay1 and Delay2.

Method 2 : 

Method 3 : 

     Operation：

• Clap your hands in scene 1 and scene 2, using the OBS to record the video separately and analyze video and audio latency by software(Pr).
• 
  

• As the picture show, the latency between audio and video is T2 minus T1.

• Test the latency between audio and video of Scene 1 and Scene 2 separately and mark it to T and t, the latency of the wireless transmission system is T minus t.
