How to test the latency
To evaluate the transmission latency of the HDMI to IP video stream converter, the following test setup and method were used:
-
Test Setup
-
Video Source: A computer running a stopwatch application with millisecond precision.
-
Display 1 (Reference): The computer monitor directly showing the stopwatch (real-time source).
-
Display 2 (Test): A video player connected via wired Ethernet, receiving the HDMI-to-IP video stream output from the converter.
-
-
Testing Method
-
Play the stopwatch on the computer (source).
-
Observe both Display 1 (direct HDMI output) and Display 2 (network video stream playback) simultaneously.
-
Pause the video at any frame where both stopwatch displays are visible.
-
Record the time shown on Display 1 (source) and Display 2 (network playback).
-
Subtract the two values to obtain the end-to-end latency of the HDMI to IP video stream.
-
-
Result Interpretation
-
The difference in milliseconds represents the actual transmission latency.
-
Multiple measurements at different time points should be taken and averaged for higher accuracy.
-
This test method is suitable for evaluating real-time streaming performance in applications such as UAV transmission, live broadcasting, remote monitoring, and interactive video systems.

How to test the latency
The following video demonstrates a latency test for converting HDMI video to a network stream. A millisecond-level stopwatch is shown on one computer, whose HDMI output is connected to the converter board. The board encodes the video and transmits it over the network to a second computer. Using an RTSP player, the video stream—including the stopwatch—can be viewed in real time. Playback can be paused at any moment to compare the timestamps on both screens; the difference between them reflects the latency introduced by the HDMI-to-network encoder.
