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:

1. Test Setup

   • Video Source: A computer running a stopwatch application with millisecond precision.

   • 画面 1 (参照): The computer monitor directly showing the stopwatch (real-time source).

   • 画面 2 (テスト): A video player connected via wired Ethernet, receiving the HDMI-to-IP video stream output from the converter.

2. Testing Method

   • Play the stopwatch on the computer (source).

   • Observe both Display 1 (direct HDMI output) and Display 2 (network video stream playback) 同時に.

   • 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.

3. 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, 生放送, 遠隔監視, 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.
