• Onboard keys include:
  • Ключ1: OSD display toggle or multi-channel video switching (split-screen/full-screen mode).

    • The OSD key allows users to toggle the On-Screen Display (OSD) on or off. Pressing and holding the key for more than 1 second switches its status, which is retained even after a reboot.

      • Without UART data input: The OSD displays video information such as bitrates and stream status directly on the screen.
      • With UART data input: The OSD shows text data received from the UART interface.

      For units with firmware supporting up to 4-channel 1080P decoding and synchronous display, Ключ1 also functions as a video display switch, allowing users to toggle between split-screen multi-channel mode and full-screen single-channel mode.

Latency Performance Summary

Налаштування тесту:
The tests were conducted with the encoder and decoder boards connected directly via Ethernet cable.

Key Observations:

1. When the source signal is 1080стор.60, the end-to-end latency between the encoder and decoder is approximately 100 РС, regardless of low-latency mode, due to the direct Ethernet connection.
2. When the source signal is 4K30, the latency ranges from 270 ms to 320 РС, with slightly lower latency when the decoder display output frame rate is higher than the source signal.
3. When the source signal is 4K25, the decoder displays at 4K30. Since the decoder frame rate is higher than the source, no cumulative delay occurs, ensuring smooth playback without frame stacking.

Висновок:
The system demonstrates predictable and stable end-to-end latency under different resolutions and frame rates. Direct Ethernet connections yield the lowest latency for 1080p60 sources, while higher-resolution 4K signals naturally introduce longer delays. The decoder’s ability to output at a higher frame rate than the source ensures smooth playback without delay accumulation.
