Audio Interfaces:

• Embedded audio via HDMI and dedicated AV output connectors.
• AAC audio decoding ensures high-quality sound playback.
• Microphone input (2-pin PH2.0mm) allows live audio capture, which can be transmitted to compatible encoder modules for two-way audio communication.

Варианты хранения:

• TF (Micro SD) card slot and USB Host (Type-A) for direct recording of video streams.
• DVR functionality supports automatic recording upon device detection and manual start/stop via the onboard record key, prioritizing the TF card when both storage devices are connected.

Ethernet Input:

• 100M Ethernet port (4-pin PH2.0mm connector) supports UDP TS stream decoding, Декодирование RTSP-клиента, and optional RTSP server forwarding, enabling seamless network video integration.

Интерфейсы управления:

• Данные UART (3-pin PH1.25mm, 3.3V TTL) receives real-time data from compatible encoder modules.
• Управление UART (4-pin PH1.25mm, 3.3V TTL) allows system configuration via AT commands.
• 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 (экранное меню) 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.

  • Ключ2: Video recording control, with short presses to start/stop recording.
    • The Record key is used to start or stop video recording. A short press toggles the recording status. Upon power-on, the system automatically detects the storage device—either a TF (Micro SD) card or USB drive, with priority given to the TF card—and begins recording video if a device is present. Press the Record key at any time to pause or resume recording, providing convenient manual control over video capture.

 

Индикаторы состояния (светодиоды):

• Индикатор питания (Красный) – indicates board is powered.
• Video LED (Зеленый) – blinks when a video stream is received and decoded successfully.
• Record LED (Зеленый) – lights when recording to USB or TF card is in progress.

This combination of HDMI, CVBS, аудио, Ethernet, хранилище, and control interfaces makes the decoder board highly flexible, allowing it to support complex video monitoring setups, embedded deployments, and multi-channel streaming applications.

Please refer to the image below—the 5V output point is indicated by the red arrow. Ensure proper connection and avoid overloading to maintain stable operation.

Latency Performance Summary

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

Key Observations:

1. When the source signal is 1080стр60, 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 4К30, 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 4К30. Since the decoder frame rate is higher than the source, no cumulative delay occurs, ensuring smooth playback without frame stacking.

Заключение:
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.
