How to Transmit UART Data with HDMI+CVBS Encoder Boards

Many customers want to transmit 동영상, 오디오, and UART data using our encoder boards. Here’s a clear guide on what’s possible, the limitations, and the best way to achieve it.

1. Current Status of HDMI+CVBS Encoder Boards

특색	HDMI+CVBS Encoder Board
Serial tab in web UI	❌ Not available
UART data transmission	❌ Not available by default; 사용자 정의할 수 있습니다
Video/Audio Protocols	✅ RTSP (video/audio only) ✅ UDP (supports video/audio + UART if used with decoder)

Key point: The encoder board alone cannot decode UART data on a PC with VLC or other generic players. You need our paired decoder board.

2. How UART Data Transmission Works

1. Encoder Board
   • Accepts UART data input for transmission (UDP only).
   • RTSP stream is video/audio only; UART data cannot be sent via RTSP.
2. Decoder Board
   • Required to properly decode UART data from the encoder.
   • Generic video players (예를 들어, VLC) cannot decode UART data.

Illustration of Setup:

PC ---Ethernet---> HDMI+CVBS Encoder Board ---UDP---> Matching Decoder Board ---> UART Data Output

3. 대안: 의 (CVBS) Input with UART

If you are using 의 (CVBS) 입력, you can use our dedicated converter board:

CVBS/AV Video to Ethernet IP Video Stream Converter Board

특색	의 (CVBS) Converter Board
HDMI 입력	❌ Not supported
UART data input	✅ Supported
Data retrieval on PC	✅ TCP protocol

팁: This is ideal if you only need UART + CVBS video streaming, and want to receive UART data directly on a PC.

4. Recommendations

• HDMI+CVBS input + UART: Must use both encoder and matching decoder.
• 의 (CVBS) + UART: Use the AV converter board with TCP to retrieve UART data on PC.
• Do not expect VLC or generic players to decode UART data; they only handle video/audio streams.

결론:
Our encoder boards can transmit UART data, 하지만 only with the matching decoder or the AV converter board. Understanding these options ensures you pick the right board for your system and avoid confusion or failed setups.
