How to Transmit UART Data with HDMI+CVBS Encoder Boards

Many customers want to transmit वीडियो, ऑडियो, 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

विशेषता	HDMI+CVBS Encoder Board
Serial tab in web UI	❌ Not available
UART data transmission	❌ Not available by default; अनुकूलित किया जा सकता है
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. एनकोडर बोर्ड
   • Accepts UART data input for transmission (UDP only).
   • RTSP stream is video/audio only; UART data cannot be sent via RTSP.
2. डिकोडर बोर्ड
   • Required to properly decode UART data from the encoder.
   • Generic video players (जैसे, वीएलसी) cannot decode UART data.

Illustration of Setup:

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

3. विकल्प: का (CVBS) Input with UART

If you are using का (CVBS) इनपुट, you can use our dedicated converter board:

CVBS/AV Video to Ethernet IP Video Stream Converter Board

विशेषता	का (CVBS) Converter Board
HDMI इनपुट	❌ Not supported
UART data input	✅ Supported
Data retrieval on PC	✅ TCP protocol

Tip: 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 + यूएआरटी: Must use both encoder and matching decoder.
• का (CVBS) + यूएआरटी: 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.

निष्कर्ष:
Our encoder boards can transmit UART data, लेकिन 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.
