- If you want to switch to the standard MPEG-2 TS stream to play with VLC, our software engineer can customize the firmware for you (this will take a few days) for an additional fee of USD500.
- We use non-standard mpeg-2 ts streams primarily for the following reasons:
- The standard mpeg-2 ts stream has too much overhead outside the effective data, making it unsuitable for use with cofdm;
- The standard mpeg-2 ts stream is difficult to implement the aes encryption function;
- The standard mpeg-2 ts stream is difficult to achieve serial port transparent transmission (used with our decoder board)
- If you don't need our decoder board, encryption and serial port transparent transmission, it is also possible to use standard mpeg-2 ts stream
- It is recommended that you try our player; in real-time performance, our player outperforms vlc.
The vlc player's algorithm does not take into account real-time performance; ka, it will constantly adjust its cache (only increase but not shrink). Ko hono ola, the longer it is played, the longer the delay may be (especially when used with a wireless link)
1. SSL certificate is HTTPS protocol, our products do not support it now, only HTTP.
2. The default encoder board through the RTSP protocol, RTSP is not encrypted. You can set a longer password. And change it frequently.
3. If you want to encrypt, you need to use a pair of our codec boards (with encoder and decoder board as TX and RX), with UDP protocol, and they are using aes256 encryption. (Just like the bank level.)
'Io, Fakapapauʻi, kātaki ʻo fetuʻutaki mai kiate kimautolu. Let me list your demand at the below.
1. We need to take a composite analog PAL video signal and transmit it using h264 over MPEG2 TS. Lelei
2. The output must be playable through VLC. Lelei
3. UPD://@1030. Lelei
4. The output network stream packet should be 188 bytes standard mpeg2 TS. Lelei
5. Compression scheme is h. 264, CVBS PAL input and IP output. Lelei

Download the COFDM Transmitter UART AT command PDF.
Please follow the checkpoints below to confirm.
- After connecting the encoder board with your computer by ethernet cable, the LED of RJ45 connector should be blinking or not. (to check the ethernet connection is ok or not)
- Is your computer configured with 192.168.1.x network segment ip?
- Have you modified the default IP address of the encoding board? If the IP address changed, maybe you can download and use the below software to find what IP address now.
- Or Directly connect the UART cable of the encoding board to the computer, and use the serial port debugging assistant to send the ATGIP_ command.get ip address command Operation Video at Youtube

These parameters are determined by the camera, only the sensor has it.
One more question: In the future is there any possibility to incorporate these features in the output side of encoder (if we get volume orders) ?
Our Answer: These are the parameters of the isp, and our current encoding boards are all bypass isp (because we don't connect the sensor, we don't need and can't use the isp), so we can't add these parameters.

- Ko e parameter configuration board tool is mainly used for the COFDM module function. If you buy this HDMI / CVBS to IP encoder Vcan1746 separately, you don’t need to buy a parameter configuration board tool, you can adjust the parameters through the Web UI.

The display of HDMI and CVBS video input by two channels at the same time is similar to Hikvision IPC, which is divided into main bit rate and sub bit stream. The main stream corresponds to HDMI, and the sub stream corresponds to CVBS.
- Now we can develop a new firmware to support HDMI and CVBS to live streaming at the same time, but the audio can only be selected from one of the two (the system selects HDMI audio/analog audio according to the video access situation).
Supported.
Our HDMI and CVBS input video encoding board has a USB interface, which can be used for USB recording. It can also be used as the input interface of a USB web camera.
ʻI he founga ni, our video encoding board can convert the signal of your USB web camera into a network interface, while supporting ultra-low latency and supporting h264 and h265 encoding.
