This HDMI video to IP encoding board can view the current parameter configuration through the network port Web UI and modify it according to application needs. through the network port browser http://192.168.1.30/ (the IP address of the encoding board)

1. Please check the Web UI from the browser, at the below picture, if the video source input is ok, then it will show the CVBS or HDMI at the red arrow.

2. Please check the HDMI encoding board LED light is blink or not.
If it is green and blink, then the video input source is working well, if not blink, then please check the video input source is ok or not.

The encoding bitrate can be configured. The default web server is set to 0.0 to represent auto (3.12Mbps will be used internally). Customers can modify this value. For example, it is possible to configure 1Mbps~2Mbps or even lower.

1. We can modify the TS stream over UDP, but the TS stream is a non-standard TS stream that we have modified, which needs to be interpreted by our decoder board or special player (Download).
2. If you agree with the RTSP protocol, VLC can play it; if you only agree with the TS stream (due to our non-standard modification), VLC cannot decode and play it, so we must use our special player. (Download).
3. 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.
4. We use non-standard mpeg-2 ts streams primarily for the following reasons:
   1. The standard mpeg-2 ts stream has too much overhead outside the effective data, making it unsuitable for use with cofdm;
   2. The standard mpeg-2 ts stream is difficult to implement the aes encryption function;
   3. The standard mpeg-2 ts stream is difficult to achieve serial port transparent transmission (used with our decoder board)
5. 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
6. 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; instead, it will constantly adjust its cache (only increase but not shrink). As a result, 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.)

Yes, Sure, please contact us. 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. OK
2. The output must be playable through VLC. OK
3. UPD://@1030. OK
4. The output network stream packet should be 188 bytes standard mpeg2 TS. OK
5. Compression scheme is h. 264, CVBS PAL input and IP output. OK

How to upgrade the firmware of the CVBS PAL Analog or HDMI video input encoder board IP RJ45 ethernet output?

Sure

Please check the below link

COFDM UART AT command for the transmitter and Receiver.

Or

Download the COFDM Transmitter UART AT command PDF.

COFDM Receiver UART AT command PDF.

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.

Yes, CVBS input support NTSC and PAL, Automatic detection and adaptation

1. The 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.
2. Of course, if you want to use the parameter configuration board tool to adjust some parameters of the encoder board, it is also possible.
3. For example, the video encoding bit rate can be configured through the Web UI or changed through the extra parameter configuration board tool. The Web UI can configure all the parameters, and the parameter configuration board tool can only adjust some of them.

Ok, please check the below link

Yes, if you need, we can offer you the special firmware to have USB recorder function.

Question: Does your USB DVR support playback on the encoded video?

Answer: No, The USB has the record function. You need to play it on a computer, it can not playback on the encoder board directly.

1. Do you mean HDMI or AV input, or do you need HDMI and AV to support two simultaneous inputs?
2. Currently it supports either HDMI or AV input.
3. Vcan1746 can only choose one of HDMI/AV at present, other boards can meet the firmware you need, but this board only supports SDI + AV/AHD output.
4. If necessary, you can evaluate the board with SDI + AV/AHD input to see if it meets your requirements. If yes, our HDMI + AV input Vcan1746 can be made the same later.
5. If you really need to evaluate the HDMI + AV interface, please first buy Vcan746 and burn the default shipping firmware for testing. HDMI and AV can be selected for use. If there is a certain amount of follow-up orders, we can develop a special firmware to support HDMI+AV input at the same time.
6. 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.
7. 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.
In this way, 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.

Q: To clarify, we need HDMI, AV, and date ports. The date port should be TTL 3.3V.

A: No problem, supported.

Q: Is it possible to receive serial data on a computer without a DECODER device?

A:

1. For the players on the computer, we have RTSP (VLC or Easy player) and UDP (Splayer)
2. RTSP protocol only supports audio and video decoding. There is no serial port data decoding.
3. UDP (our custom protocol) has audio, video, and serial port transparent transmission data, but currently, Splayer only decodes the audio and video. If the customer needs serial port transparent transmission data, you must conduct secondary development based on the Splayer. (We can provide Splayer SDK)
4. If serial port data is very important for your project, then you also can use our decoder board, which support video, audio, UART serial data.

Q: Now it is working well on the VLC player by RTSP protocol. How can I use UDP at the VLC player?

A: UDP is a private and customized protocol. It can only be played at the Splayer.

Q: Yes, serial data is important to us. We can independently develop a UDP server for serial data if you provide the data format or api.

A:

1. VLC player or Easyplayer: Obtain audio and video through RTSP streaming by a universal player (VLC player or Easyplayer);
2. Special software: Interpret the data stream pushed by the encoding board UDP (including audio and video and serial port transparent transmission data) and get the serial port transparent transmission data from it.

就是客户需要通过两个途径，分别获取音视频流和串口透传数据：
1、通过通用播放器，rtsp拉流获取音视频数据；
2、通过解释编码板udp推送的数据流(含音视频和串口透传数据)，从里面解释出串口透传数据

Q: How can we see that transmitted data is working well?

A: Please check the below link.
