Web UI management Parameter setting

1. Cal é o enderezo IP predeterminado deste codificador de HDMI a IP?

Esta placa de codificación de vídeo HDMI a IP pode ver a configuración actual dos parámetros a través da IU web do porto de rede e modificala segundo as necesidades da aplicación.. a través do navegador de portos de rede http://192.168.1.30/ (o enderezo IP da placa de codificación)

2. Como comprobar o posible problema se a saída do codificador non funciona?

1. Comprobe a IU web desde o navegador, na imaxe de abaixo, se a entrada da fonte de vídeo está ben, then it will show the CVBS or HDMI at the red arrow.

2. Comprobe que a luz LED da placa de codificación HDMI parpadea ou non.
Se é verde e parpadea, entón a fonte de entrada de vídeo funciona ben, se non pestanexa, then please check the video input source is ok or not.

3. How can I modify the compression bitrate?

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. Por exemplo, it is possible to configure 1Mbps~2Mbps or even lower.

4. How to set the GOP？

GOP is required to be set to an integer multiple of the encoding frame rate (note that it is the encoding frame rate):

1. Por exemplo, if the camera inputs 1080P60, then the gop is set to 60/120/180 (it is not recommended to set too large)

2. Por exemplo, if the camera inputs 1080páx 25, the gop is set to 25/50/75 (it is not recommended to set too large)

3. Por exemplo, the camera input 1080i60, due to the need for de-interleaving, all the actual encoding is 1080p30, then the gop is set to 30/60/90

If your video source is CVBS, CVBS has two systems, PAL is 25fps, NTSC is 30fps

if your CVBS is PAL, then GOP set is 25/50/75, if your CVBS is NTSC, then GOP set is 30/60/90.

o larger the gop setting, the better the image quality, but the size difference between the I frame e o P frame becomes larger, resulting in the following disadvantages:
1. Large I-frames are prone to frame loss due to wireless transmission;
2. If the gop setting is large, the loss of the I frame will lead to a longer recovery time after the blurred screen;
3. The size difference between I frame and P frame is large, which will increase the transmission delay.

gop要求设置为编码帧率的整数倍(注意是编码帧率)：
1、比如相机输入1080p60，那gop设置为60/120/180(不建议设置太大)
2、比如相机输入1080p25，那gop设置为25/50/75(不建议设置太大)
3、比如相机输入1080i60，由于需要去交织，所有实际编码是1080p30，那gop设置为30/60/90
从上面可以看到，由于输入相机帧率不确定，所以我们一般建议配置0(automático)
cvbs分制式，pal是25fps，ntsc是30fps
假设是pal，那gop设置25/50/75

gop设置越大，画质越好，但是I帧和P帧的大小差别变大，产生一下缺点：
1、大的I帧容易因为无线传输的原因导致丢帧花屏；
2、gop设置大，I帧丢失导致花屏后恢复时间变长；
3、I帧和P帧大小差别大，会增加传输延迟

5. Where can I download the UDP player? We recommend Splayer_v4.2_2020.6.6 which we use frequently.

Please download at the below link.

6. Is mpeg-2 TS over UDP supported? Instead of RSTP, i need MPEG-2 Transport stream.

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 (Descargar).
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. (Descargar).
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; en cambio, it will constantly adjust its cache (only increase but not shrink). Como resultado, the longer it is played, the longer the delay may be (especially when used with a wireless link)

7. Do you have any SSL certification or code signing certification to protect your HDMI AV encoder board?

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.)

8. Do you offer customized firmware for me?

si, Claro, póñase en contacto connosco. 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

10. Can you make the PCB size to 40x40mm?

grazas.

Only CVBS composite video input, we once designed and produced 42x37mm, CVBS composite video source to IP encoder board. (No HDMI input)

If both CVBS and HDMI video input, we can not make it smaller. Except that you allow the use of two PCB boards stacked.

11. What should I do if I can't ping the encoder board from my computer?

Please follow the checkpoints below to confirm.

1. 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)
2. Is your computer configured with 192.168.1.x network segment ip?
3. 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.
   https://www.advanced-ip-scanner.com/
4. Or Directly connect the UART cable of the encoding board ao ordenador, and use the serial port debugging assistant to send the ATGIP_ command.get ip address command Operation Video at Youtube

12. Is it possible to control/modify DNR, Sharpness, contrastar, Balance de branco, etcétera?

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.

13. Does the composite video input support both PAL and NTSC standards?

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

14. Should I buy the extra parameter configuration board tool for this HDMI / CVBS to IP encoder?

1. o 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. Por suposto, if you want to use the parameter configuration board tool to adjust some parameters of the encoder board, it is also possible.
3. Por exemplo, 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.

16. Do this encoder module board has recorder function via USB or TF card?

si, se precisas, we can offer you the special firmware to have USB recorder function.

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

resposta: non, The USB has the record function. You need to play it on a computer, it can not playback on the encoder board directly.

17. We will use it with two inputs (HDMI e PAL) and with 12V, Can you confirm it's working?

1. Refírese á entrada HDMI ou AV, ou necesitas HDMI e AV para admitir dúas entradas simultáneas?
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 + interface AV, 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, pero o audio só se pode seleccionar entre un dos dous (o sistema selecciona audio HDMI/audio analóxico segundo a situación de acceso ao vídeo).

18. Does your video encoding board support USB web cameras?

Soportado.

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.
