How to use 4G encoder for streaming

What is the 4G encoder for?

The 4G encoder is a professional outdoor live streaming device. The 4G live encoder uses a 4G network and is usually used for outdoor live broadcasts, outdoor event live broadcasts, event live broadcasts, outdoor events, etc.

The final result of the 4G live encoder is to push the pictures of our live broadcast to the live broadcast platform, the more common network cable transmission, WIFI signal transmission and mobile phone (4G) card signal transmission and so on.

For outdoor live broadcast application requirements, it is inevitable to be outdoors where there is no network cable, so 3G/4G/5G networks need to be used to transmit live broadcast signals to the broadcast platform. How to use 4G encoder to push streaming?

How does 4G encoder push streaming?

The first step: equipment installation and connection

The P series 4G encoder has two interfaces: SDI and HDMI. First connect the video signal, and connect the SDI/HDMI signal from the signal source (such as a camera) to the input port of the device through a cable.

Then connect to the network, plug the USB to RJ45 network port cable into the USB port of the device, connect the network port to the switch, or directly connect to the network port of the computer.

Note: First, connect the encoder to the same switch with the computer via USB to RJ45, or directly connect the encoder to the computer network port. Then configure the encoder and computer to the same network segment so that the computer can access the encoder's WEB page. The default management IP of the encoder network port is 192.168.1.168.

Step 2: Device network configuration

The 4G encoder has a built-in 4G module, and it can also be directly inserted into a SIM card to connect to a 4G network. Because it does not support SIM card hot swapping, you need to insert the SIM card before turning on the device.

Step 3: Add streaming service

After the network is set up, find "H.264 main stream" on the encoder WEB management page, add the stream service, and then copy and paste the push stream address into the stream service in the background of the live broadcast platform. Currently, most live broadcast platforms support RTMP streaming protocol.

Note: The principle of RTMP streaming is to push the stream from the encoder to the platform, and the computer/decoder then pulls the RTMP stream from the platform for playback. The encoder cannot directly push the RTMP stream to the computer/decoder for playback.

Step 4: Watch

Scan the QR code through the platform website or mobile phone to watch online. If you need to pull the video stream of the live platform to the local area, the platform must be able to provide the streaming address. Only some specific platforms can support it.

So, how to choose a professional and stable 4G wireless encoder?

1. Video input interface

Now the video transmission interface of the camera is basically SDI interface and HDMI interface, so as a streaming device, you must ensure that the two interfaces are complete.

2. Coding method

Video coding is the core of a live streaming encoder. Choose equipment with professional coding chips as much as possible to ensure that the live broadcast has clearer picture quality, richer colors, and more three-dimensional pictures.

3. Network adaptability

The final result of the live streaming encoder is to push the live images of our live broadcast to the live broadcast platform, so multiple network interfaces are essential. The more common network cable transmission, WiFi signal transmission and mobile phone (4G) card signal transmission and so on. Because our live broadcast is inevitably outdoors where there is no network cable, and the direct transmission of the live broadcast signal to the broadcast platform through the mobile phone card will solve a major problem of outdoor live broadcast.

4. Transmission stability

Multi-network aggregation function-aggregating multiple signals to enhance the stability and safety of signal transmission, just like a highway from 2 lanes to 4 lanes or even 8 lanes.

Real-time screen monitoring function-real-time monitoring of the current network signal status, equipment working status, screen transmission status, etc. is normal and stable. Once an abnormality occurs, it can be solved immediately to avoid live broadcast jams, black screens, bad pictures, etc.

Self-contained power supply-When broadcasting live outdoors, not only the network is needed, but more importantly, a power supply that can be used for a long time. Under normal circumstances, a live broadcast is often about 2 hours. If there is an encoder that can support an ultra-long working time of 3 hours, it can really add to the outdoor live broadcast.

Thousands Vision P series aggregate encoder integrates all the above functions, adopts H.265+ low bit rate and high image quality coding technology to ensure excellent image quality transmission in poor signal areas, built-in lithium battery power supply, and also supports 5- 16v external mobile power supply, no need to consider wired power supply; with active heat dissipation design, adapt to outdoor high temperature or sun exposure operating conditions, stable and reliable operation. Therefore, Qianshi's portable 4G multi-card live encoder is very practical and professional outdoor live broadcast equipment.
