How to choose a professional and stable wireless 4G aggregate encoder

The continuous development of new media is changing the lifestyles of more and more audiences. Whether it is corporate events or outdoor programs, weddings, parties, events, etc., we want to record this beautiful moment through live broadcast. At present, there are generally two live broadcast methods, one is mobile phone live broadcast, and the other is professional live broadcast equipment. Mobile phone live broadcast is suitable for small occasions, simple live broadcast with goods, mobile phone live broadcast is simple to operate, shooting angles, and presentation pictures do not need to be diversified. Camera live broadcast mainly realizes live broadcast through cameras, usually used for talk show live broadcast, event live broadcast, conference live broadcast, school teaching live broadcast, sports event live broadcast, etc.; for professional outdoor live broadcast, how to choose professional and stable wireless 4G aggregation coding Where's the device?

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.

H.265 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.
