What equipment will be used for outdoor live broadcast
Now more and more anchors are keen to go live outdoors, in order to play more new tricks and attract more viewers. What should we do if the outdoor live broadcast signal is not good and unstable?
Many people are already familiar with routers. After all, it is the age of the Internet. The network is ubiquitous, and the router, which is a kind of connection device for the network, has long been familiar and used. But the routers that many people come into contact with are just ordinary routers (home or enterprise). In fact, there is also a broadcasting-grade "4G multi-card aggregation router". Let me introduce it in detail below:
The 4G multi-card aggregation router can aggregate the bandwidth of multiple Internet links, which can not only increase the uplink and downlink network bandwidth in a mobile environment, but also because the device supports simultaneous insertion of SIM cards from different operators, reducing mobile network signal blind spots and improving network availability . It can provide stable communication guarantee when the network is bad. High-quality live video and video return can be carried out.
The router unpacks the front-end data and sends it to the aggregation server through multiple SIM card networks at the same time. The aggregation server restores the data and then forwards it to the target server; in the use scenario where the three operators aggregate, the number of available 4G base stations is at least Doubled to reduce blind spots in network coverage. Users can use the networks of three operators at the same time, and the number of base stations served is twice that of a single China Mobile user, 3.45 times that of a single China Telecom user, and 4.77 times that of a single China Unicom user.
4 major features of multi-card 4G aggregation router
1, high traffic :
Emergency events often occur in places with severe signal attenuation or crowded people, and the communication capacity of a single link will drop sharply. In this case, it becomes extremely difficult to achieve rapid transmission of large-volume information on a single link. This solution can be aggregated Multiple small-capacity channels form a large-capacity channel. According to the structure of the front-end communication module, it can be divided into 4 times expansion, 8 times expansion, and 16 times expansion mechanisms. Not only that, the information transmitted by this device is transmitted via different links, realizing the relatively orderly arrival of real-time information flow, and avoiding information interruption due to timeout waiting and other reasons.
2. High stability:
The expansion from single link to multi-link aggregated transmission improves the stability of emergency communication. Adopting an unreliable transmission mechanism, the front end does not need to wait for back-end information feedback, so the instantaneous jitter of a link can be detected within 5ms, and the front-end transmission data can better optimize the link and configure the load, thereby effectively avoiding it Link congestion caused by blind data transmission, maximize use of all available channels to form a stable communication link. The device also provides a forward error correction mechanism, with a fault tolerance rate of 5%-75%, and back-end restoration of irresistible packet loss by configuring a reasonable redundant packet to further reduce possible data packet loss and further improve stability.
3. High security:
Another natural advantage that single link expansion brings to multiple links is: data security. First of all, after unpacking the original data of the information flow, it does not load each link according to a determined distribution ratio, but uses the actual transmission capacity of each link within 5ms as the only load principle, each within each 5ms The amount of data transmitted by the link is changing, so it is difficult for a data stealer to capture and analyze a single link; secondly, because the original data is transmitted via different physical links, the data of a single link is incomplete Yes, even if an illegal user intercepts the data, there is no availability; again, because an indeterminate amount of redundant data is configured, it is difficult to parse the data unless it reaches the end point.
4. High convenience:
This equipment brings maximum convenience to front-line users. The front-end equipment is only equipped with one switch key, and other configurations are adaptive. Whether it is a vehicle-mounted system or a single-soldier system, the personnel can start communication support within 10 seconds. In short, the "4G multi-card aggregation router" is a mobile access device with high throughput, high stability, high security, high convenience, and outstanding technical advantages. Through multi-network aggregation, a high-bandwidth network can be brought to the scene to ensure the continuity and high quality of the live broadcast. In addition: it is easy to carry, has strong endurance, and can be connected to major live broadcast platforms, so it has become the choice of many professional live broadcast teams.
