How does a webcast differ from a video conference, and why can technical difficulties quickly arise? Learn about the causes and possible solutions and find out how to turn your webcast into a scalable live event.
Streaming video has been a growing trend in our daily lives for years. More and more companies are opting to hold formats such as town hall meetings, e-learning sessions, or team events in a hybrid format or fully digital. Video broadcasting offers many advantages:
In our eCDN Data Sheet you can read all about how an eCDN works, what benefits it offers and how it can make your live events scalable and a great success.
Webcasting: Definition & Challenges
The term webcast describes a live transmission specifically via the Internet and comprises the terms broadcast (i.e., transmission, broadcast) and web. Unlike a conventional videoconference, in which a few participants can gather and interact with each other, a webcast is aimed at significantly more viewers. Such a one-to-many video broadcast is ideal for lectures or town hall meetings, for example. However, due to many viewers, a webcast also poses different technical challenges than a video conference.
What happens during the transmission of a webcast?
Video conferences or live streams with a few participants often work without any problems. However, the more viewers join a video stream, the more data traffic is exposed to the network. The limit is quickly reached:
The amount of data moving through the company network plays only a subordinate role. What is decisive is the amount of data that has to enter the company network simultaneously. This is where a bottleneck occurs, which can cause failures of the entire network. The so-called bottleneck problem is the cause of symptoms such as:
Scalable video streams thanks to P2P eCDN
To solve the bottleneck problem, congestion at the entry point to the network, i.e., a high simultaneous data load, must be avoided. This can only be done by simply requesting less data at the same time on the network. The solution is an enterprise Content Delivery Network (eCDN). A peer-to-peer (P2P) based eCDN, like StriveCast’s, works by creating a dynamic network between all users who want to access a video stream. These users then begin sharing the stream data with each other once they enter the network, rather than downloading it separately from a server outside the intranet. This takes a massive load off the firewall and allows the available bandwidth to be used much more efficiently.
An eCDN can ensure that digital events are possible even with many viewers without fearing poor video quality, long buffering, or even an entire network collapse.
