Webcasting
Commonly used in Media/Communication
Webcasting is the process of broadcasting live audio and video content over the internet, allowing audiences to access the stream in real-time through computers or mobile devices. It enables content creators to reach large, geographically dispersed audiences without the need for physical venues or traditional broadcast infrastructure.
How It Works
Webcasting involves capturing live audio and video signals through cameras, microphones, and encoding devices. These signals are then compressed into digital formats suitable for streaming. The encoded data is transmitted over the internet via streaming servers, which distribute the content to viewers' devices. Viewers access the webcast through web browsers or dedicated applications, with the content delivered in real-time, often with minimal latency. Technologies such as Content Delivery Networks (CDNs) are used to optimise distribution, reduce buffering, and ensure smooth playback regardless of the viewer's location.
