Furthermore, HTML5 video players can be easily styled and customized using CSS and controlled programmatically with JavaScript, offering web developers flexibility in integrating video content into their web applications.
Why is a CDN important for live streaming?
A Content Delivery Network (CDN) plays a crucial role in live streaming by enhancing the quality, reliability, and reach of the broadcast. Here’s why a CDN is important for live streaming:
Global Reach and Scalability: CDNs have a geographically distributed network of servers, which means they can deliver content to viewers worldwide with minimal latency. This global footprint ensures that a live stream can reach a wide audience without geographical limitations and can scale up to accommodate spikes in viewer numbers, maintaining a smooth viewing experience for everyone.
Reduced Latency: One of the biggest challenges in live streaming is minimizing latency, which is the delay between the live action being captured and displayed to the viewer. CDNs reduce latency by caching the stream on servers closer to the viewer, ensuring that the content travels a shorter distance over the internet. This is especially important for real-time interactions during live events.
Load Balancing: During high traffic periods, a CDN can distribute the load across its servers, preventing any single server from becoming overwhelmed. This load balancing helps in managing large volumes of traffic efficiently, reducing the risk of buffering and ensuring that the live stream remains uninterrupted.
