Unmatched ease of access

Smooth Streaming uses the standard downloading of HTTP files for easy connection to video streams, even through firewalls, as if they were just another Web page. Video streams can also be cached in existing servers on Level 3’s global Content Delivery Network to allow a massive diffusion of the service on the Internet. This is all monitored from the Level 3 Broadcast Operations Centre.

The Silverlight application developed to read the flows is capable of dynamically detecting that CDN Level 3 flows are available and can switch between them without any breaks. Silverlight can also modulate the quality of the flow according to the condition of the client computer. This means Web users who have broadband connections can enjoy 720p HD images, while users with low-rate connections or less powerful computers receive a flow that is better suited to the quality of their connection.clip_image002_thumb
