We just released a case study for Medici.tv describing how they’ve used Flash and Flash Media Server to deliver over 100 live concerts each year to a live audience of 80,000 each time. They launched the service back in May 2008, and have served 3.4 million free live webcasts of concerts from around the world.
If you haven’t seen this experience, you have to visit their site: http://www.medici.tv/. As soon as you reach the site, you get full-browser video with interactive overlays, that let you browse details about the concert, and search their site – without leaving the experience. The sound quality is great, and so is the video quality.
Here’s a screenshot
The streams are encoded from 500kbps through to 1.2Mbps from HD cameras encoded using Kulabyte Xtreme. The quality looks great in both fullscreen, and in the browser.
