CNET a un excellent article sur l'utilisation de Silverlight par NBC pour retransmettre les JO.
From each of the dozens of Olympic venues, a high-definition video feed is delivered over fiber-optic cables to the International Broadcast Center that has been set up in Beijing. A bunch of encoders and Windows Media servers get the video into an Internet-ready format. From there, it travels via satellite to NBC's headquarters in New York. There, NBC actually adds a one-minute delay, allowing its cadre of live bloggers in Stamford, Conn., and elsewhere to write their text and have the video and commentary synchronized.
