The United States Tennis Association (USTA) is offering tennis fans, live streaming of the 2009 US Open from the Arthur Ashe Stadium. The interactive HD streaming is further enhanced by the offering of a picture-in-picture feature and real-time stats.

The site also leverages IBM’s Flash powered Slam Tracker, which lets users track player progression, schedules and scores for the entire tournament. Slam Tracker’s scoreboard “pushes” point-by-point scoring, live draw results, match and serve stats, player information and tracking, as well as interactive venue maps and live streaming radio.

The Ultimate Fighting Championships (UFC) are going to start trialing a new streaming service powered by Silverlight, and Internet Information Services (IIS) Smooth Streaming, for UFC #102 on August 29th.

They are still using Flash Media Server for streaming pre-recorded and live events, and have added Silverlight to their streaming client arsenal, in an effort to to reach the broadest possible audience.

A new white paper has been released, onto the Adobe Developer Center, that presents Adobe Flash Media Server content protection features and best practices, and introduces Adobe Flash Media Rights Management Server.
