Less than two months away from the beginning of the summer Olympics, NBC has yet to announce their complete technology plans for the games. Here’s what we know:

• Microsoft paid a hefty portion of NBC’s development costs to get them to use Silverlight, and is still working to remove the beta from Silverlight 2.0 ahead of the summer games.
• Microsoft demoed the NBC Olympics site at Mix08, announced the same day that they had formed a strategic relationship with Move Networks, and Move’s CEO hinted late last year that the company would be involved.
• The player was designed by Schematic, the Los Angeles based design company with strong ties to Move Networks. More than 2,200 hours of live video and more than 3,000 hours of on-demand content will be offered through NBCOlympics.com on MSN.
• NBC will use a Media Asset Management System from Blue Order.
• NBC will limit its downloadable ‘On the Go’ Olympic video on-demand service to users running Microsoft Vista. The service, powered by Wavexpress will allow media center users to view downloaded content in up to HD quality, protected by DRM.

The missing piece is the most important part - the live content delivery portion. Clearly NBC and Microsoft will need some very large partners to deliver a live event of this scale efficiently and it seems strange that the company has made so many separate announcements about without any insight into their technology partners and other plans for live.

Burning questions: Who is handling encoding and content delivery? Will there be a login required? How will advertising be integrated and who is managing it? How many concurrent viewers do they anticipate and how many can they support? How will they manage access in order to deliver a high quality of experience for all users? It is not a good sign that these questions are still unanswered so close to the start of the games.

NBC Universal did not respond to e-mailed requests for comment.
