LoneStarCon 3 has been working with Ustream to prevent a repetition of the unfortunate situation last year when one of Ustream's 'bots determined that the clips of Hugo Award nominated dramatic presentations were copyright violations and shut down the live feed. That was in no small part because we were using Ustream's free and ad-supported services, which are more prone to such takedowns. Ustream and LSC3 are working together to make sure that doesn't happen this year.
The Ustream and CIL feeds are not synched in any way. CoverItLive is relatively low bandwidth. If your connection isn't fast enough to handle the streaming video, you can watch us describing the action as it happens in San Antonio. Based on our past experience, the CIL feed can get several minutes ahead of the video, similar to how the radio and television coverage of the same sporting event are rarely in synch with each other. Indeed, the CIL coverage is analogous to the radio coverage of a sporting event, while Ustream is the television coverage.
I've had people say, "if you have live video, then why bother with the CIL stuff?" Well, returning to the sports analogy, the fact that it's possible to watch a baseball game on television didn't kill the need for radio broadcasts of the same event. Also, because Ustream is high-bandwidth and is a resource hog, lots of people just can't use it. Also, the CIL coverage allows moderated discussion of the events as they come in.
Speaking of moderators, while Mur Lafferty and I will be "calling the action" from the auditorium in San Antonio, our Studio Coordinator and the third member of our coverage team is Cheryl Morgan, who will be up in the wee hours of the morning in Wiltshire moderating the coverage and contributing her own thoughts to the event as it happens. Cheryl is the person who effectively created the CIL-casts in the first place, when she recruited Mur and me to cover the 2010 Hugo Awards for SF AwardsWatch.
I hope that if you can't make it to San Antonio to see the Hugo Awards ceremony that you'll watch it live on video or join Cheryl, Mur, and me for the call of the action from the Grand Ballroom as WSFS presents its highest honors.
