At its central headend in Anchorage, GCI is using RGB's TransAct to transcode video of the Iditarod in real-time from MPEG-2 to the MPEG-4/H.264 for streaming to PCs over the Internet. GCI is also creating multiple individual streams at different screen resolutions and bit rates to accommodate the wide variety of PCs and broadband speeds used by GCI's subscribers. Finally, GCI is packaging the individual streams into the Microsoft Smooth Streaming video delivery application.
The Iditarod Trail Sled Dog Race covers more than 1,000 miles of Alaska and can take as long as 15 days to complete. The race has been held since 1973.
