It is a Microsoft proprietary implementation of the VC-1 codec for real-time transmission purposes. Microsoft extensions to VC-1 are based on cached frame and SP-frame. Also it includes system-level enhancements for recovery of packet loss on IP networks - forward error correction and error concealment.
