RTVideo

This article is about Microsoft's VC-1 based codec. For Intel's Real-Time Video (RTV) codec, see Digital Video Interactive.

RTVideo is Microsoft's default video codec for Office Communications Server 2007 and the Microsoft Office Communicator 2007 client. 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.

Licensing

RTVideo is a proprietary codec. Like RTAudio this protocol can also be licensed from Microsoft.
