Microsoft Portrait is a research prototype for mobile video communication. It supports .NET Messenger Service, Session Initiation Protocol and Internet Locator Service on PCs, Pocket PCs and Handheld PCs. It runs on local area networks, dialup networks and even wireless networks with bandwidths as low as 9.6 kilobits/second. Microsoft Portrait delivers portrait-like video if users are in low bandwidths and displays full-color video if users are in broadband. In low bandwidths, portrait video possesses clearer shape, smoother motion, shorter latency and much cheaper computational cost than do conventional video technologies. Microsoft Portrait provides presence notification, chat/voice/video functions almost anytime, anywhere, on any device.
Microsoft Portrait enables two-way full-color video conferencing on PCs, Pocket PCs and Handheld PCs. This means with Microsoft Portrait, a Pocket PC or Handheld PC can not only receive and display full-color video, but also capture and send full-color video in real-time
