Microsoft Portrait now supports .NET Messenger Service, Session Initiation Protocol (SIP) and Internet Locator Service (ILS) on PCs, Pocket PCs and Handheld PCs. You can chat or call with Microsoft Portrait users or MSN Messenger users after you sign in .NET Messenger Service or Communications Service.
Microsoft Portrait is a research prototype for mobile video conferencing. 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 basic presence notification, chat/voice/video functions almost anytime, anywhere, on any device.
