PALO ALTO, Calif.--(BUSINESS WIRE)--June 28, 2001

Amnis Systems, Inc., (formerly Optivision, Inc.), a leading global provider of networked streaming video systems, announced today support for the Real Time Streaming Protocol (RTP) in its network attached streaming video appliance products. Widely supported by the network industry, RTP has become a standard for transport of real time data including audio and video in broadband IP based networks.

Using RTP, Amnis provides an end-to-end solution for transmitting and receiving high quality streaming MPEG video over enterprise networks. RTP has been integrated into Amnis Systems' network attached NAC(TM)-3000 live streaming video server and NAC-4000 video receiver products. RTP can be selected as an alternative transport mechanism for streaming MPEG-1 or MPEG-2 compatible digital video in broadband IP based networks. As a thin protocol RTP provides support for continuous media and includes functionality for timing reconstruction, packet resequencing and content identification with minimum network overhead. These features allow the NAC-3000 and NAC-4000 to adjust to typical IP network variations to insure a continuous flow of video.

Amnis pioneered the network attached video appliance market with its introduction of the NAC series products two years ago. These products integrated industry standard network protocols with high quality MPEG video data streams to enable the first MPEG video over IP enterprise applications. "We are responding to clear network technology trends and demand from our customers who now have a complete end to end solution interoperable with their RTP enabled network infrastructure," said Michael Liccardo, chairman, president and CEO of Amnis Systems. "The enterprise market is continuing to expand its use of video over IP applications and Amnis' RTP support further expands our industry leadership and market momentum."

Amnis' network attached streaming media systems provide essential network infrastructure, hardware and software, for high quality streaming video applications. The interoperable components are optimized for network attached streaming video applications and enable enterprises to transmit, receive, play, and record live and stored video content that meets both the Moving Picture Experts Group (MPEG)-1 and MPEG-2 industry standards, without requiring costly modifications to network infrastructure. Amnis' modular plug-and-play platform allows fast deployment and offers organizations the scalable tool they need to easily exploit the full potential of their existing broadband networks to enable a full range of collaborative multimedia applications, including distance learning, corporate communications, content distribution, e-commerce, telemedicine, and surveillance.
