Company to Demonstrate Broad Range of IPTV Products That Deliver Optimized Video QoS over the Internet SAN DIEGO, March 13 /PRNewswire-FirstCall/ -- Path 1 Network Technologies Inc. (AMEX:PNO), a leading provider of IP video gateway products that enable the transmission of broadcast-quality video over IP networks, announced today a complete range of product and broadcast application demonstrations for NAB 2006. Path 1 will highlight its award-winning Vx8000 multi-port IP video gateway with ClearPath Pro forward error correction (FEC) technology, an extension to the Pro-MPEG COP #3 standard. ClearPath Pro FEC is specifically designed to transport high-quality, real-time video over the Public Internet. Additionally, Path 1 will demonstrate its Cx1020 SDI over IP video gateway and its professional services tools designed to monitor, find and fix network anomalies that commonly occur and degrade video transmissions over public and private IP networks. With Path 1's reliable technologies and tools, broadcasters and operators will benefit from the cost savings of leveraging the Public Internet, as well as the scalability and flexibility it provides in broadcast video contribution. These technologies will be shown at NAB 2006 in Path 1's booth #C9535, located in the Central Hall of the Las Vegas Convention Center the week of April 24-27. "The COP #3 FEC standard addresses the performance needs of private IP networks. However, the public Internet presents an entirely different challenge in terms of high-quality video transport, but is one that Path 1 has been able to overcome," said Rick Segil, vice president of marketing at Path 1. "We've added our patented ClearPath Pro FEC techniques to the COP #3 standard in order to specifically address video over Internet issues, such as delay, jitter, packet loss, and out-of-order packets delivery. With these advancements, Path 1's customers can leverage affordable shared Public Internet bandwidth for delivering new services, such as IPTV and HDTV. In many cases, our customers can use their existing IP network connections, which previously carried only voice and data, to also transport video worldwide." About Path 1's IP Video Gateways With a 60x increase in FEC performance, Path 1's Vx8000 combines support for standards-compliant Pro-MPEG COP #3 with Path 1's proprietary high- performance encapsulation and forward error correction (FEC) technology called ClearPath Pro. Both forms of FEC are included in the same product and are user-selectable based on the appropriate network environment. As a result, the Vx8000 can overcome the types of losses/outages that routinely occur over any type of IP network, including the Public Internet. Path 1's Cx1020 IP Video Gateway with ClearPath FEC is capable of handling ASI and 270 Mbps SDI/SDTI video. The Cx1020 is also available with Path 1's RepliCaster(TM) stream replication technology, which is ideal for point-to- multi-point video transport over IP/MPLS networks. Both the Vx8000 and Cx1020 enable broadcasters to deliver real-time, broadcast-quality MPEG-2, MPEG-4 and VC-1 (MPEG-2 TS) video in Standard (SD) and High Definition (HD) formats. About Path 1's Professional Services Tools Monitoring and analysis tools are also instrumental to delivering broadcast video over IP, since they provide the metrics and intelligence about network conditions. Path 1's evaluation and analysis tool enables network administrators to visualize and determine the condition of IP networks and their ability to transport perfect video, including measuring the right amount of FEC required in a network to eliminate video packet loss and reduce time to deployment. With these analysis tools, Path 1 provides the ability to monitor networks, find anomalies and propose fixes to improve network performance and overall video quality.
