Path 1 Network Technologies Inc. will extend its support for high-definition video-over-Internet Protocol with a multiport, bidirectional system to be shown at the National Association of Broadcasters conference in Las Vegas. The system, dubbed vidXwan, is based on Intel Corp. network processors and embeds Path 1's proprietary forward-error-correction (FEC) technology in a 1RU package.

The product will be one of the first to comply with the Pro-MPEG Forum's code of practice on FEC and transport architectures, said David Carnevale, VP of marketing at Path 1. The gateway takes ASI transport input traffic, encapsulates its video streams and converts them to IP, and interfaces with standard switches or routers in an IP network.

Vyvx used Path 1's first-generation unidirectional Cx1000 video gateways to transport primary and secondary feeds of high-definition video during the Super Bowl. Vyvx used a 270Mbps multiprotocol label-switched fiber network to transport IP traffic that had been packetized and synchronized by the Path 1 gateway. In early April, Cox Communications Inc. announced that it would use the Cx1000 to telecast 150 sports events in HD format in the San Diego area, including several San Diego Padres baseball games.

The vidXwan is intended for transport streams in the 40Mbps to 45Mbps range. It can be used as a feed for Gigabit Ethernet-enabled switches, and Path 1 said that future systems may support 10Gb Ethernet switches. "Many European customers [are] still using Fast Ethernet, so we wanted to offer a product right for the mainstream of IP transport tasks before scaling up for 10Gb Ethernet support," Carnevale said.
