IBC 2002

SAN DIEGO--(BUSINESS WIRE)--Sept. 11, 2002

Path 1 Network Technologies Inc. (OTCBB:PNWK)(Frankfurt:PNT), a leader in delivery of broadcast quality video over IP networks, announced today it will head a demonstration featuring the interoperability over IP of MXF file format and live video transmission as part of the Pro-MPEG Forum Interoperability Centre in Hall 3, Booth 3.101 at the International Broadcasting Convention (IBC), which opens this week in Amsterdam at the RAI Center.

The demonstration features Path 1's existing VoD and long haul products and will also mark a first preview of its Cx1800 series VOD product, an ASI to IP x-y router supporting up to 1 gigabit of IP and up to 8 DVB ASI ports for the VOD marketplace.

"As part of Path 1's key role in the WAN committee of the Pro-MPEG Forum, we will provide both a gigabit and 100 megabit link on which real-time video servers, non-linear editors, MPEG encoders and decoders can interchange material seamlessly," said David Carnevale, vice president, marketing & sales for Path 1.

Participating companies include SeaChange, Sony, Panasonic, Quantel, Leitch, Avid, Cisco, British Broadcasting Corp. (BBC), European Broadcasting Union (EBU), British Telecom (Btexact) and others.

"Path 1 has led the deployment of both cable and broadcast content delivery over IP networks and is helping to establish standards that enable broadcasters to use flexible IP networks to dynamically exchange information and entertainment content," stated Carnevale, on location in Amsterdam.

Specifically, the Path 1 Cx1000 gateway brings error-corrected broadcast quality transport of SDI/SDTI and MPEG (DVB ASI) over long-haul networks to support central casting, remote contribution, and program distribution. The Cx1000 has been designed to effectively handle delay, jitter, packet losses, and out-of-order packets on IP networks ensuring high Quality of Service (QOS) over existing SONET, SDH, and frame relay backbones.

In addition, Path 1 will showcase the Path 1 Cx1410 multiplexer, which brings IP VoD transport to reality over existing cable infrastructures. The unit aggregates up to 200 MPEG programs over gigabit Ethernet into four MPTS ASI streams and is being deployed by a variety of cable operators today. The output is fully compatible with existing QAM modulator and DVB set top boxes.

The IBC Exhibition is one of the largest broadcast events each year and takes place at the Amsterdam RAI on Sept. 13-17, 2002.
