Gennum develops new A/V interface

Aviia delivers HD over coax solution for immediate integration into cameras, DVRs


BURLINGTON, Ontario, February 25, 2009 – Enabling equipment manufacturers to leverage existing coaxial cable infrastructures, Gennum Corporation (TSX:GND) has developed a new audio video (A/V) interface for professional and industrial applications, such as advanced video security and surveillance systems. Aviia (Advanced Video Interface for Industrial Applications) is a robust interface for high definition (HD) video over coaxial cable lengths up to 100 meters. This allows users to easily upgrade their existing analog over coaxial systems, the dominant technology implemented in surveillance systems today, to full bandwidth HD video, up to 1080 lines progressive. Gennum’s Aviia solutions will be demonstrated next week at the Security Show 2009 in Tokyo.

The new interface expands Gennum’s A/V technology, currently the proven standard in the professional broadcast and consumer connectivity industries, into new markets including video surveillance, machine vision, medical, digital signage, passenger infotainment, industrial imaging and video conferencing.

Today, most closed circuit television (CCTV) systems used in video surveillance applications use coaxial cable, which, until now, has been unable to support the high resolutions of HD. As a result, users have either maintained their analog systems with lower video resolutions or have resorted to costly infrastructure changes to Ethernet-based networks. By using Cat-5 cable to bring HD video into their environments, the network systems compromise the video immediately by compressing video in the camera for transmission over the network. In addition to incurring the obvious infrastructure costs, there are significant security concerns such as hacking, bandwidth availability and down-time typically experienced with a network-based approach, which has made an HD-over-coax option desirable but, to date, unattainable.

”With millions of miles of coaxial cables installed, many users want to upgrade their surveillance video applications to HD video, but are hindered by the expense and disruption associated with an infrastructure change,” said Martin Rofheart, Senior Vice President and GM of Analog and Mixed-signal Products at Gennum. “By leveraging the technology we have developed for many of the world’s leading broadcast equipment manufacturers, we are able to bring a cost-effective, high quality solution to a wide range of industrial applications. Moreover, camera, DVR and monitor manufacturers can now develop low cost, high-performance HD solutions, enabling customers to experience full bandwidth HD over their existing coaxial cables.”

Solving the HD over Coax Challenge

Applying its advanced signal integrity expertise, Gennum developed the Aviia interface and accompanying suite of products that can be easily integrated into the architecture of digital video equipment, such as cameras, monitors and digital video recorders (DVRs). Featuring transmit and receive functions to enable bi-directional transmission, the Aviia solutions create a new I/O that enables equipment manufacturers to provide their customers with a cost-effective, high quality HD product capable of transmitting across coaxial cables. Moreover, the use of this interface ensures that the HD stream from source (camera) to destination (DVR, monitor, etc.) is transmitted at full bandwidth with no video compression needed.
