Gennum develops new A/V interface

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


According to IMS Research, the worldwide video surveillance market is forecast to be worth $9.5 billion in 2009, growing to an estimated $14.3 billion in 2012.

“The global market for video surveillance equipment is expected to grow well beyond 2012, with the highest growth coming from China, Latin America and Eastern Europe,” said Alastair Hayfield, market analyst at IMS. “The megapixel camera market is a rapidly growing segment of the total camera market with high double-digit revenue growth forecast beyond 2012. The improved image resolution that megapixel and HD surveillance brings is appealing to a wide range of verticals where better object detection or person recognition is a much sought after commodity.”

"Physical security demands video resolutions beyond D1 without incurring significant increases in system price and without compromising the evidentiary norms built up around DVRs," said Todd Rockoff, Vice President for Global Sales of the ODM Business Unit of EverFocus, a Taiwan-based manufacturer of physical security equipment. "We see tremendous latent demand for high-definition CCTV that plugs in directly to the large installed base of coaxial cable. HDCCTV promises to deliver high-resolution far more conveniently and inexpensively than IP Cameras. EverFocus expects hybrid DVRs, accepting both SD and uncompressed HD TV signals over coax enabled by Aviia, to become a high-growth product category."

Suite of A/V Products Brings Low-Cost Alternative to Ethernet, Cat-5 Implementations

Gennum applied its advanced serializer/deserializer technology to achieve an end-to-end upgrade path for HD video transmission over 100 meters plus of coaxial cable. Currently, Gennum is delivering 100 meter coaxial solutions with its ActiveConnect product, which is being used in custom home theater applications to provide a low cost, long reach HDMI interface solution.

Gennum’s new Aviia suite of products leverages this expertise to deliver an innovative high-bandwidth, all-digital, long-reach A/V interface for professional and industrial applications. Seamlessly integrating into existing digital architectures, the products provide high-definition video; digital audio; bi-directional control such as pan-tilt-zoom and camera configuration, over a single-wire, delivering a robust and cost-effective interface. Additionally, the Aviia suite of solutions provides for power over the coaxial cable itself, operating at 3 to 25 volts DC, up to 25 watts.

Specifically, Gennum’s Aviia suite includes the GV7500/01 Aviia SD transmitter/receiver; the GV7600/05 Aviia transmitter/receiver (supports both SD & HD video) and the GV7601 Aviia receiver (SD and HD support with integrated cable equalizer technology).

With support for 720p, 1080i and 1080p video formats, as well as 525i and 625i (D1) video, Gennum’s new Aviia solutions enable HD video to be transmitted without the use of in-camera compression, providing an improved operator experience and higher quality evidence, in the case of surveillance systems. Providing a single 75-ohm coaxial bi-directional multi-media interface, the new suite of products can provide link bandwidth up to 3 Gb/s downstream and can support up to 8 channels of linear PCM audio at 48 kHz sampling. Additionally, Aviia solutions provide support for 6 Mb/s auxiliary data channel, for applications such as up-the-cable control, “intercom” audio back channel, and remote status and monitoring.
