Gennum
announced today a two chip transmitter/receive chip-set for
delivering high definition (HD) video over coaxial cable lengths up
to and beyond 100 metres. The chip-set, called Aviia GV7601
(receiver) and GV7600 (transmitter), allows users to upgrade
existing analogue video over coax applications to full HD
video.
Both the GV7600 and GV7601 are being designed into first
generation High Definition closed circuit television (HDcctv 1.0)
cameras and DVRs today, allowing closed circuit television system
customers that currently use coaxial cable to support HD.
By using Gennum's HD Transmitter/Receiver solution customers can
avoid the expense and disruption of a full system infrastructure
upgrade while gaining all the benefits of full bandwidth HD over
existing coax cables.
"Aviia (Advanced Video Interface for Industrial Applications)
brings the image quality benefits of HD to a variety of industrial
applications like security and surveillance where leveraging
installed cabling infrastructure enables economical and quick
upgrades," said Vijay Sharma, director of product marketing,
Gennum
Aviia is a real-time A/V interface ideal for low latency, frame
rate critical applications where high image quality and reliability
are required, and provides bi-directional communications and
Power-over-Coax, allowing both control and powering of remote
devices, such as cameras.
The bi-directional communications channel can be used to send
Pan Tilt Zoom (PTZ) configuration and status data. The Aviia
interface can also be configured to provide bi-directional audio
for intercom applications.
The GV7601 is an Aviia HD Receiver with integrated cable
equalization technology. When used in conjunction with the GV7600
Aviia HD Transmitter, it provides a complete two-chip long reach
(150 metres) A/V interface over a single coax.
The GV7601 supports both Standard Definition (SD) & High
Definition (HD) video formats up to 1080p at 50/60 Hz (Full HD) and
features an integrated audio de-embedder supporting extraction of
up to 8 channels of digital audio.
Long reach HD cable performance includes up to 230m using high
quality 75-ohm coaxial cable (Belden 1694A or equivalent) and up to
160m typical using RG59 or equivalent (commonly used in analogue
video CCTV installations).
The GV7601 offers low power operation, typically 570mW at HD and
comes in a small 100-BGA package (11mm x 11mm). The GV7601 is ideal
for a wide range of industrial A/V markets and applications,
including: Video Surveillance, Videoconferencing, Machine Vision,
Digital Signage & Large Venue Displays, Industrial A/V and
Medical Imaging.
The GV7601 and GV7600 are in full production with a reference
design kit for both parts available now.
