An Emergency Alert System Analog/Digital Encoder/Decoder Platform
The One-Net DASDEC II are State-of-the-Art Emergency Alert Systems (EAS) Analog/
Digital Encoder/Decoder platforms. First introduced in 2005, this system is being
deployed around the United States in a wide variety of Cable, Broadcast, IPTV, and
Emergency Operation facilities. The EAS device is built with the latest digital PC
computer technology. The encoding/decoding technology is software based, and is
built upon the Linux OS. The core hardware is a standard PC motherboard and digital
audio sound cards. The EAS device is easy to upgrade, not requiring custom ROMS. The
EAS device also exploits the benefits of modern network technology. It is fully operable
over a LAN using secure network protocols. In addition, it supports existing methods
of device control using a serial port. This platform is representative of the continuing
advance of PC hardware into technological areas that only a few years ago required
custom hardware.
