DR-2098HIA Mobile Digital Receiver
DR-2098HIA is a professional mobile digital receiver to convert the
input tuner signals to crystal clear digital or analog video in
various formats available at CVBS, YPbPr, HDMI, and HD-SDI.
It is designed to support the industry standard 576i/480i,
576p/480p, 720p and 1080i decoding.
It is also equipped with 1 ASI input, 2 ASI output ports and a data
port for both input and output to make it possible to process more
programs.
Additionally, the implemented web server allows the configuration
of the DR-2098HIA with a standard web browser. Basic configuration
can also be done locally with the LCD display and navigation
buttons. The LCD monitor can, at the same time, realize the
real-time observation about broadcasting status.
