DAP - Digital to Analog Processor
The Digital to Analog Processor (DAP) is a complete single channel
solution for delivering digital television programming over existing
analog networks. The DAP is housed in a one rack high unit and
features a backlit 2 x 16 character LCD screen and push button
navigation switches to allow interaction with the simple to follow
user menu functions for programming. Input and output tuning
is easily accomplished with either the front panel menu interface
or via the optional Remote Network Card; only one RNC per
headend is needed for complete configuration and control of all
DAPs that are daisy chained in the headend. The DAP supports
standard EIA CATV, IRC, HRC and Broadcast channel plans in the
54—864 frequency range. All channel frequency information,
with appropriate FCC offsets, is pre-programmed and tuned
electronically via microprocessor. The unit is also equipped with the
Emergency Alert System (EAS) feature which can also be used as
an alternate IF input.
