The Drake Digital MEQ1000 is the industry’s first commercial-grade, multiplexing Hybrid QAM modulator. Ideal for applications where a single QAM output is required from each Hybrid QAM chassis, the MEQ1000 features a variety of plug-in input modules including an ATSC/QAM input tuner, an ASI input, an IP input (future release), and analog NTSC inputs, bringing an unprecedented level of flexibility to cable operators
- ASI input clock: 270 MHz
- ASI input data rate: Maximum of 80 Mbps
- ASI output rate: Identical to the ASI input stream
Drake Digital DTD1000 Module and ASI II Module
The DTD1000 input module tunes any 8VSB or QAM channel between 54 and
1002 MHz, making it ideal for digital channel processing applications
where a single digital video signal is received, error-corrected,
clocked (at a user determined fixed rate) and re-modulated on the same
or another RF channel.
The DTD1000 may be used to convert one off-air ATSC 8VSB signal to a
QAM output with rate adjustment or, when used in the processor mode with
only one input, the MEQ1000 can process ATSC or CATV QAM MPEG-2 inputs.
ASII ASI Input Module
The ASII module is for use in the MEQ1000. One module provides one
DVB-ASI SPTS or MPTS input for the MEQ1000. One or two ASII modules may
be used in a MEQ1000.
Using the ASII module, programs may be input to the MEQ1000 where
they will be program filtered, retimed, and multiplexed with programs
from the other input module.
The ASII module can accept data rates up to 80 Mbps. Possible sources
are satellite IRDs, output from a fiber link, encoders, terrestrial
demodulators, video servers and other related equipment.
The ASII also provides an ASI output which provides a looped out copy
of the ASI stream coming into the ASI input port of the same ASII
