Multiplexing Hybrid QAM Modulator 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. The MEQ1000 has bays for up to two input modules. The video content from both modules enters the main chassis where it is MPEG program filtered, multiplexed, and groomed. Any number of program streams may be sent to the QAM modulator or be exported via ASI Output.
