Description 
The D9477 MQAM (multi-
QAM) Modulator provides an 
ideal solution for mass 
deployment of video-on-
demand (VOD) services. It 
contains all of the core 
functionality of our single unit 
QAM modulator, plus several 
additional capabilities for 
deploying VOD quickly and 
reliably.  
 
By multiplexing MPEG-2 video content from two ASI inputs to any of four independent RF outputs, the MQAM 
provides savings both in rack space and cost per video stream over our single-unit QAM. These ASI inputs also 
allow direct connection to a video server for VOD applications. Under control of the Digital Network Control 
System (DNCS), the MQAM can be located in either the headend or hub. 
 
Features 
•  Four QAM ITU-A, ITU-B 
or ITU-C outputs in two 
rack units (2RU) where 
one unit equals 1RU plus spacer 
– All core functionality of a single Conditional Access (CA) QAM unit 
– Less rack space; 2RU MQAMs replace 8RU CA QAMs including spacers 
– 91 MHz to 867 MHz output center frequency range 
•  Dual, full ASI inputs (216 Mbps each); able to multiplex content to any of four RF outputs 
•  Includes DVB common scrambling, PowerKEY
®
 DES, and Harmony capability 
•  DNCS system management 
 
Benefits 
•  Higher rack density saves space – 2RU MQAMs vs. 8RU CA QAMs  
•  Lower cost per video stream than with a single unit QAM 
•  Multiple core encryption options can be enabled after deployment 
•  Provisioning and monitoring by the DNCS – MQAMs deploy in the headend or hubs 
•  Uses second ASI input for multiplexing a second data source or as a redundant input
