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 a 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. The MQAM can be used as a STAND ALONE unit orunder control of the Digital Network Control System (DNCS), the MQAM can be located in either the headend or hub.
