S-A Continuum DVP eXtra Dense QAM Array

The Scientific-Atlanta Continuum DVP eXtra Dense QAM Array (XDQA) is specifically targeted to cable operators looking for a high-end, cost and space-efficient solution for their video-on-demand (VOD/SVOD) rollout. It is a self-contained device combining GbE Interfacing, Routing, Multiplexing, QAM modulation and up-conversion functions. Scientific-Atlanta’s DirectRF technology ensures QAM specifications meeting or exceeding the DOCSIS standard (1). Superior RF performance is especially critical when migrating to IP backbones for distributing broadcast services. The Continuum DVP XDQA allows one QAM product for narrowcast and broadcast services. The Continuum DVP eXtra Dense QAM array is an ideal bridge between flexible IP and Gigabit Ethernet based backbone networks and existing QAM set-top boxes. Its hot swappable modular design allows for scalability by adding QAM cards only when more capacity is needed. QAM cards are configured automatically when inserted, which reduces set-up and maintenance time to a minimum. The Continuum DVP eXtra Dense QAM Array can be configured via an embedded user interface that can be accessed with a standard Web browser. There is a dedicated Ethernet port for system management and control. An open communication protocol (SNMP) is provided to interface with the VOD management system.
