DB-7048 is a new generation of DBC IPQAM device capable of processing up to 48 output channels. It takes multiple UDP format MPEG-2 transport streams and applies multiplexing, scrambling, and local information insertion (such as EPG, NIT, etc.) on them, then finally outputs RF signals after QAM modulations. DB-7048 supports up to 3 daughter boards, with each of them supporting 16 output QAM channels and equipped with 2 optical/electrical slots which can be used for either RJ-45 or SFP ports. The daughter board can be physically installed and uninstalled anytime when the power is off which provides users with flexibility for using. DB-7048 supports functions of pass-through, multiplexing, scrambling, and modulation. It also supports module authorization management system, by which the number of CAS simul-crypt channels can be added from 0 to 4 by the authorization program file. DB-7048 is equipped with web-based management and SNMP, which makes it possible for remote online control and monitoring. DB-7048 can be applied to cable DTV head-ends, sub head-ends, or broadcasting centers. With its powerful processing capability, one unit of this device can easily meet various customers’ satisfactions.
