DB7016 is an IP Multiplexer with QAM which can receive multiple MPEG-2 TS in form of IP data, and then multiplex, scramble, and insert local information to the TS, finally output RF signals after QAM modulation. The input signal could be the IP output from encoder/receiver/multiplexer/VOD server, and it can be used in DTV core-to-edge TS processing and modulation.

Main Features:

• IP data input: GbE SFP port/RJ45 port
• Support unicast and multicast (IGMP2.0/ 3.0)
• Complete solution for multi-channel re-multiplexing, scrambling and QAM modulation
• Input stream auto-detection and user configuration auto-saving
• Support up to 4 simul-crypt CAS and DVB-CSA scrambling
• Support tiered scrambling of all programs under VOD mode
• Support SI/PSI auto-generation or manual uploading during re-multiplexing
• Support PID filtering, mapping, and pass-through
• PCR auto-correction
• Simultaneous processing of up to 250 input TS, 24/32 output TS and 2000 DTV programs under broadcast mode
• Simultaneous processing of up to 510 input TS, 24/32 multiplexed output TS under VOD mode
• Support ITU-T J.83 Annex A/B/C modulation, output frequency range: 30 MHz~860 MHz
• Dual RF output ports with up to 24/32 QAM frequencies output (4-adjecent-frequency)
• Outstanding out-of-band rejection, in-band EPL balance capability
• Support gain fine-tuning
• Support Web/SNMP-based management
• Support device configuration import/export
• Support online remote update

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.
