Product Description

Broadcast Edge QAM Modulator

The DIBSYS’s IPQ6250 is a new generation of modular & high density Edge QAM modulator combining TS-over-UDP/RTP reception, transport stream re-multiplexing, scrambling,PSI/SI processing and 16/32/64/128/256QAM modulation in a 1U rackmount unit. It supports up to 48 QAM channels by using three external pluggable 16 QAM modules, each of QAM modules supporting up to two Gigabit copper interfaces. Moreover, the Modulator supports 1+1 redundant & hot-swappable power supplies for high reliability and stability of system. Its pay-as-you-grow modular design, flexible configurations and licensing mechanism are making the Modulator unparalleled scalability, reliability and system performance to cable operators. The adopts Web browser and SNMP management with remote monitoring and control that can greatly reduce management time and operating expenses (OPEX) of operators.

The IPQ6250, cable operators can be ensured that they will have a scalable, reliable, high performance video stream services for years into the future. It can be applied to cable DTV head-ends, sub head-ends and VOD networks.
