Professional DVB multi-standard receiver and trans-modulator


Item: 3901


The IDLV-4100PM is part of Inverto’s flagship professional trans-modulator series. He offers much more than QAM or COFDM modulation and provides powerful and flexible DVB PSI/SI processing features. The wide variety of interfaces includes support for DVB-S2/S, DVB-T, DVB-C, ASI, TSoIP and DS3 reception. This makes the IDLV-4100PM suitable for a wide range of deployment scenarios of digital TV distribution system where QAM or COFDM modulation is required. The IDLV-4100PM has two CI slots for descrambling. Multi-program descrambling can be achieved when using a professional CAM module. The IDLV-4100PM incorporates a re-multiplexer which can multiplex streams from the Tuner, IP, and ASI inputs and outputs a customized DVB-compliant QAM or COFDM modulated TS. Furthermore, the IDLV-4100PM offers a unique redundancy mode where the Tuner, ASI Input and IP Input can be configured in order to back up each other. This unique functionality maintains the availability of the distribution system even when one or two input signals malfunction or simply shut down.


The IDLV-4100PM integrates with SNMP-based management systems, which can be managed and controlled over a built-in HTTP-based web interface, PC software management tool (HDMS) or over its front panel interface.
