Product Description

Broadcast 8 A/V Digital Video Modulator

EMI3084 is a new generation and highly integrated SD encoder and QAM transmodulator combining MPEG-2 SD encoding, QAM RF reception, transport stream processing and QAM modulation in a 1RU chassis. It’s ideal for broadcasters, cable network operators and media providers looking to reduce equipment costs and lower total power consumptions for both digital television service contribution and distrubution.

The EMI3084 features versatile functions, high density and superior performance, provides up to eight channels of MEPG-2 standard definition(SD) encoding, QAM RF demodulation, ASI-based transport stream input, trasport stream multiplexing/re-multiplexing/pass-through, PSI/SI processing, two QAM modulation outputs. All of these feeds incoming from local analog PAL/NTSC video&Audio media sources, local ASI transport streams and remote QAM RF signals could be processing into two desirable transport streams and finally distribute to cable network after QAM modulation.

As a comprehensive contribution and distribution equipment, the Web browser and SNMP management are also be introduced for local and remote monitoring and control, this can significantly reduce management time and save operating expense.
