Product Details

Place of Origin	Zhejiang, China		Brand Name	Dibsys
Model Number	EMI3084

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.

Feature

1.Up to eight channels of MPEG-2 SD video and MPEG-1 Layer 2 audio encoding

2.High picture quality in ultra low bit rate to reduce network overheads or costs

3.Support encoding rate range from 1Mbps to 7Mbps

4.Support input channel coding multiplexing simultaneously to two QAM Channels output

5.Support VBR/CBR video encoding

6.Transport stream multiplexing, remultiplexing sand pass through via ASI,DVB-C RF input

7.Support PID filtering, pass-through, PCR auto-correction

8.PAT, PMT and SDT insertion

9.Up to Dual QAM adjacent-channel outputs

10.Wide range of modulation output bitrate from 15.5Mbps to 51.6Mbps per QAM channel

11.QAM constellation: 16/32/64/128/256QAM

12.ITU-T J.83 Annex A/B/C compliant, 6MHz or 8MHz bandwidth

13.Self-adaptive filter circuit design ensures outstanding out-of-band rejection

14.Web browser GUI and SNMP management for local and remote management

15.Local and remote firmware upgrades

16.Low power consumptions, Tilted more than 45 degrees of intelligence to turn it off
