All-In-One MPEG-2 SD Encoder-QAM Transmodulator

Model No: GN-8318Q

1: Support encoding and modulating

2: AV input and Output with IP / ASI after modution

3: Support AAC


Product Overview


GM-8318Q is a new generation, 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 consumption for digital television distribution

.

The GM-8318Q features versatile functions, high density and superior performance, provides up to eight channels of MPEG-2 standard definition(SD) encoding, QAM RF demodulation, ASI-based transport stream input, transport 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 which can be processed into two transport streams and finally distributed to cable network after QAM modulation.


To make this as comprehensive as possible, Web browser and SNMP management are also available for local and remote monitoring and control, this can significantly reduce management time and save operating expense.
