Product Overview:
GM-8358Q is a new generation, highly integrated SD encoder and QAM
transmodulator, combining MPEG-2/MPEG-4 AVC 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-8358Q features versatile functions, high density and
superior performance, provides up to eight channels of MPEG-2/
MPEG-4 AVC standard definition(SD) encoding, QAM RF demodulation,
ASI-based transport stream input, transport stream
multiplexing/re-multiplexing/pass-through, PSI/SI processing,
DVB-CSA scrambling, 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.
