Description

1.1 Outline

STM-2400 is a cost effective integrated 4 in 1 QAM modulator supporting multiplexing and scrambling. This device supports maximum 8 DVB-S2 tuners input, after 4 multiplexer and 4 scrambler processes, then gives 4 carriers output (4 adjacent frequency by 1 RF port) and gigabit IP output. The device is characterized with high integrated level, high performance and low cost. This is very adapting to newly generation CATV broadcasting system.
