7. Functional description
The module receives a data stream via Gigabit Ethernet. It can receive up to eight transport streams from the included IP encapsulated
transport streams. The eight transport streams are further processed in eight H.264/ AVC & MPEG2 decoders. A high-performance
FPGA does the analogue TV modulation and the freely adjustable up-conversion into the cable network range (45 ... 862 MHz).
The eightfold modulator is adjacent channel compatible. A high-speed digital
→
analogue converter (DAC) is responsible for the
excellence output signal. After amplification and sum level adjustment the cable signal is coupled through a switchable directional
coupler to the output jacks.
