COL5881A FTA QPSK Demodulator
Summary
COL5881A FTA QPSK Demodulator is an enhanced TS re-multiplexer for digital TV broadcasting head-end system. The multiplexer has all the functions of normal TS multiplexer, including programs multiplexing, PSI/SI editing, PID re-mapping, service filtering etc. Also the multiplexer can insert EPG (Electronic Program Guide), CA (Conditional Access) and data casting information into each output stream. Different from normal multiplexer, this multiplexer has 2 ASI inputs, 6 tuner inputs (DVB/C/S/S2/T) optional, two separate ASI output ports and one DATA port for two separate megabit IP outputs. In other words, It can multiplex the RF signals into the output ports via the 6 tuners, also it can multiplex up to 2 channels ASI input MPTS into the output transport stream (MPTS). Therein, the bit rate of output stream can be up to 216Mbps. For the application area, this device is especially applicable to the FTA (Free to Air) system multiplexing.
