AR-3001Q IP QAM MODULATOR
Preview
AR-3001Q IP QAM modulator is to convert the input 128×IP signal into digital DVB-C/DVB-T/DTMB/ISDB-T RF signal. It Supports multiple modulation methods DVB-C/DVB-T/DTMB/ISDB-T, without hardware replacement. Its cost effective design makes the device widely used in digital TV and broadcasting system etc.
DTMB modulation: Support BCH/LDPC encoding, interleaving and baseband processing. RF output with frequency of 36M-900M. According to standard (GB20600-2006)
DVB-C modulation: RS encoding, Convolution interleaving and QAM modulation. RF output with frequency 36-900M. According to DVB-C(ETS300429) standard.
DVB-T modulation: RS encoding, outer convolution, inner convolution and QAM modulation. Support 2K/8K model. RF output with frequency 36-900M. According to DVB-T(ETS300744) standard.
