ENCODER & 8VSB MODULATOR

ENCODER & 8VSB MODULATOR.  
               
                                                                        
 
APPLICATION
   • This product is an all-in-one equipment embedded with a MPEG-2 HD encoder and a 8VSB modulator.
     When there is input of signals including HD-SDI, HDMI and component(1080i), HD-SDI embedded audio,
     HDMI embedded audio, stereo analog audio and AES/EBU, the product compresses the signals into MPEG-2 HD,
     a signal in high definition and modulates into 8VSB, a domestic digital terrestrial broadcasting standard(ATSC),
     making RF signals from 54 MHz to 860 MHz. This product is the best for self-broadcasting as well as in-house broadcasts,
     and it is the optimal solution for retransmitting broadcasts in high definition.
