Overview
VT-4201 4IN1 SD Encoder Modulator DVB-T supports 4*CVBS and 4 pairs of unbalanced audio and 1*RF input and 1*RF (DVB-T) output. After coded and modulated, the input signal can be directly output or mixed output with original TV signal. It suits 1U rack and can be configured by front panel LCD and NMS (network management software). Its high-integrated and cost-effective design makes it widely used in varieties of digital distribution systems such as cable TV digital head-end, satellite digital TV broadcasting and terrestrial digital TV, etc.
