SKD201X Encoding & Modulation Modulator is an extremely compact and simple digital modulator. Case thickness is only 3CM, with standard feature of commercial modulator. HD signal can be modulated into various formats such as ATSC/DVB-C (J.83A/J.83B)/DVB-T/ISDB-T/DTMB after being encoded by MPEG2 standard. HDMI loop output, can be widely used in home entertainment, security monitoring, Hotel signs and Shopping mall advertising and other places.
