Overview
DIGICAST Encoder mdolator series that transforms a digital video and audio (HDMI) signal/IP/ASI into a modulated FullHD (MPEG-4/H.264) signal into a DVB-T/C/ATSC/ISDB/DTMB channel. The input digital signal comes from an external SD/HD source: satellite receiver, DVR/NVR, DVD, CCTV, etc.
The channel generated by the HDMI source can be mixed with the DTT signal and then distributed over a single coaxial cable. Its content can thus be displayed on all the receiving devices of the system.it is the idea solution for inserting more programs from loca/internet to existing coaxial sytem, widely used in hotel/hospital/shopping mall …or CATV operators system.
