INTRODUCTIONS
RMT9021 IP to DVB-T modulator is one of our modulators, which is mature and in good performance. This device is able to be input with 2*IP streams(MPTS or SPTS), in multicast or unicast mode, UDP protocol, and modulate them out in two adjacent DVB-T carriers. It is also easy in operation by LCD keypad on front panel, as well as web network management system. It is a professional broadcasting device for operators, project providers and is widely used in DVB head-end systems.
