1. Overview
DMM-1701IM is a high performance twin IP to analog trans-modulator, it supports
MPEG-2\H.264 digital signal decoding with HD\SD definition. With 2 independent IP
interface, it can receive 2 IP multicast/unicast, and trans-modulate 2 programs by built-in
modulators, then outputs a combined signal via RF output port.
With its full compliance to analog standards including PAL, NTCS and SECAM,
DMM-1701IM is a better deployment for digital to analog system.
