Transmodulator EQ80: Key Features

The Transmodulator EQ80 is an integrated device that can encode, multiplex, and modulate 8 CVBS video signals and 1 ASI input into DVB-C/T RF outputs between 30-950MHz. It supports MPEG2 and optional H.264 video encoding at bitrates from 1-15Mbps, as well as MPEG1, AAC, and AC3 audio encoding. The EQ80 provides MPTS or 8 SPTS IP streaming outputs and can achieve low latency operation. It has a 1U rackmount case and integrates LCD control, web management, and software upgrade capabilities.
