HD Encodulator – Professional HD Encoder and Modulator (ATSC/DVB-T/DVB-C/DTMB)

Description

The HD Encodulator is a professional HD MPEG-2/H264 Encoder with a built in modulator that can support numerous terrestrial DVB modulation standards.
These include ATSC (8VSB), DVB-T, DVB-C and DTMB.  The device can also be used as a standalone encoder through the built in IP and ASI outputs.
