ATSC/QAM Demodulator - HE-12 & HE-4 Series

SKU: 6273 Category: Tag:

Product Overview

The MDDM-860 is a digital demodulator and decoder that receives one input in ATSC 8VSB (digital off-air) or “clear” QAM (digital cable) format and delivers one NTSC composite analog video and stereo audio output.

The unit allows delivery of a digital off-air program to viewers with an analog TV set. It also enables operators to cherry-pick channels from a clear QAM cable lineup.

Headends processing analog broadcasts using Blonder Tongue’s MIDM demodulators and MICM modulators can be upgraded seamlessly to process digital broadcasts by simply replacing the MIDM with a MDDM. The MDDM-860 is part of the HE-12 and HE-4 Series.
