AQT - ATSC to QAM Transcoder
The Blonder Tongue ATSC to QAM Transcoder is a modular unit
that allows the reception of a modulated 8VSB or QAM signal
input and transcodes it to a QAM modulated output signal. The
unit is designed to tune to an off-air 8VSB or QAM digital signal
and convert it to a digital QAM signal to permit interface with
digital TV displays with QAM tuners.
Applications
Digital channel processing including:
• Changing the incoming QAM channel to a different RF QAM channel
• Complete regeneration of a QAM input for optimal MER performance
• Convert one off-air ATSC 8VSB signal to a QAM output
Features
• 8VSB, 16VSB, Annex A QAM 16, 32, 64, 128 & 256 and Annex
B QAM 64 & 256 Modulated RF Input Transport Streams
