The QAM Transcoder Series from Blonder Tongue features a state-of-the-art approach and offers the ultimate combination of a fantastic price per channel while still maintaining top notch performance and functionality. It incorporates a scalable modular design that allows from one to eight transcoder module units as well as a single combination power supply & control module to be added, removed or swapped at any time in the 3 rack high chassis. The QT Series transcoder modules are compatible with DVB satellite signals (ITU-T J.83 Annex A) from EchoStar's DISH Network™ & Bell Canada's ExpressVu as well as DigiCipher® II satellite signals (ITU-T J.83 Annex B) from Comcast Media Center's and Shaw Broadcast Service's HITS QT and QT Plus programs. Several module types are available to permit the reception of QPSK based signals for SD (standard definition) and 8PSK based signals for HD (high definition) as well as Null Packet processing required for various transponders. The modules are housed in a custom designed chassis intended to accommodate from one to eight different modules as well as specially designed chassis mountable splitters and combiners to make wiring simple and painless. Control of the transcoder units is easily accomplished with a common power supply & control unit via operator selection from the front panel push button controls and back-lit LCD panel. This module interfaces to any of the QAM transcoder modules through a simple 12-pin connector and cable. The control module's brain is a flash upgradeable microprocessor to ensure support for any future development. Support for redundant back-up or ‘standby' power is also built into every QT power & control module. This is easily added at any time for an operator by interfacing to the optional standby power supply unit. Plus, the optional Headend Web Server provides the ability to remotely control and monitor any of the transcoder modules over the Internet – this makes turning off a problem unit and reprogramming a live spare a quick fix preventing an immediate truck roll.
