The Blonder Tongue AQT Transcoder is a modular unit that receives either an 8VSB (Off-air Digital) or QAM (CATV Digital) signal, and transcodes it to any CATV QAM channel. The transcoding enables televisions with QAM digital tuners to seamlessly view the 8VSB Off-air digital signals on cable television frequency assignments without having to change the television tuner input from ‘CATV’ mode to ‘Off-Air’ mode. The input digital signal is stripped of it’s original digital modulation (8VSB or QAM), leaving just the basic data stream. The AQT then creates a new, clean QAM carrier and reinserts the original data stream on to this new QAM carrier. If the original channel was encrypted, it will remain encrypted, if the original channel was in the clear, it will remain in the clear. The only modification to the original data stream that is performed is changing the data rate when converting an 8VSB signal to a QAM signal. This rate change is done via Null Packet processing and does not affect the encryption in any way. The regeneration of a new, clean QAM signal is also useful for digital ‘cherry-picking’ from an existing digital channel line-up, or ‘regenerating’ a channel for optimal Modulation Error Ratio (MER) performance.

Introduction

Markets

Digital channel processing applications including:

• ATSC/8VSB Signal to QAM – Today’s TV manufacturers are moving towards only allowing QAM carriers to be tuned in the “CATV” mode, and 8VSB carriers in the “Off-air” or “Broadcast” mode, where the tuners used to tune either 8VSB or QAM when set in “CATV” mode. Given this recent trend Blonder Tongue created the solution to convert one off-air ATSC/8VSB digital off-air signal to a QAM digital CATV signal that can be tuned by the current generation of digital tuners. This eliminates the problem of having to reprogram the television every time the customer wants to switch between digital CATV and digital off-air channels.

• Digital ‘Cherry Picking’ – The AQT Family of products can be used to ‘Cherry Pick’ selected digital channels from an existing CATV QAM digital lineup and process it for redistribution. If the original CATV QAM channel was encrypted, it will remain encrypted, requiring an authorized set-top for viewing. If the original CATV QAM channel was in the clear, it will remain in the clear, and can be viewed on any television with a QAM digital tuner set to “CATV” mode. The AQT can also be used to ‘Cherry Pick’ and insert selected CATV QAM carriers in to a bandwidth limited private CATV network. If a large facility only has a 450 MHz distribution network, and the MSO’s digital offering starts at 650 MHz, there is no room for the digital tier without a costly network upgrade. The AQT can received the desired high frequency QAM channels and transcode them to available channels within the existing 450 MHz network, delivering the desired CATV QAM channels, while preventing a costly network upgrade.

• QAM Regeneration – As RF signals travel through distribution networks, the signals become degraded for a variety of reasons, CATV QAM digital channels are not exempt from this degradation. The AQT Family of products can be used at a remote hub location to restore a high quality CATV QAM digital carrier. The input CATV QAM digital signal is stripped of it’s original digital modulation (QAM), leaving just the basic data stream. The AQT then creates a new, clean QAM carrier and reinserts the original data stream on to this new QAM carrier. This ‘regeneration’ process creates a new, clean QAM channel with an optimal Modulation Error Ratio (MER) performance for continued distribution to subscribers.distribution to subscribers.

The AQT (ATSC/QAM Transcoder Series) from Blonder Tongue features a state-of-the-art approach and offers 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 AQT Series transcoder modules are compatible with off air 8VSB signals to transcode to QAM signals. It is also well suited for regenerating or changing the channel of a QAM signal.

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 AQT 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 AQT power & control module. This is easily added at any time for an operator by interfacing to the optional standby power supply unit. In addition, the optional AQT Remote Configuration 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.
