AQD Family of Products

 Receives & Demodulates 8VSB, QAM 64 & QAM 256 (Annex B) Input Streams • Modular & Compact Units Permit High Density — 8 Modules in 3 RU • Outputs 480i NTSC Composite Video

Demodulator or AQD is a high performance modular digital receiver that allows for the reception and demodulation of an 8VSB (Off-air SD/HD digital TV Signal) or QAM (Digital CATV) Annex B signal into a baseband NTSC video and audio output.

This permits the delivery of digital television signals in a analog format directly to a television or to interface easily with existing analog modulators on CATV networks.

Most operators and consumers are aware of the federally mandated US government deadline for the transition from analog to digital broadcasts. This deadline has been set for February 17, 2009 by Congress. This means that all off-air analog signals will be terminated and replaced by standard and/or high defi nition digital signals. A similar mandate has also been set for the Instructional Television Fixed Service (ITFS) or newly renamed Educational Broadband Service (EBS) providers. This creates a dilemma for the millions of perfectly good working analog television sets deployed in the market, especially in educational and institutional environments. The AQD Series from Blonder Tongue solves this dilemma. Designed to bridge the digital transition gap, the AQD permits the receipt and delivery of digital originated TV signals in analog format so that the need and requirement to purchase expensive new digital/HD televisions or converter boxes for each viewing location is eliminated. The AQD provides a infrastructure based solution that allows for the replacement of sets in a more economical reasonable manner.

• Any large installed base of analog television viewing locations, easing the cost to upgrade to digital capable televisions immediately

• Educational & Institutional Facilities — Schools, Universities, Hospitals, Prisons, Nursing Homes, Military Bases, etc.

• EBS Broadcast environments to permit simultaneous analog & digital transmission

• Any location that requires digital 8VSB or QAM reception converted to analog

• Television Studios for conversion of digital signals to analog format, great to monitor broadcasts in analog & for locations where digital upgrade is not permitted

• Any location that has a need to simulcast an analog and digital television signal

• Digital ‘Cherry Picking’ of un-encrypted QAM channels

• Locations that can not budget or afford to replace and upgrade all of the viewing locations to digital capable

AQT Family of Products

The Blonder Tongue ATSC to QAM Transcoder (AQT) 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 ‘cherrypicking’ from an existing digital channel line-up, or ‘regenerating’ a channel for optimal Modulation Error Ratio (MER) performance. The Blonder Tongue ATSC to QAM Transcoder (AQT) is a modular unit that receives either an 8VSB (Off-air Digital) or QAM (CATV Digital)

Transcode Digital 8VSB (Digital Off-Air) or Regenerate QAM (CATV Digital) Signals to QAM on Any Channel with the AQT.

Digital channel processing applications including:

• ATSC/8VSB Signal Transcoding to QAM – It is common for digital televisions to only lock to QAM type signals when set or tuned to the “CATV” mode. This creates difficulties for operators transmitting standard ATSC (“digital off-air” or “broadcast”) 8VSB signals. The Blonder Tongue AQT solves this problem by converting an entire 8VSB (ATSC) off-air digital channel to a QAM digital signal. This new QAM channel can be transmitted by the AQT anywhere in the CATV band permitting the current generation of digital  Televisions that are integrated with QAM tuners to easily tune and display the television picture. It also eliminates the need to reprogram or switch the input mode on the television every time a customer wants to switch between a standard digital CATV or off-air channel.

• 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. This is extremely valuable 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 receive 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 and 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.

The DHDP Series is a two-unit system consisting of a Downconverter unit which acts as the input section and an Upconverter unit which acts as the output section. Both units are housed in a single MICM style die-cast chassis and are available in both horizontal and vertical versions.

The Downconverter unit is designed to accept any 8VSB signal from 54-860 MHz. Channel entry is made using a 2 digit front panel accessible BCD switch. (I.E. - VHF 2-13, UHF 14-69 & unused spectrum 806-860 MHz). The Downconverter outputs an IF signal which is fed to the Upconverter unit.

The Upconverter unit is designed to take the IF signal from the downconverter and process it to any channel from 54-860 MHz. Channel entry is made using a 2 digit front panel accessible BCD switch. (I.E. - CATV – STD, IRC & HRC as well as Broadcast VHF & UHF).
