The Blonder Tongue DAP (Digital/Analog Processor) accepts one input in 8VSB (digital off-air) or QAM (digital cable) format, and delivers one output in modulated analog RF format. DAP PLUS is the same as DAP, but includes the AFD broadcast package. AFD (Active Format Description) is a standard set of codes embedded in the video stream and used by digital television broadcasters to optimally display a 16:9 video format on an analog television set designed for 4:3 video format.
Blonder Tongue DAP Plus Series
The Blonder Tongue Digital to Analog Processor Plus (DAP Plus # 6295) is a complete single channel solution for delivering digital television programming over existing analog networks. The two additional features that differentiate the DAP Plus are the Broadcaster Firmware package and the ability to add an optional Asynchronous Serial Interface (ASI) output. The Blonder Tongue DAP Plus is a perfect transition unit for existing analog processors to ensure uninterrupted delivery of off-air signals from new digital broadcast sources. The cornerstone of the Broadcaster Firmware package is the ability to process Active Format Description (AFD) that is inserted by some broadcasters. Broadcasters deploy AFDs to control the timing of Aspect Ratio switches more accurately than using MPEG signaling alone.
The Blonder Tongue QT Series (QAM Transcoder for DISH Network) is the latest Blonder Tongue Transcoder product and it features the ultimate combination of optimum balance of price per channel and top notch performance and functionality. This new Blonder Tongue QT incorporates a scalable modular design that allows from one to eight transcoder module sections as well as a single combination power supply & control module to be added, removed or swapped at any time. Support for redundant back-up or standby power has been built into every QT power supply & control module.
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 Blonder Tongue 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 Blonder Tongue ASI-4 is a 1:4 active ASI splitter. It is designed to complement digital headend products that can utilize an ASI input for EAS (Emergency Alert System) applications, or any application requiring splitting of an ASI signal. The ASI-4 can be deployed in a daisy-chain configuration to provide additional outputs as required. Modular design allows installation of up to six units in 2RU.
