AQD (ATSC/QAM Demodulator) accepts one input in 8VSB (digital off-air) or QAM (digital cable) format, and delivers
one output in NTSC composite analog Audio/Video format, and two identical outputs in ASI format.

AQD allows delivering of a digital off-air program to viewers with an analog TV set. It also allows an operator to cher­ry-pick channels from a “clear” QAM cable lineup.

AQD PLUS is the same as AQD, 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.

Features

• Input standards supported are digital off-air (8VSB) and digital cable (QAM 64 and 256)

• NTSC Composite Analog Audio/Video output is in 480i format and supports Closed Captioning (EIA-608)

• Optional AQD-RCS module allows remote monitoring and configuration of up to 80 AQD modules

• Optional AQD-SPS unit provides standby utility power to the primary power supply (AQD Power & Control module)
