One HDD Installation Manual
2. PRODUCT DESCRIPTION
The HDD is an ATSC/QAM professional grade rack demodulator designed for cost effective
digital-to-analog conversion of an unencrypted 8VSB (Off-Air SD/HD TV signal) or QAM
unencrypted (digital CATV) RF signal to baseband NTSC video and left and right stereo
audio outputs. All of the 18 ATSC video formats including HD format can be received by the
HDD and converted to display on non-digital TV sets over analog channels with the use of a
modulator
