Contemporary Research 3 232-ATSC Digital HDTV Tuner
The 232-ATSC HDTV Tuner is an integrator-friendly universal HDTV tuner, controllable via two-way RS-232
and discrete IR commands. Able to fit two-across in a 2RU rack space, the compact tuner outputs HDMI,
RGB/Component, and composite video simultaneously. NTSC broadcasts are upscaled for HD display. Digital
audio is available from HDMI, coax, and optical connections, as well as variable-level stereo audio. Setup is a
snap, employing on-screen menus, included IR remote, front-panel programming, and RS-232 control
commands.
For home theater applications, the 232-ATSC offers no-compromise full-bandwidth image quality of local
HDTV broadcasts and can access multi-channel programs - features not supported by over-compressed cable
and satellite "HD" programming.
For commercial installations, the 232-ATSC tunes in today's and tomorrow's programming, and can receive
conventional cable channels as well as local HDTV broadcasts from an off-air antenna.
