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 Dolby® 5.1/PCM 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 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. See Tuning Digital Cable Channels to learn how to determine which cable channels can be tuned in your installation.

RS-232 or IR control. Automation must be expensive. When AVSForum doesn't even have an "Official Thread" on it, it must be a pretty rare piece of HT equipment.


Not a big seller I'm guessing. :) I'm just trying to figure out why it costs $700-$800 more than comparible HD tuner's without RS-232.

Two clues. One is rack mountable. Two is RS-232 control.
This can be used in a commercial environment where you have a separate computer doing your scheduling if used in a cable head end or studio.

Hence it's commercial equipment that greatly inflates the price.
