As you have of course experienced, most video devices make zero provisions for non-visual user interfaces. So I might (perhaps incorrectly) assume that every setup interface you will encounter, from connecting the converter to scanning for channels receivable by your antenna, are going to rely exclusively on screen-based menus. The paths you must take to address such obstacles I can barely grasp.

Treviranus
and the inclusive design team at OCAD. What they are doing is just incredible, but the challenges and inertia they encounter are even more incredible.
