Xantech makes "special" IR receivers intended for operation
near giant noise sources (like modern TV's!) but they have
comparatively narrow angles of acceptance. 45 degrees is
a number you'll hear, and come to believe...
Niles says that all their current stuff is "plasma/LCD friendly"
but some issues of interference are pretty fundamental. The TV's
radiate amazing amounts of both RF and IR crap, and anybody
nearby has to deal with it.
One obvious solution is to remote the IR receiver and to then
have it be the *only* IR receiver, masking all room IR from the
devices' IR inputs, and allowing only repeated IR into each.
This can work well if an appropriate and intuitive IR receiving
location is available. Ceilings or other high locations
seem to be often successful, and are a treat to use.
Another, but maybe too elaborate, solution is a modern universal
remote that can communicate with a (proprietary) RF base. Some
siting isses can still arise; the RF base probably won't like to
sit near a cable box or a DVD player (although the newest
generations of RF bases are *much* improved). But all issues of
ambient lighting are removed, and there's "no pointing", itself a
small joy in operation.
This is an increasingly im****tant part of my current day-gig,
and I'm finding that the tactile and ergo parts are the most
im****tant to the homeowners who pay for my daily gruel, so
my emphasis is increasingly on learning what questions to
ask, and how to ask 'em. A tool that is used several hours
every day of somebody's life is a big responsibility, so a
certain effort both upfront and in follow-up is worthwhile.
Never tried to do it over the interent though... So...
How married are ye to the Sony remote? More to follow...
Much thanks, as always,
