Philips offer good documentation for the RC-5 protocol used in their
domestic products and, I think, a number of other manufacturers. This
appears in a booklet called "Remote Control System RC-5 including
command tables" published in December 1992. There may be some example
code around for this on the net, too, though I'm not sure where.

Sony use a different protocol : as far as I know it's still the system
described near <http://pasture.ecn.purdue.edu/~laird/Sony/index.html>.
