As suggested by randman, read my original document and you will gain insight.

I have proprieatary tools that I developed that are heuristic in nature, as opposed to algorithmic. They compare IR patterns in several formats and deduce timings, attempt to ascertain a "1" from a "0" and match a known protocol to the pattern. because of their heuristic nature I have never released them as they require a user with an intimate knowledge of IR patterns and protocols to assist in guiding the heuristic.
