A decoder like that should be a last-resort decoder, only in the cases where there's no other option. >> There are some good reasons for that, as it would allow in-kernel support for >> protocols that may have some patent restrictions on a few countries that allow >> patents on software. > > Are there any IR protocols less than 20 (or 17) years old? Yes. This protocol is brand new: https://www.smkusa.com/usa/technologies/qp/ And several new devices are starting to accept it. > If they are > older than that the patents have expired.
