Yes, UK uses FreeSat's huffman codes. There are some open source programs that
implement it. The huffman decoding itself is OK. The problem is that Freesat
use some char tables that seem to be under some copyright protection. Adding it
to Kaffeine (or to libdvbv5) could cause some legal issues, with would prevent
distros to be able to ship it.
The best would be to have some sort of plugin that would allow someone to
download such tables and/or a huffmann parsing library. Unfortunately,
currently, I don't have time to work on such code. If someone wants to develop
it in a way that would keep the Kaffeine code clean of legal issues, I'll
gladly apply it.
