Thanks for adding these. Can you share the context in which these are used and your source for identifying the friendly-name mapping?

Hi,
I took those from https://code.google.com/p/dacp-net/ not sure if naming is accurate to some standard but they make sense when testing. Might be Apple specific tho...

In any case thanks for your work, made my life way simpler doing https://github.com/RolandasRazma/RRTouchRemote
