Help with Understanding Profiles

I'm not quite understanding how to read the profiles.

The default Panasonic Viera 2011 profile that's in profiles.xml is pasted in below.

My Viera E can certainly play many file formats without the need for any transcoding. Where in the profile does it tell Serviio which files to NOT transcode? Or is is just transcoding everything and the profile is pretty much there only to tell Serviio what format to transcode to?

This profile inherite of viera2011a profile, so you also have to read this profile.

Got it now.

Can someone help me figure out what the Panasonic viera 2011 does with an .mkv/h264/DTS video?

Is it passing through the video with no transcoding and then transcoding the audio only to lpcm?
