Samsung C/D/E television, are my movies being retranscoded?

Hi,
I have a Samsung television and a few movies in a few different formats, from 480p to 1080p. Then I saw this line:
Now, I'm no big expert in all this, but does this mean my 1080p mkv movies are being retranscoded to something lighter, like 720p or 1080i? Because if they are, I will stop getting my files in 1080p and target a lighter format, and save bandwidth at the same time.
Thanks!
