@opon4: Thanks for clarification ! Patented is the right term. Sorry for
choosing the wrong word. But in the end this does not change much the mayor
point of my posting :)
There are open & free options like Opus, FLAC, the Ogg stuff but they usually
lack support throughout the available devices.
Example: If I give away a movie of my litte one to my parents, they can
easily play back a file using patented formats / codecs (1080p in MP4
container using h264 and AAC) in their DVB-S2 receiver with external HDD
while they could never play back a 1080p MKV file with VP8 for video and FLAC
for audio.
