Quality of experience¶

Firstly, the human has limitation of its physical capacity with the eyes and the ears, we cannot ear and see everything therefore we are not able to see/ears the imperfection introduces by the channel of communication.

Secondly, with the improvement of movies qualities, we are more and more reluctant to watch a movie in bad quality (480/576p) while 10 years before that was the the movie's quality.

The previous table shows us the resolution increase of movies during the latest years, therefore the quality of experience increase too.
