And this "it's digital" argument is bogus. The individual bit is either transmittes correctly or not, but the whole stream can have arbirary many bit errors which the receiver can only compensate up to a certain rate. There is usually good error correction on the audio streams (both listeners and speakers don't react well to sudden loud clicks), but errors in the video stream usually lead to artefacts that may be visible for are few fractions of a second or so (until the next full frame in the streams). Whoever makes this "digital streams cannot degrade" argument has obviously never tried to watch DVB-T behind a hill.
