Now perhaps there is something obvious, but having been doing a load of stuff on signal processing, i can see no particularly good reason for us using digitally pre recorded material. The using of digital adds an inherent error to the signal in the first place, plus it forces the use of band limitations. It has the benefit that it is very good as far as not showing up noise.....but what does that have to do with the home environment!? For the most part, we send signal in an analogue manner anyhow! So.......major benefit of digital is that it does not degrade in transmission. (and i guess the media doesnt degrade). But, we dont use that. So why one earth do we use digital at all?! ad ps. im missing something arent i!?
