Ok, i learned yesterday that Digital was old fashioned, which does in a way make sense because the waves are very basic (compared to analogue. Also i learned that Digital TV cut out around 95% of the information that would appear on an analogue wave. Instead of focusing on expanding digital processes, why cant they research improvements on analogue? I know that analogue waves are are subject to interference and when signals are picked up, there is a lot of background noise, so why cant we une UHF (ultra high frequency...if that exists) waves to counteract the wavelengths of background noise? It seems like a step backwards to have to use digital technology. Which leads me to my next question what is going to be different between MPEG2 and MPEG4, is it just gonna be minor tweaks to quality or are there gonna be radical changes?
