briantist, your knowledge of moore's law is very poor. What it says is that the number of transistors doubles every 2 years. This is processing power, it has nothing to do with cost of the processor nor encoding quality.
The way the bbc increases the quality of mpeg4 over time is by implementing more of the mpeg4 spec which was created many years ago, this is very time consuming to do to maximise quality of the video by having the pixels analyse those around them and countless other techniques which take years to fully implement. New encoders are released with more and more of the specification completed, a bit like firefox adding more of the html5 specification.
The bbc will be able to increase the quality of video with the same bitrate a little over time but not by an enormous amount, the bbc is lying by saying they can fit 5 hd channels on the mux and there be no difference in quality. The same as when they dropped the bitrate from 16mbps on satellite to around 9 and said as a result of new encoders there was no difference in quality, this was a lie, screenshots of the same tv shows prove it.
btw 12% of brits can't see 3d and get headaches as a result, this is because their brains can't see 2 seperate images. One of the countless reasons why 3d is just a gimmick.
I'd rather we keep 4 hd channels on the mux and wait until another mux is opened until more hd channels come on freeview hd otherwise the quality will be way worse than it is now. Freesat hd is around 8mbps average, freeview hd is around 6.4mbps average so the quality is way worse as it is.
