Yes, but the pipes are getting a little fatter (we may get 30 Mbps or more with DVB-T2), and satellites have even higher potential bandwidths.

And what makes you think that this extra bandwidth will be used to satisfy the needs of a tiny fraction of the marketplace?

The use of bandwidth in any distribution system is an economic, NOT a quality decision. Unless you can show us how the very small percentage of consumers who own displays that can actually resolve any increased resolution in a 1080P encoding

And the new codecs are only at the beginning of their improvement curve.
So why restrict us to the lower figure ? The 1080 format is designed to be close to the eye resolution limit under a 30 ° angle which means we should be able to perceive the increased sharpness.

Because 98% of the marktt will use display technology at the lower figures, and the content will look as good or better on the small number of really big screens because the distribution pipes are NOT going to be used to satisfy the needs of a few percent of the audience.


I am all for a flexible system that could span all the way from a single H.264 1080p using the full 30 Mbps (should make for a nice picture, on a par with HD-DVD or Blu-Ray) down to CIF format (352x288) in a 250 kbps BPSK modulated signal with ultimate error correction codes to punch through the geomagnetic storm of the century...(though i suspect little money would be invested to get ready for this particular case :-)

We've already been through that of course, but the price of the electronics to do this have further decreased since the last time.

I've watched Blu-Ray. The extra detail is only useful for VERY LARGE SCREENS. On a 40-50 inch screen there is little extra detail when compared with standard DVD.

There will be ways to deliver higher quality images to videophiles. DTV is NOT one of those ways.
