Ofcourse they do. They make their own restrictions. Restrictions mean 
simplicity and simplicity means a low-cost STB.

Now if youre talking pirated movies and that whole scene of video caps 
in 640x272 and other 'inbetween' resolutions, then you may have a point. 
But you aren't going to see these used anywhere except some 'dude's HTPC 
or PC.

If youre in the real world, good luck trying to convince the digital 
asset management folks that you want to support anything under the sun.

Newbie datacast rollouts have previously attempted the 'use any 
resolution' mechanism. Ofcourse the first thing to do is chuckle as the 
extoll the virtues of the type of system you envisage. Eventually they 
come to their senses and realize that it is more expedient and less time 
consuming to pick a short-list of standard resolutions and one codec and 
use this across the board. Anything else wastes time and money.

As for statmuxing VBR, you can do this already. You can use your 
automation system to control the encoders and flip them between SD and 
HD in the AM, or whatever the configuration is. All this stuff is 
addressable over IP these days - no rocket science there.

However, changing resolutions at every flip of the coin is likely to 
cause your STBs to fall over. Implementing such a system is an excercise 
in futility.
