Oh donâ€™t look for it at next years NAB it Took 40 years for HDTV
to happen and will likely take at least 1/2 as long for this to

Will there be a 24p variation?
I like more spatial and hate more temporal.

One can presume so. IMHO there's going to be a real need for it
to replace IMAX - without the volume of 35mm, it's going to be kinda
difficult to maintain any kind of 65/70mm infrastructure into the
future. And the resolution is about right - probably overkill for
It's worth noting that one shoots very differently for immersive
formats. You're typically concerned with the centre third resolution,
so that's only 2560 pixels wide in the viewing area.

I wonder how they plan to distribute it.
Four times the Horizontal line count means sixteen times the data
rate! It could only realistically be a disk-based system, but you'd
need 64 of today's dual-layer DVD's to store one movie!
However, 4,000 line wall-sized screens may be a lot closer than
you think, what with the new printable Light Emitting Polymer technologies.
And 4,000 lines is only about 9 times the height of a standard NTSC
screen with the same line pitch. I always thought 1,000 lines wasn't
enough of an improvement to worry about...

Or a 64:1 compression ratio. Does anyone know what the compression
ratio is currently for digital cable?

Not an answer to the question -- Jessica was asking about the horrific
compression that is used on current cable systems, which is so bad
that any fade or dissolve turn into a symphony of mosquito noise.

Very true - my mistake. I believe typical DTV broadcast is 19.5
Mb/sec for HD which is an enormous amount of compression from the
even HDCAM at 140 Mb/sec which is already about 7:1 compression.
And cable systems would probably add more compression.
So, from camera to viewer on a cable system, you probably won't
see BETTER than 50:1.
