Blu-ray going 1440p and 50Mbs + bitrate ?

Thats why they will release blurays with 2 discs. One for the film and one for the extras

Actually 9 bits is 2.0 the levels of 8 bits. 16 bits is 256 times the levels of 8 bits.

What with all the talk on here about 1440P, I was just sitting back a while ago thinking about 1080 (I/P) and what was being proposed a few years ago as far as HDTV was concerned.

Japan proposed the Hi-Vision system which was 1125 lines, and broadcast this using an analogue compression system called MUSE. So this system had an additional 45 lines of resolution. They even launched a LaserDisc system onto the market using this format.

Europe proposed the HD-MAC system (which never took off) and this was a 1250 line system (twice PAL). So this system had an additional 170 lines of resolution.

Both used a similar aspect ratio, though I believe Hi-Vision was actually 5:3. I wonder what made the world plump for 1080 lines???
