So everybody is now excited about high-definition tv, but a japanese company is already testing a new video format with an monstrous resolution. Sounds so cool that i had to share with you guys, so here are the specs :
but i guess this 22.2 audio will be even better!! i cant wait for te-h future!!

Ultra High Definition Video From Wikipedia, the free encyclopedia
Super Hi-Vision, also known as Ultra High Definition Video or UHDV is a digital video format, currently proposed by NHK of Japan.
UHDV resolution shown in comparison to other digital video formats.The new format is four times as wide and four times as high (for a total of 16 times the resolution) as existing HDTV, which has a maximum resolution of 1920 × 1080 pixels. Because this format is highly experimental, NHK researchers had to build their own prototype from scratch. In the system demonstrated in September 2003 they used an array of 16 HDTV recorders to capture the 18-minute-long test footage. The camera itself was built with four 2.5 inch (64 mm) CCDs.
18 minutes of uncompressed UHDV footage consumes 3.5 terabytes of data and 1 minute of footage consumes 194 gigabytes. If 1920×1080p60 high definition video has a bitrate of 60 Mbit/s using current MPEG-4 compression technologies, then 4 times the width and 4 times the height will roughly require 16 times the bitrate. That would translate to 100 GB for 18 minute of UHDV, or 6 GB per minute. This would mean that a 12cm Holographic Versatile Disc at 3 micrometer separation of different colored tracks (with a capacity of 3.9TB) would be able to store roughly 11 hours of MPEG-4 compressed UHDV, compared to the 18 and a half minutes of uncompressed video.
Preliminary response of the UHDV was somewhat negative. This was not because of the lack of the promised technology, but more in the fact that it was too good. Some viewers got motion sickness when viewing the video image because the image was so close to reality.
In November 2005 NHK demonstrated a live relay of Super Hi-Vision (UHDV) program over a distance of 260 km by a fiberoptic network. 24 gigabit speed was achieved using DWDM (dense wavelength division multiplex) method with a total of 16 different wavelength signals.

i don't know why we need a faster frame rate, films all stick to 24, video is 29 and 25 in europe... faster frame rate isn't really needed since 24 is considered the ideal because the viewer fills in the gaps between in their head, thus involves the viewer more
also theirs a camera called the red camera in development to do this, but the goal is to get a digital camera that can record film's resolution... one that happens and film's depth of field can be achieved film will be done

I wonder what installing a 22.2 channel audio system in a home theatre is like
i love the idea of 2 subwoffers, one for the drums, other for the bass.

a professor at my school has run tests for 10.2, they put people in a dark room, and they could make the people think that there were crowds of people goin by

Two words:
Slow Motion
we don't need that in the tv just the camera... the camera records at the higher fps and when set to normal its slow, still plays at standard frame rate
