that would be this.... dont hold your breath though!
from wikipedia....
Super Hi-Vision, also known as Ultra High Definition Video or UHDV and UHD
is a digital video format, currently proposed by NHK of Japan.
Super Hi-Vision's main specifications:
Resolution: 7,680 4,320 pixels (16:9) (approximately 33 megapixels)
Frame rate: 60 frame/s.
Audio: 22.2 channels
9 - above ear level
10 - ear level
3 - below ear level
2 - low frequency effects
Bandwidth: 21 GHz frequency band
600 MHz, 500~6600 Mbit/s bandwidth
UHDV resolution shown in comparison to other digital video formats.
The new format with a resolution of 7,680 4,320 pixels is four times as
wide and four times as high (for a total of 16 times the pixel 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
with a combined resolution of only 3840 2048. They then resort to pixel
shifting to bring it to 7680 4320.[1]
18 minutes of uncompressed UHDV footage consumes 3.5 terabytes of data and 1
minute of footage consumes 194 gigabytes. If 19201080p60 high definition
video has a bitrate of 60 Mbit/s using current MPEG-2 compression
technologies, then 4 times the width and 4 times the height will roughly
require 16 times the bitrate, which translates to 100 GB for 18 minutes of
UHDV, or 6 GB per minute if MPEG-2 video compression was used. If H.264
(MPEG-4 AVC) or VC-1 video compression technologies was used then roughly
half the bitrate of MPEG-2 would be required to achieve the same quality,
meaning 50 GB for 18 minute of UHDV, or 3 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-2 or 22 hours of H264 or VC1 compressed UHDV,
compared to the 18 and a half minutes of uncompressed UHDV. Additionally, an
eight layer Blu-ray disc (with a capacity of 200GB) would be able to store
approximately 36 minutes of MPEG-2 compressed UHDV, or 72 minutes of H264 or
VC-1] compressed UHDV, compared to the 1 minute of uncompressed UHDV. A 50TB
Protein Coated Disc would be able to hold over 94 hours of H.264/AVC/VC-1
compressed UHDV, but generally that would be unnecessary, for a 50TB PCD
would be able to hold 4 hours of uncompressed UHDV. Once Stabilizing
Ferroelectric Materials is accomplished it would be able to store 1024 hours
of uncompressed UHDV and 24064 hours of H.264/AVC/VC-1 compressed UHDV.
