Hi:
Just for my own interest, I would like to see some 10,920x10,080 pixel
progressive [non-interlaced] WMV video signals which have been produced
by sampling and quantizing SECAM analogue video signals in response to
sampling pulses having a sampling frequency of 15625 Mhz for the
horizontal sample rate, 500 Khz for the vertical sample rate, 425 Ghz
for the "blue" line subcarrier, and 441 Ghz for the "red" line
subcarrier. Despite the astronomically high pixel resolutions and
sample rates, the WMV coding should compress the color resolution so
much that no matter how long the WMV file, the file size will only be
1-bit. Obviously this would require some intense WMV color compression
after the WMV file has been encoded. After the WMV file is made, the
color-resolution is reduced sufficiently to make the file size only
1-bit regardless of the length of the file. This means a longer file
would require more intense compression than a shorter time -- e.g. a
5-minute WMV file would need more intense compression than a 1-minute
WMV file.
How would this video look like? I imagine that the pictures and their
motions would be VERY clear with no skipping. The only artifacts would
be those affecting the colors. These artifacts would be very extreme
because of the infinitisemly small color resolution. Do I guess right?
Thanks,
Radium
