The Future |
You can buy this TV right now for about $2000. A television set for which there is no content has never been for sale in the history of the medium. Let's back up a bit... |
These are the relative sizes of
various picture formats in use today. The "DV" frame is what
we had in standard-definition digital television. The next two are what
we have in use as "HD" television. 1280 x 720 pixels,
and 1920 x 1080 pixels.
The 2 and 4 "K" are used for theatrical release of movies. They are 2000 x 1000 pixels, and 4000 x 2000 pixels. Notice that they are not in the 16:9 aspect ratio of our television images. They are 2:1 4K is generally used for shooting and mastering movies, and 2K is what you watch in most theatres. 1080 is very close to 2K... 1920 pixels wide compared to 2000 pixels wide. Consumer "4K" sets are actually 3840 x 2160 pixels... exactly twice as high and wide as 1080 HD. They are not 4000 pixels wide, and I can't help thinking of the zone plate. |
