00:00:00,480 --> 00:00:03,560
Speaker 1: Welcome to brain Stuff from house stuff works dot com,

2
00:00:03,560 --> 00:00:08,440
Speaker 1: where smart happens Hi and Marshall Brains. Now that everyone

3
00:00:08,560 --> 00:00:10,680
Speaker 1: is getting used to h D t V and more

4
00:00:10,720 --> 00:00:14,000
Speaker 1: than half of US households actually own a digital TV,

5
00:00:14,640 --> 00:00:17,800
Speaker 1: manufacturers are starting to toy with the next big thing

6
00:00:18,440 --> 00:00:22,079
Speaker 1: right now. It's called Ultra high Definition or u h D,

7
00:00:22,280 --> 00:00:25,840
Speaker 1: and several companies are already selling u h D screens.

8
00:00:26,440 --> 00:00:30,440
Speaker 1: A standard hd TV screen has nineteen twenty by ten

9
00:00:30,560 --> 00:00:34,280
Speaker 1: e D pixels, or roughly two million pixels per frame,

10
00:00:34,760 --> 00:00:39,000
Speaker 1: and Ultra high definition screen has four times that many pixels,

11
00:00:39,120 --> 00:00:42,960
Speaker 1: or eight million pixels per frame. It's like putting four

12
00:00:43,240 --> 00:00:47,160
Speaker 1: hd TV screens on a single display. The problem right

13
00:00:47,159 --> 00:00:50,120
Speaker 1: now is that there really isn't that much video at

14
00:00:50,159 --> 00:00:54,760
Speaker 1: that resolution to display on Ultra high Def TVs. Manufacturers

15
00:00:54,840 --> 00:00:58,320
Speaker 1: end up demonstrating the TVs by putting up eight megapixels

16
00:00:58,360 --> 00:01:02,200
Speaker 1: still images from digital cameras. Japan is working on the

17
00:01:02,200 --> 00:01:06,119
Speaker 1: next step beyond that, called Super high Vision. It has

18
00:01:06,240 --> 00:01:09,679
Speaker 1: four times as many pixels as Ultra High death, or

19
00:01:09,880 --> 00:01:14,240
Speaker 1: thirty three million pixels per frame. At that resolution, It's

20
00:01:14,280 --> 00:01:17,440
Speaker 1: hard to find even still cameras with enough pixels to

21
00:01:17,480 --> 00:01:21,720
Speaker 1: fill the screen, but Japan claims that by tween, super

22
00:01:21,840 --> 00:01:24,880
Speaker 1: high vision will be coming online. Do you have any

23
00:01:24,920 --> 00:01:28,560
