I am a valet, and I have seen several people who cannot drive an automatic. Those people should lose their lisence. Have you ever had to explain to someone how to put it in "D", besides a first time driver?

What is Ultra HD?
Ultra HD stands for ultra high definition. It is a prototype for a new digital video format and is also referred to as ultra high definition video (UHDV). Ultra HD is the proposed replacement for existing high definition television (HDTV). The highest-resolution HD monitors currently available offer 1,080 lines of resolution in a progressive-scan format - also known as 1080p video. These screens have 1,920 x 1,080 pixels and are theoretically capable of displaying every pixel of the highest-resolution HD broadcasts. These sets are sometimes called “ultra HD” as a marketing term, but in fact are part of the current HDTV standard. True ultra HD is so named because it provides a video resolution containing 16 times as many pixels as current HD. Whereas HDTV uses 1,080 lines of resolution, ultra HD contains 4,320. Ultra HD uses 7,680 x 4,320 pixels in a widescreen aspect ratio of 16x9, making for a total of approximately 33 million pixels (33 megapixels). Ultra HD also offers improved sound quality: a 22.2 channel sound system reproduces 24 different channels of audio in three vertical layers of speakers, compared to currently available surround sound systems that use 5 or 6 channels. Ultra HD was developed by a Japanese public broadcast company and research group called NHK Science and Technical Research Laboratories. Their aim in designing ultra HD is to present images and sound realistic enough to give viewers the sensation of being part of the scene - one reason the ultra HD format is four times as high and four times as wide as HD. One screen built to demonstrate ultra HD spans 400 inches (10,160 mm). This provides viewers with a field of view perspective of about 100 degrees, compared to 30 degrees on commercially available screens. Some observers of ultra HD demonstrations have even reported vertigo. Ultra HD poses numerous practical problems for manufacturers seeking to bring the new format to consumers. The uncompressed video and audio recorded in ultra HD takes up high volumes of storage space - 3.5 terabytes for one 18-minute clip, requiring a hard disc weighing almost 600 pounds (272 kg). The prototype ultra HD screen can use more electricity than an entire house might in one month. An early ultra HD camera weighs more than 100 pounds (45 kg). Because of these issues, ultra HD will likely be used in large venues such as museums before and if it becomes commercially available. As it is still at the concept stage, it will likely not be available to the public for some years. NHK has an internal goal of getting ultra HD to market by 2025. It is now 2007, UHD want be around for a while. |

You're correct, HD will be around for a while, but as far as power needs and weight of required disc storage, etc., I don't take much stock in statements like that. Technology and research is providing us with new ways and means to do what was impossible just 3-5 years ago, and I'm pretty sure that the future will provide the same opportunities. |

It is true btw that HDTV was first pioneered in the 60s/70s (I think 70s.) It just wasn't really successful until recently. Heard it on the HT guys show.

Hell yes..... Ultra HD..... But I'm sure the DVD Forum will squeeze a U-HD movie onto a 30gb disc with an ultra low band width and a Mono Sound track.....and market it as 'adequate but affordable' ....

Ultra HD is for theater only. The highest I see for home use is 2160p. Four time more resolution then 1080p. What more would anyone want.

If "Ultra-HD" is real, we MAY be alive by the time it becomes available. Look how long it took HD to gestate, and it is still the minority format. Japan's NHK was developing a version of HD in the mid-80's that never really got fully off the ground. The FCC started soliciting proposals in the late 80's for what is the now the current HD formats - almost 20 years later! I think the average consumer is going to be pretty happy with 1080P for along time, considering that most of them are still happy with his NTSC standard TV and DVD's that have a maximum 480 lines of resolution. So I wouldn't make too many plans on upgrading my 1080P set just yet.
