UHD: Ultra-High Definition TV to Feature 7680 x 4320 Pixels

259w ago - This holiday season most will be trying to replace their DVD players with Blu-ray and their nice plasma flatscreens with HDTVs.

However, the industry already is worrying about the market for UHD – Ultra-High Definition.

Apparently, UHD will debut in the next five to 10 years, but is expected to take a long time before it reaches a "critical mass," deemed to be taking up residence in 5 percent of households globally, according to market research firm In-Stat.

To quote: UHD will come in two resolution levels: 7680 x 4320 pixels (8K) and 3840 x 2160 pixels (4K) and provide four to 16 times the resolution of Blu-ray or 1080p high-def. And "22.2 multichannel three-dimensional sound."

In-Stat's study concluded that high resolution digital cinema would drive consumers to UHDTVs so they could experience the same quality on their home television sets and that broadcasters would start providing content in the lower-resolution UHD by 2017 and the high-resolution technology by 2022. The market in Europe is expected to hit 5 percent penetration by 2021 and then zip up to more than 28 percent by 2025.

Ultra HDTV Requirements:

• Ultra HDTV requires 300Mb/second transmissions using a compressed image at 24 FPS, while 60 FPS will require a new compression system...
 

PSP-3000 Screen Issues Investigated, Poor Pixels Suspected

100°
312w ago - Logic-Sunrise has shared the results of their investigation into the screen issues with the latest edition PSP-3000 consoles.

They took out a microscope in order to test the difference between the screens as follows:

On PSP-3000 and newest PSP-3004, Everyone get a "bad screen" (scanline effect). But what happen on these screens ? in fact we get a microscope, and we tested differencies between old good screens, and newest bad screens.

In fact, after looking it 40X bigger, we can see all pixels. As you know, a pixel got 3 colors : blue, green and red. The biggest issue is the blue part of the pixel is not "light", but very dark, near black ... The or issue is that the blue part is horizon aligned, not vertical aligned, like old screens. It's why we have a scanline effect.

Also, we contacted SONY: No new console will be changed or screen replaced. We made a simple: gaming. It's VERY awful to play on these console, and we recommend everybody to bye old slim psp (psp-2004 for exemple) or wait for new screens on PSP 3000 and psp 3004 consoles.

We made 2 pictures, to compare.
