The trend: Slim, light laptops that can play back high-definition video—and edit it—30 percent faster than before.
Video is becoming harder to manage. The popularity of Blu-ray discs, 3-D video, and high-def camcorders and cellphones means PC users need portable power. So Intel and AMD are cramming graphics processors into the space that normally houses only the CPU. Each 1.5-inch chip can hold nearly a billion transistors, which move and render video data quickly, while a dedicated area handles more demanding tasks, such as editing high-def footage.
Like all A/V gear, dirt-cheap Blu-ray players can suffer from flaws caused by poor construction and cheap components. Once you’ve moved up from sub-$100 models to name-brand equipment, though, picture-quality differences are subtle.
Flat-panels were supposed to eliminate the hulking television cabinet. But they are tethered to boxes -- cable tuners, disc players, A/V receivers -- that fill a big piece of furniture. A wireless connection lets you at least stash those peripherals out of the way. We tried out the first two cable-free HD technologies: one that uses radio waves and another that piggybacks on your home's electrical wiring.
We compare three high-definition compact cameras to see which
captures the most cinematic footage

New point-and-shoot cameras capture video in the 720p high-def format you've seen on TV networks such as ESPN. But all HD is not equal. The algorithm, or codec, that compresses the video onto a memory card affects the quality of the footage and your ability to edit it. We tried out three cameras, each sporting a different codec, to find the best mobile movie rig.
Makes way for the real high-def battle: disc vs. download

February 19, 2008 is Confirm the Obvious Day. Pervez Musharraf finally had to concede that nobody in Pakistan likes him. Castro acknowledged the fact that he hasnt been running the country for over a year. And Toshiba fessed up that theyve lost the high-definition movie war.
Construct a high-def front projector for hundreds less than store-bought models

Want some real home theater bragging rights? Instead of buying a projector capable of casting a 14-foot image at 1080p (progressive) resolution-the highest high-definition there is-build one yourself. After all, the front projector´s innards are simple: an LCD lit by a superbright lamp, and a few lenses to magnify and sharpen the image. Retail models start at around $800 and use proprietary $400 lamps that burn out every few years. But cheaper lamps work equally well, and none of the other parts are very expensive. Why not put one together yourself?
Transparent OLEDs could turn your living-room window into a high-def TV
By Elizabeth SvobodaPosted 03.13.2006 at 2:00 am 0 Comments
Sleek, wall-mounted plasma screens might seem like viewing nirvana now, but what if a picture window could double as a flat-screen TV? Or what if your car´s GPS system could be displayed on your windshield? Researchers at the Fraunhofer Institute in Germany have invented a transparent OLED (organic light-emitting diode) that will allow just that, transforming any clear surface into a see-through display.
Toshibaâ€™s Blu-ray-driven breakthrough HD player is ready to roll

HDTV sets are stunning—until you pop in a movie and are reminded that DVDs are not recorded in high definition. At 480 lines of resolution, they don’t even begin to take advantage of a 720- or 1,080-line display. That will change later this year when Toshiba introduces the first high-def disc player for the U.S. market. Toshiba’s breakthrough box, an HD DVD player that at press time was still unnamed, will cost about $1,000 (toshiba.com).
