Mitsubishi and others are promoting a technical standard that's expected to greatly expand the color palette on televisions.
The standard--elegantly called xvYCC--is meant to update the televised color spectrum for the Digital Age. The current standard, BT.709-5, defines the ranges of reds, greens and blues that TVs can display. The new standard will broaden the range of colors, adding shades of cyan or bright green, which should lead to more natural-looking colors.
"You'll be able to see richer and more colors," Vik Murty, senior manager of product marketing at Mitsubishi Digital Electronics America, said during a presentation Wednesday at audio and entertainment tech specialist Dolby Laboratories in San Francisco. "This opens a new set of colors that no one has ever seen on a TV before."
Mitsubishi plans to incorporate the standard into TVs beginning in April. Broadcasters are also starting to build xvYCC-compliant systems so they can deliver programming that takes advantage of the standard. Others are working on it too: Sony showed off small screens with the technology earlier this year.
Mitsubishi also plans to come out with a
TV that uses lasers, rather than lightbulbs or LEDs, as a light source in late 2007, he added.
The new standard will further be enhanced by Deep Color, an existing technology that smoothes out the fine gradients between shades of colors. In some older digital TVs, viewers can see faint bands in a color field as the colors get lighter or darker. In a TV with Deep Color, the bands disappear, and images in shadows become clearer.
The acronym xvYCC is a rough equivalent for the standard more formally called Extended YCC Colorimetry for Video Applications. The standard is governed by the International Electrotechnical Commission.
