原文+部分翻译:The High-Definition Multimedia Interface (HDMI) specification, a key component of digital television, has been upgraded to support "deep color," the group controlling the interface said Monday.
星期一,HDMI协会升级的现有的HDMI规格,新的HDMI1.3规格将支持高精度色彩

HDMI LLC, which was founded by Hitachi, Matsushita Electric (Panasonic), Royal Philips Electronics, Silicon Image, Sony Corporation, Thomson and Toshiba Corporation, oversees the HDMI interface, which has served as the multimedia interface for digital television. Over 400 firms have licensed the technology, and the firm estimates that 1 billion HDMI-compliant devices will be available by 2009.


Under the new HDMI 1.3 specification, the clock speed will be increased from 165 MHz to over 225 MHz, said HDMI president of licensing Leslie Chard. The increased bandwidth will allow support for 1080 x 60 Hz displays with 36-bit RGB color, or a 1080p display with a 90 Hz refresh rate. Technically, the specification leaves room for clock rates of up to 450 MHz, Chard said.
HDMI1.3版的频率将从165Mh增加到225Mhz,增加的带宽将支持1080i x 60FPS x 36-bit RGB (现有的都是24bitRGB,8bit/红绿蓝),或者是1080P x 90FPS。

The new standard will add a new upgrade path for digital television owners and buyers. Very early DTVs lacked an HDMI connection, leaving early consumers with concerns over whether or not they would be able to play protected content. Now, the new specification promises an enhanced level of detail for next-generation content. According to Chard, a few early adopters should announce products soon, Chard said, with "lots of products by the end of the year," in time for Christmas, he said.
对于早期拥有高清晰电视,但是没有HDMI的用户不用担心,新的HDMI规范将允许通过省级的方式解决兼容性问题(不太懂这一段的具体意思)

The key addition to the new specification has been the support for 30-, 36-, and 48-bit RGB or "deep" color, a specifcation that extends color depths beyond the capability of the human eye to perceive them.
最主要的增强就是对30/36/48bit RGB高精度色彩的支持,这将会冲击人类视觉的极限

The ITU 601 standard, which governs today's displays, allows only 60 to 80 percent of the available colors, even if the display can support more, Chard said. "The color bit depth [of today's displays] is typically 24-bits RGB – that gets you 16 million colors, and the human eye can distinguish that," Chard said. "That leads to scaling and onscreen effects which you can pick up. Either 36-bit or 48-bit RGB is beyond the ability of the human eye to distinguish."

Sony's upcoming PlayStation 3 will support deep color, Chard said, and PC graphics companies like ATI and Nvidia can bake the technology fairly easily into its cards, he said. Although the "deep color" provision was added with the next-generation Blu-Ray and HD-DVD specifications in mind, no formal announcement of support has been made by either camp.
PS3将会支持高精度色彩,ATI/nV也在试图利用这种技术。

"We don't have a public announcement, but it's natural to assume as standards get big and are accepted that they may be used," Chard said. "Anybody going to have an HD-DVD or Blu-Ray drive needs to have an HDMI output," Chard added. "Anyone who's claiming to have a media notebook needs to have this."
这种HDMI的标准将在未来普及,所有的HDDVD/BD都会有这种接口(PS3的廉价版怎么办??个人感觉Sony会在GDC宣布在廉价版中加入HDMI接口,以平民愤


The new color depths will be consistent with the new "xvYCC" color scheme which was adopted as a standard by the International Electrotechnical Commission in January. Sony showed off a xvYCC-compliant 82-inch LCD at this year's CES.
这种高级度的色彩可以兼容现有的xvYCC。

The standard will also add support for Dolby HD and DTS-HD audio. The audio will be combined with a lip-sync compensation feature to synchronize the audio and visual channels -- not actively, but through the use of latency information which will will be actively communicated to the other components, Chard said. Finally, support for an HDMI mini-connector has been added, to allow digital video to be streamed from a compliant camcorder directly to a display.
新的标准可以支持多种声道环绕系统。

Finally, future displays will support what is known as "Consumer Electronics Control," a standard that will allow the HDMI devices to talk to one another, and configure themselves. The most profound effect will probably be the phasing out of the high-end remote control devices, which will be replaced with a simpler control scheme, Chard said. The technology may be marketed as "One-Touch Play," he said.

The HDMI interface is often thought of as the hardware component to the High-Definition Content Protection standard, which is governed by a separate licensing organization. No HDCP-specific provisions were made, Chard said, although the new HDMI spec "caused a few bugs" in testing with HDCP, he said.
HDMI和HDCP的标准现在还在测试当中,目前兼容性尚有问题,有待改进。.

经过一轮又一轮的缩水之后终于某个地方进行了升级
可惜的是 阉割版享受不到这种升级

36bit色彩好像对LCD没意义吧,
再高档的LCD电视或显示器都只有24bit,16777216色。

假的,PS3规格已经不断缩水了,怎么还会有进步呢?某业内人事说PS3不支持16:9了
