目前目前.看起來.....
這次上市的新機種.
似乎沒有搭載期盼中:Bravia Engine 3 Pro 新型晶片
小弟本來以為.照理論會推出.2010新型影像晶片
看來.小弟搞笑了~
向各位道歉~道歉~
為何 2010年新機.還是延用 Bravia Engine 3 ????

回leonffx大~
就這次的W-LED背光規格來看...比較難有 X.V Color...
而Deep color應該會有才對...
是的....
沒Deep color的話...就是只能接收8Bit訊號...
有支援Deep color的話...就能接受10Bit/12Bit/16Bit訊號...
至於能支援到多少Bit就看該電視搭載哪顆IC了...
以下有講錯請糾正~
借用:Ida102大 的照片
以前的舊機種 Bravia 40W3100
就有 X.V Color 了
到 2010 NX800新機.現在卻沒有 X.V Color 嘛 ??????
請問有人知道嗎~
點我 Bravia NX800 官網
x.v.Color : 讓 HDTV 顯示色彩更精確，使色彩顯示更加自然、逼真
點我~MO1網站 x.v.Color 討論
要"來源"是 xvYCC"錄製"，撥放器支援 xvYCC，電視支援 xvYCC 三個同時有才可以。
Deep Color 目前實用性比較大。
拜託讀一下了解一下
不是用現今的REC709 HDTV色域把它擴大1.8倍就叫 xvYCC
有支援xvYCC的就可以顯示 xvYCC 內容。xvYCC是如何運作下面都有寫。
xvYCC or Extended-gamut YCC (also x.v.Color) is a color space that can be used in the video electronics of television sets to support a gamut 1.8 times as large as that of the sRGB color space.[1] xvYCC was specified by the IEC in October 2005 and published in January 2006 as IEC 61966-2-4.
xvYCC was motivated by the fact that modern display and capture technologies often have underlying RGB primaries with significantly higher saturation than the traditional CRT displays, allowing them to handle a wider color gamut. But these devices have been unable to do this without upsetting basic calibration, as all existing video storage and transmission systems are based on CRT primaries, and are hence limited to the CRT gamut.[2]
xvYCC-encoded video retains the same color primaries and white point as BT.709, and uses either a BT.601 or BT.709 RGB-to-YCC conversion matrix and encoding. This allows it to travel through existing digital YCC data paths, and any colors within the normal gamut will be compatible.
But xvYCC permits YCC values that, while within the encoding range of YCC, have chroma values outside the range 16–240, or that correspond to negative RGB values, and hence would not have previously been valid. These are used to encode more saturated colors. For example, a cyan that lies outside the basic gamut of the primaries can be encoded as "green plus blue minus red".[3]
These extra-gamut colors can then be displayed by a device whose underlying technology is not limited by the standard primaries.
In a paper published by Society for Information Display in 2006, the authors mapped the 769 colors in the Munsell Color Cascade to the BT.709 space and to the xvYCC space. 55% of the Munsell colors could be mapped to the sRGB gamut, but 100% of those colors could map to the xvYCC gamut.[4] Deeper hues can be created - for example a deeper red by giving the opposing color (cyan) a negative coefficient.
A mechanism for signaling xvYCC support and transmitting the gamut boundary definition for xvYCC has been defined in the HDMI 1.3 Specification. No new mechanism is required for transmitting the xvYCC data itself, as it is compatible with HDMI's existing YCbCr formats, but the display needs to signal its readiness to accept the extra-gamut xvYCC values, and the source needs to signal the actual gamut in use to help the display to intelligently adapt extreme colors to its own gamut limitations.
This should not be confused with HDMI 1.3's other new color feature, Deep Color. This is a separate feature that increases the precision of brightness and color information, and is independent of xvYCC.
xvYCC is not supported by DVD-Video or Blu-ray, but is supported by the high-definition recording format AVCHD and PlayStation 3.
