YCbCr係色差訊號,色階範圍由16至235
RGB色階範圍由0至255

MTV 無論set RGB or Ycbcr 都好似相差無幾 too.Using Kuro 500A.
BTW, do you use 1080i or 1080p.I feel p has a little bit lag, very very small.

如我無記錯!!
RGB : 0~255
YCBCR : 16~235
兩者在灰階上有所不同 ,
而且RGB 好似係set-top box 內解後才輸出至tv ,
而YCBCR 則是把訊號輸出至tv給圖像處理器內解,
理論上 , 如果部tv唔差的話 , 應用YCBCR比較好{:6_142:}

今日睇左新一期電腦廣場,佢係BDP介紹個度底下有個小TIPS,話由於RGB色域係寬D,所以揀RGB會好D!

Let me tell u guy the truth.
Pick YCbCr
Why?
Some magazines said the range of RGB is wider than YCbBr.Yes, it is truth.However, it doesn't mean that you pick RGB which can give you the best picture.
From the view of the history, all color encoding of DVD, bluray and TV broadcast are using YCbCr, so no transformation is needed if you pick YCbCr.
When you pick RGB in your MTV3000, (0-15) and (236-255) is needed to fill data.What does it fill?Please ask MTV programmer.
What will be affected for these filled data?The answer is grayscale of each color.In other word, it is the intensity of each color.
Hint:When you are going to calibrate your TV, please use YCbBr. It can help to reflect the truth color from the source.
