Agreement.SiI8630 chips can built-in 1/3DSC IP, the compression of rgb format data is realized while transmission, reduces data
Amount, spread bandwidth.In addition, SiI8630 chips also support the up-sampling (up- of coloration (Chroma) in addition to supporting 1/3DSC compressions
Sampling)/down-sampling (down-sampling) is realized by coloration down-sampling by YCbCr 4:4:4 format compressions at
YCbCr 4:2:2 formats reduce data volume, spread bandwidth.
YCbCr (also referred to as YUV) is a kind of colour coding method (belonging to APL standards) that the prior art uses, and is mainly used for
The transmission for optimizing colour-video signal, compared with rgb video signal transmits, great advantage is to only take up few bandwidth,
And RGB requires three independent vision signal simultaneous transmissions.In YCbCr, Y represents brightness (Luminance), i.e. grayscale value,
Cr and Cb represents coloration (Chrominance or Chroma), defines two aspects of color：Tone and saturation degree, are used respectively
Cr and Cb indicates that Cr reflects difference between RGB input signals RED sector and rgb signal brightness value, and Cb reflections are
Difference between RGB input signals blue portion and rgb signal brightness value, i.e. colour difference signal.YCbCr format mainly has YCbCr
4:4:4、YCbCr 4:2:2 and YCbCr 4:2:0.Wherein, 4 YCbCr:4:4 formats refer to that three kinds of members are known as same resolution
Rate, YCbCr 4:4:4 formats completely remain all values of information.YCbCr 4:2:In 2 formats coloration element it is longitudinal with
Brightness value has same resolution ratio, and in the half for being then laterally brightness resolution, i.e., every four brightness values there are two Cb and Cr,
Commonly used to construct the video color signal of high-quality.YCbCr4:2:0 format is not meant to only Y and Cb without Cr points
Amount, it refers to for every horizontal scanning line, and only a kind of chromatic component is with 2:1 sampling rate storage, the storage of adjacent scan line
Different chromatic components.That is, if a line is YCbCr 4:2:If 0, next line is exactly YCbCr 4:0:2, then under
A line is YCbCr 4:2:0... and so on.For each chromatic component, the sampling rate of horizontal direction and vertical direction is all
It is 2:1, it is possible to say that the sampling rate of coloration is 4:1.
In the present embodiment, SiI8630 chips can also be used format YCbCr 4:4:4 boil down to YCbCr4:2:2, it is real
Existing 1/2 compression.That is, the present embodiment SiI8630 chips can carry out 1/ to 2.0 signals of HDMI that input format is RGB
3DSC compresses, and can also be YcbCr 4 to input format:4:4 2.0 signals of HDMI are converted into YCbCr 4:2:2.It needs
It is bright, 1/3DSC compressions and YcbCr4:4:4 are converted into YCbCr 4:2:2 cannot use simultaneously, this is because SiI8630 cores
It is the operation of bypass inside it, and the data that 1/3DSC compressions are directed to input lattice though there are two types of data compression schemes for piece tool
Formula is RGB, YcbCr 4:4:4 or YCbCr 4:2:0, no YCbCr 4:2:2 formats, so cannot achieve two kinds of compress mode weights
Compound compression.
