代码说明:

应用背景为了实现良好的压缩性能,相关性颜色分量RGB颜色空间转换到去相关的色彩空间首先减少。在基线JPEG,一个RGB图像转化成亮度chrominancc如YCbCr颜色空间。将图像的亮度色度空间的优势的亮度和色度分量非常不相关彼此之间。此外,色度通道包含大量冗余信息可以很容易地被采样不牺牲任何视觉质量对于重建图像。从RGB到YCbCr的转换,是基于以下的数学表达:关键技术应用DCT变换,将图像划分成8´8像素块。如果原始图像的宽度或高度是不能被8整除,编码器必须整除。8´8块进行处理,从左到右,从上到下。和公司;及;及;及;及;及;及;及;及;DCT变换的像素值的空间频率。这些空间频率是非常相关的细节目前在一个图像的水平。高空间频率对应于高层次的细节,而较低频率对应于较低的细节层次。数学定义DCT是:

  • DisplayPort Link training optimization
    说明:  介绍了Displayport规格中lind training的背景研究,设计和实现。(As the requirement for bandwidth continues to increase in the video market, retaining the signal integrity becomes increasingly more difficult. For many of todays commonly used video interfaces, there are devices that can be used to assist in this matter. However, the use of such a device is only partially documented in the DisplayPort specification for the receiving image device, which means that the receiving side of the video link is free to choose its own implementation. This report presents, together with background research and design decisions, a suggestion for such an implementation. This implementation would need to be compatible towards a wide range of possible video Source devices and DisplayPort cables.)
