2 TDA9178 introduction
TDA9178 is a analog signal processor with standard YUV input and output
interface .It provid three main process function: luminance vector, color
vector and spectrum process. It can finish comprehensive picture improving
function independently. The characteristics of the TDA9178 are below:
 Luminance Transient Improvement (LTI), Colour Transient
improvement (CTI)
 Variable gamma control
