PDP等离子彩电视频处理电路,主要包括:视频解码、A/D转换、去隔行处理、SCALER(图像缩放)和PDP面板接口电路等部分。1.视频解码电路根据解码的方式不同,视频解码可分为模拟解码和数字解码两大类。(1)模拟解码电路模拟视频解码就是对输入的视频信号先进行Y/C(亮/色)分离,再将色度C信号分离出U(B-Y)和V(R—Y)信号,最后在矩阵电路中与亮度信号Y进行计
PDP plasma TV processing circuit, including: video decoding, A / D conversion, de-interlacing, SCALER (image scaling) and PDP panel interface circuit and other parts. 1. Video decoding circuit Depending on the decoding method, video decoding can be divided into analog decoding and digital decoding two categories. (1) analog decoding circuit Analog video decoding is the first of the input video signal Y / C (light / color) separation, and then separate the color C signal U (BY) and V (R-Y) signal, and finally Matrix circuit and the brightness signal Y meter
