? Note:

? ? ? ? Pixel Rate = Htotal * Vtotal * Frame Rate

????? ? Hblank = Hfront + Hsync + Hback

? ? ? ? Htotal? = Hactive + Hblank

????????H Freq = Frame Rate * Vtotal

? ? ? ? Vblank = Vfront + Vsync + Vback

? ? ? ? Vtotal = Vactive + Vblank

? ? ? ? V Freq = Frame Rate

? ? ? ? ?这里,Htotal的时间单位是一个像素时钟周期,Vtotal的时间单位是一个Htotal的总像素时钟,也就是扫描一行的时间

? ? ? ? Field Rate,这里理解为帧率Frame Rate;

? ? ? ?VIC:Video Information Code or Video Identification Code,用来识别视频的格式;

????????I/P:Interlace or Progressive,隔行或逐行扫描

参考标准:
