5.PAL编码器/PAL解码器(1)PAL编码器:PAL制彩色全电视信号由色度信号(F)、亮度信号(Y)、行、场复合消隐信号(A)、行、场复合同步信号(S)以及色同步信号等组成,缩写成FBAS。编码器就是用来实现FBAS形成的电子设备。其方框如图2所示。编码器输入的三基色信号由彩色摄像机送来;编 5.PAL Encoder / PAL Decoder (1) PAL Encoder: PAL system full color television signal consists of chroma signal (F), brightness signal (Y), line and field composite blanking signal Composite sync signal (S) and color burst signal, abbreviated as FBAS. Encoder is used to achieve the formation of FBAS electronic equipment. Its box is shown in Figure 2. Encoder input trichromatic signal sent by the color camera;
