S-video端子(简称S端子)与传统的AV端子不同,它采用了全新的Y/C(亮度/色度)分离技术,信号不需要经过复杂的调制——解调,因而Y/C信号之间的串扰大大减小,可以明显地改善图像质量。笔者的长虹VD8000型VCD机没有S端子,播放VCD碟片,图像质量一般(因VCD采用MPEG1解码方式清晰度只有250线左右),因此考虑加装S输出端子,以在一定程度上有利于提高图像质量,并使彩电上的S输入端子得到充分利用。其它不带S端子的VCD机也可参照改装。 VD-8000机采用CL484解码芯片、SAA7185数字视频编码和视频D/A转换芯片。SAA7185系飞利浦
Unlike conventional AV terminals, the S-video terminal (referred to as the S terminal) uses a new Y / C (luminance / chrominance) separation technique that does not require complicated modulation-demodulation of the signal, so the Y / C signal The crosstalk between the greatly reduced, can significantly improve the image quality. The author of Changhong VD8000 VCD player without S-Video, VCD player, image quality in general (due to VCD using MPEG1 decoder only about 250 lines resolution), so consider the installation of S output terminals, to a certain extent, help to improve Image quality, and to make full use of the S input terminal on the color TV. Other without S terminal VCD player can also refer to modified. VD-8000 machine using CL484 decoder chip, SAA7185 digital video encoding and video D / A converter chip. SAA7185 is Philips
