25 DVD 影碟比 VCD 好在哪里?能否用普通电视机看?答:可以概括为一句话:DVD 影碟比 VCD 的图像、声音质量好,功能多,而且还不是差一星半点。例如 DVD 的一幅图像是由横向720个像素、纵向576像素构成(PAL 制),相当电视广播的质量。而 VCD 的图像则由横向352个像素、纵向288个像素构成,只相当 VHS 家用录像带的水平。换句话说 DVD的图像清晰度可到500线以上,而 VCD 只有260线左右。再加上内部信号处理最高数码率的限制,观看 DVD 和 VCD 图像的主观感觉差别是很大的。无论是画面的清晰、层次的丰
25 DVD video discs are better than VCD? Can I watch with ordinary TV? A: Can be summed up as a sentence: DVD video discs than VCD images, sound quality, function and more, and not the worst one and a half. For example, an image of a DVD is composed of 720 pixels in the horizontal direction and 576 pixels in the longitudinal direction (PAL system), which is equivalent to the quality of the television broadcasting. The VCD image by the horizontal 352 pixels, vertical 288 pixels, only VHS home video tape level. In other words DVD image resolution can be more than 500 lines, while the VCD only about 260 lines. Coupled with the internal digital signal processing limit the maximum rate of viewing DVD and VCD images subjective difference is great. Whether the picture is clear, the level of abundance
