在过去的两年中,DVD播放机的性能正在逐步地走上一个较高的水平。除了少数几种入门级的型号外,所有隔行扫描的DVD播放机都能播放出从主观感觉上都相当不错的画面,细节丰富,色彩自然,噪声也较低。你能看得出来的一些差别也是由于视频输出设计及画面比例变换方面的一些差异所造成的。(例如,Sony公司的播放机中采用的“4-tap”算法使画面就比其它算法看上去柔和一些)。 In the past two years, DVD player performance is gradually taking a higher level. With the exception of a few entry-level models, all interlaced DVD players play subjectively good pictures with rich detail, natural colors and low noise levels. Some of the differences you can see are also caused by some differences in video output design and aspect ratio conversion. (For example, the “4-tap” algorithm used in Sony’s players makes the picture softer than other algorithms).
