东芝公司第一台DVD播放机的问世对于逐行扫描技术而言是一个极大的支持。同时,该技术还赢得了数字化电视的响应。到现在为止,DVD播放机仍旧要在把影碟上的480线逐行扫描信号(480p)进行处理后才能得到在一般传统电视上放映的隔行NTSC图象。这种信号处理方式可能会造成看得见的光点闪烁和扫描行。东芝公司似乎并未明确表示要在当今电视及电脑制造商之间的有关格式的争论上支持哪一方。它折衷宣布打算同时支持数字电视和未来的顶置盒上存在的两种格式。东芝北美产品计划部主管Craig Eggers说:“这表明了我们这个部门所具有的灵活性——虽然不太清楚顶置盒将采用哪种格式,但是我们显然都有所准备。”此次的DVD及电视样机均运用了东芝称之为ColorStream PRO的逐行扫描元件的影象输入输出技术。该技术可以对DVD盘片上的初始逐行扫描信号提供保护并直接转换。据东芝说,此款SD7108型的DVD播放机是首款适用于480p标准图象效果数字电视的产品。新的DVD播放机将与27MHz加速数码滤波器捆绑,它所拥有的D/A四倍速转换器从指标上看将更为精确。三种配有
The advent of Toshiba’s first DVD player is a tremendous support for progressive scanning technology. At the same time, the technology has also won the response of digital television. Until now, DVD players still had to process the 480-line progressive scan signal (480p) on a video disc to obtain an interlaced NTSC picture on a typical conventional television. This type of signal processing can cause visible blinking and scanning lines. Toshiba does not seem to be exactly what party to support on the format controversy between today’s television and computer makers. It is a compromise that announces intent to support both the digital TV and the two formats present on the future set-top box. Craig Eggers, director of North American product planning at Toshiba, said: “This shows the flexibility of our department - although it’s not clear what format the boxes will be in, we are clearly prepared.” This DVD And TV prototypes all use the image input and output technology that Toshiba calls the progressive scan element of ColorStream PRO. The technology provides protection and direct conversion of initial progressive signals on DVD discs. According to Toshiba, this SD7108-based DVD player is the first product for 480p standard-definition digital TVs. The new DVD player will be bundled with a 27MHz Acceleration Digital Filter, and the D / A quad-speed converter it holds will be more accurate in terms of metrics. Three with
