日本胜利公司最近研制成的一种新型数字式录像技术,可比传统的VHS录像方式存储更多的图像和声音信息。一盘录像带可录下49小时的节目。这种被称作“D—VHS“的技术还有一个特点,就是可再生由普通录像机按模拟方式录下的节目。 这种“D—VHS”技术可利用传统S—VHS式的录像带,通过先进的压缩和密码化技术加工数字式资料,将加工后的资料记录在磁带上。与传统的模拟方式相比,图像的精度大大提高。该技术可将2个小时的电影压缩成几分钟的录像,
Victory Japan recently developed a new type of digital video recording technology, than the traditional VHS video storage more images and sound information. A tape can record 49 hours of programming. Another feature of this technology, known as ”D-VHS“, is the reproduction of programs recorded by analog video recorders in common video recorders. This ”D-VHS" technology utilizes traditional S-VHS video tapes to process digital data using advanced compression and encryption technology to record the processed data on tape. Compared with the traditional simulation method, the accuracy of the image is greatly improved. The technology can be 2 hours of the movie compressed into minutes of video,
