面对全数码化影音系统的发展趋势,Hi-8的创始人索尼公司意识到风行一时的Hi-8摄像机正逐渐落伍,于是开发了新的数字8mm摄像机,这种新型摄像格式称为Digital 8,简称D8。 D8机针对Hi-8的不足进行了改进,其摄像带体积比Hi-8更小,使整机体积也相应缩小。更重要的是,D8机是以数码方式纪录,无论信噪比或是解析度都比记录模拟信号的Hi-8好很多。数码记录的好处是以数码存放影像,不像传统模拟录像机,存放久了或重放多次后会因磨损而使画质降低,D8带即使
Faced with the development trend of all-digital audio-visual system, Hi-8 founder Sony realized the popular Hi-8 camera is gradually outdated, so the development of a new digital 8mm camera, this new camera format called Digital 8 , Referred to as D8. D8 machine for Hi-8 deficiencies have been improved, the smaller the volume of the camera than the Hi-8, so that the whole volume is also reduced accordingly. More importantly, the D8 is digitally recorded, no matter the signal-to-noise ratio or resolution is much better than the Hi-8 recording the analog signal. The benefits of digital recording digital storage images, unlike traditional analog video recorders, stored for a long time or repeated playback due to wear and tear down the picture quality, D8 with even
