高分解力S-VHS录象机日本胜利公司试制成功一种新格式高分解力S-VHS录象机。该机的水平分解力430线,换成带宽约为5.5兆赫(每兆赫约80线)。这个数值比通常广播(NTSC制)信号的330线高。现有的VHS录象机为230-240线。该机可录放VHS方式,但用S-VHS方式记录的磁带,不能在现有的VHS机重放。该机的带盒形状和现有的同样。但磁带的磁性材料不同。磁带的记录时间也同样,一盒两小时磁带(相当于T-120产品),用标准方式记录时为2小时,用三倍方式记录时为6小时。该机的磁头,走带系统等机构,基本上与现有的VHS机相同。美国开始试播高清晰度电视美国于87年1月7日在华盛顿开始试播高清晰度
High resolution S-VHS VCR Japan victory company trial success of a new format high resolution S-VHS video recorder. The aircraft’s horizontal resolution of 430 lines, with a bandwidth of about 5.5 MHz (about 80 lines per megahertz). This value is higher than the 330 lines of the normal broadcast (NTSC) signal. The existing VHS video recorder is 230-240 lines. This machine can record VHS mode, but the tape recorded by S-VHS mode can not be replayed on the existing VHS machine. The machine’s tape box shape and the same as the existing. However, the magnetic material of the magnetic tape is different. The tape recording time is also the same, a box of two hours of tape (equivalent to T-120 products), using standard recording time of 2 hours, triple recording time of 6 hours. The machine heads, tape systems and other institutions, basically the same with the existing VHS machine. The United States began piloting high-definition television The United States began pilot broadcast high definition on January 7, 1987 in Washington
