家园 有200k的录像带?

有200k的录像带?

数字压缩格式问世前,一秒钟影像得多大

传统磁带刻成vcd或dvd,或者仅仅进入非线编系统转存很正常,不是说传统录像带是数字格式

“That was the plan and that was what was done. In 1981 and 1982, we pulled out another 30,000. We then had Landsat in dire need of tapes in the network and we had the start of the shuttle program. Those tapes were pulled out and our records show that they were never returned”

这又如何解释好?

反方这么多,相关新闻怎么解释也不如毁尸灭迹合理
