东芝公司研制了内含场存贮器的家用VTR。放静止图象时,不存在时间延迟。减速放像或两倍加速放像时的图象质量良好。也可以接收广播电视的信号以静立图象输出。使转动碰头的装配变得方便容易。场存贮器由标准的动态RAM组成,使用四个64k×4位和两个64k×1位DRAM,用6位的分辩率把复合电视信号作A-D转换。标准频率是彩色载波频率的3倍。
Toshiba has developed a home VTR containing field memory. There is no time delay when placing still images. Good image quality during slow motion playback or twice accelerated playback. Can also receive radio and television signals to the static image output. Makes it easy to turn the assembly. The field memory consists of standard dynamic RAM using four 64kx4 bits and two 64kx1 bit DRAMs for A-D conversion of the composite television signal with 6 bit resolution. The standard frequency is three times the color carrier frequency.
