    • In novel television transmission systems like D2-MAC, for example, the signal quality is improved with regard to bandwidth and cross-talk. Some of this signal quality is lost when such a signal is recorded on an ordinary video recorder. The purpose is to construct a video recorder in such a way that high-quality recordings of such signals can be obtained without losing the quality parameters of the signal again thereby. The colour difference signals (R-Y, B-Y) are recorded line-sequentially by the frequency modulation of a carrier (Ft) with second magnetic heads (K2) with a wider gap in a deeper-lying layer (S2) of the magnetic tape (T). Especially for an S-VHS video recorder for recording D2/MAC signals.
    • 在诸如D2-MAC的新电视传输方法中,从带宽和串扰的角度来看,信号质量得到改善。 当利用现有类型的视频记录器记录这样的信号时,该信号的质量部分地再次丢失。本发明的目的是开发一种允许这些信号的良好记录的视频记录器。 而不会由于记录而再次丢失信号质量参数。 色差信号(RY,BY)通过载波(Ft)的FM调制通过具有更大间隙宽度的第二系列磁头(K2)以逐行方式逐行记录 磁带(T)的深(S2)。 特别适用于记录D2-MAC的S-VHS VCR。

    • System for recording and playing back video signals. The incoming video signal is bandwidth compressed by a circuit (16, 114) which chops each line of the video signal and blanks out alternate pixels. Alternate lines are treated differently so that on play back the blanked-out pixels of one line can be replaced by the retained pixels of the next line. The chopped and blanked lines are sequentially distributed across a stack of static heads. On playback there is continuous output from reading heads equal in number to the recording heads and the signals from the reading heads are sampled by a switch (20, 120) so as to reconstitute the chopped lines. The output of this switch is fed to a 1H delay so that a single complete line can be generated from the delayed line and the next line read.
    • 用于录制和播放视频信号的系统。 输入的视频信号被电路(16,114)带宽压缩,该电路斩波视频信号的每一行并将交替的像素空白。 替代线被不同地对待,使得在回放时,一行的消隐像素可被替换为下一行的保留像素。 切碎的和空白的线顺序地分布在一堆静电头上。 在播放时,从与记录头数量相等的读取头连续输出,并且通过开关(20,120)对来自读取头的信号进行采样,以便重构切碎的线。 该开关的输出被馈送到1H延迟,使得可以从延迟线和下一行读取生成单个完整线。
