发明名称 Reproducing digital video signals
摘要 <p>In a method and apparatus for reproducing digital video signals, in which every one frame of data of the signals is recorded on n tracks (A1, B1, ....... A10, B10) of a recording medium by an inclined azimuth recording system, the signals are reproduced at varying speed by a rotary head (1) having n heads (HA1, HB1, HA2, HB2) with a varying playback speed S controlled (7) to be equal to a(t.m+/-1)/n, where a is a constant equal to 1 or 2 and m is a constant which is an integer other than 0. Due to this, when a picture corresponding to the digital video signals read out with the varying playback speed S is displayed on a screen, non-continuous lines caused by a temporal difference between neighboring macro-blocks during varying speed reproduction may be rendered less obtrusive so as thereby to improve the picture quality of the varying speed reproduced picture. &lt;MATH&gt;</p>
