Abstract
Abstract Methods and apparatus for recording and subsequently reproducing video information at a display scan rate record image fields or other video signal quanta on a recording medium at a first relative recording medium velocity and in accordance with a predetermined arithmetic progression. The recorded image fields or other video signal quanta are reproduced at a second relative velocity being higher than the first velocity so that the reproduced video signal quanta are synchronized at the display scan rate. The reproduction of recorded image field or video signal quanta is repeated in the same reproducing operation at the second relative velocity. The repeated reproduction of any recorded image field or other video signal quantum in the same reproducing operation is completed before commencement of the reproduction of any recorded image field or other video signal quantum whose number in the predetermined arithmetic progression occurs more than one term after the number of the particular image field or other video signal quantum. Each occurring image field or other video signal quantum may be recorded by this method or apparatus. On the other hand, skip field techniques may be realized by the methods and apparatus of the subject invention.
