摘要:
A video signal recording/reproducing apparatus which records pictures by compressing the video signal in multiple field units and reproduces an signal by the expansion process, and which continuously and repeatedly outputs each field of the reproduced television signal on the screen by use of a field detecting unit which operates to ensure that a reciprocal of a multiplication index of a desired reproducing speed is selected as a number of continuous reproductions of one field and also by use of a change-over unit for changing over the reproduced signal in field units.
