Abstract

In this invention, it is possible to realize a video signal output apparatus having so called Near Video On Demand function such that, in respective reproducers of a plurality of reproduction blocks within a video reproduction section, with respect to a plurality of divided image sources obtained by dividing an image source into image sources of a plurality of time zones, divided image sources of the same time zone are simultaneously repeatedly reproduced in the state where they are respectively shifted by a predetermined time to carry out switching between a plurality of video signals delivered from the plurality of reproducers by a video select switch to thereby provide successive image sources, without being conscious of time and switching operation of image sources reproduced in accordance with selection of a desired image source by the viewer also with respect to image source of data quantity corresponding to time longer than the memory capacity of each of media of the reproducers.
