ABSTRACT:
A television system including a memory for storing subsampled fields in different sectors corresponding to respective small pictures of a rectangular multi-picture array, includes apparatus for expanding the subsampled fields, preferably to full-screen size, as they are read-out of the memory. When the stored sub-sampled fields correspond to different fields of the same video signal, the arrangement provides for a re-animated version of multi-picture array in a so-called "instant replay" mode of operation.
