ABSTRACT:
Apparatus which when implemented with a television video synchronizer permits the operator to position the synchronized picture at any desired location of the television raster including off the screen. A typical synchronizer includes a memory address generator for providing addresses to the memory for each active picture sample following sync timing and the video signals are stored in a predetermined nonvarying location in such a way that reading the stored video out of the memory reproduces the video signal. The positioning by the apparatus is achieved by modifying the storage addresses so that the relationship between sync timing and picture timing is changed.
