Video display system for wide and standard aspect ratio video signals

摘要

A video display system for displaying a wide screen image having an aspect ratio, such as 5:3, greater than the standard, such as 4:3, aspect ratio of the images represented by conventional television video signals, is arranged for displaying such an image of standard aspect ratio without changing the width of the normal wide aspect raster of the display system. To this end the display system includes a signal processor which, in response to a video signal representative of a standard aspect ratio image, produces, for driving the wide aspect ratio display, a processed video signal the line periods of which each include not only the line synchronizing interval and active video interval but also a delay interval ('PAUSE') the effect of which is to determine the position of the displayed standard aspect ratio image within the width of the wide aspect ratio raster.
