ABSTRACT:
A processing circuit converts a 16:9 aspect ratio video signal into a 4:3 video signal and includes a time division multiplexer that multiplexes the two video signals and a selector that selects one of the multiplexed signal for display. A mark is added to identify the range in which the 4:3 aspect ratio video signal is displayed relative to the 16:9 aspect ratio video signal.
