Video signal processing apparatus for a wide-aspect television

Claim 1

A video signal processing apparatus for a wide-aspect television for producing a wide-aspect display signal by processing a first composite video signal outputted from a video switching unit, said video signal processing apparatus comprising: analog/digital (A/D) converter for converting to a first digitized composite video signal, said first composite video signal generated from said video switching unit; a timing pulse generator for generating a first, a second and a third timing pulses, wherein a frequency of said second timing pulse is higher by a certain ratio with respect to a frequency of said first timing pulse; a multiplexer for inputting said first, second, and third timing pulses and for outputting said first timing pulse or said second timing pulse in accordance with an input of said third timing pulse; a serial video processor for inputting said first digitized composite video signal from said A/D converter in accordance with said first timing pulse from said multiplexer and for outputting a second digitized composite video signal in accordance with an input of said first timing pulse or said second timing pulse from said multiplexer; and a digital/analog (D/A) converter for converting to a second composite video signal, said second digitized composite video signal outputted from said serial video processor.
