Apparatus and method for converting video signal in scanning line order

Abstract

An apparatus and a method for converting a video signal in the scanning line order. The video signal conversion apparatus comprises a video signal converter including an address control circuit for performing an address control operation in response to a synchronous signal and a first clock signal, a luminance signal memory unit for storing and outputting first to fourth luminance signal components of the video data under the control of the address control circuit, a color signal memory unit for storing and outputting first and second color signal components of the video data under the control of the address control circuit, a multiplexing circuit for multiplexing the first to fourth luminance signal components outputted from the luminance signal memory unit, an interpolator for delaying the first and second color signal components outputted from the color signal memory unit for a predetermined time period, first and second D flip-flops for buffering fifth and sixth luminance signal components outputted from the multiplexing circuit, respectively, and a digital interface unit for interfacing the fifth and sixth luminance signal components buffered respectively by the first and second D flip-flops with the first and second color signal components delayed by the interpolator in response to a second clock signal.
