Abstract: A system for transferring video data includes a difference detector for detecting the difference between a current field information and the preceding field information. The preceding information is obtained from an entered interlaced video signal. An interpolator generates current display frame information in response to an interpolation based upon the current filed information with regard to an area of the video signal in which there is a difference value between successive fields that exceeds a predetermined threshold value. The interframe difference between the current display frame information and preceding display frame information is detected by the difference detector. Only the interframe difference is transferred over a system bus to enable a frame display to be presented on non-interlacing display device.
