Motion compensating system using interlace-to-sequential scan conversion with motion and transmission compensation

A motion compensation system in a digital television including an analog-digital converter for converting an interlaced scanning video signal into a digital video signal, said motion compensating system comprising:

• color/brightness signal separating means for separating a first color signal and a first brightness signal from said digital video signal;
• picture motion sensing means for detecting an amount of horizontal transition and temporal motion of a picture from said first brightness signal and an amount of vertical transition of the picture from said digital video signal for enabling comparison and compensation of said amounts of horizontal and vertical transition and temporal motion to obtain a motion signal indicative of motion of a picture;
• and
• mixing means for interpolating the first color signal and the first brightness signal to produce an interpolated color signal and an interpolated brightness signal, and for compensating respectively the interpolated color signal and the first color signal, and the interpolated brightness signal and the first brightness signal in dependence upon said motion signal, each set of color signals and brightness signals being mixed to produce a second color signal and a second brightness signal for the interlaced scanning.
