ABSTRACT:
A video scramble apparatus has a scrambler for scrambling an input video signal, and a video encoder for performing interframe predictive coding of the video signal after scrambling, and the scrambler selects a frame, which is not used as a reference frame for interframe prediction in the video encoder, from the input video signal, and scrambles the frame by pixel replacing in units of slices within a predetermined vertical range or pixel replacing in units of n consecutive macroblocks within a predetermined horizontal range.
