ABSTRACT:
A compressed video system and method enhances the visual perception of motion for frame rates below 24 frames per second by intentionally introducing a motion smearing for the moving parts of displayed images. The system uses a frame or field buffer between the decompressor and A to D converter that averages the combination of the current frame or field digital video signal values and a progression of decreasing values of previous frame or field elements. Better (e.g. less jerky) moving images with reduced noise generation can be achieved with lower bit rates or bandwidth than with prior systems.
