A method and apparatus for providing spatial scalable compression using adaptive content filtering of a video stream is disclosed. The video stream is downsampled to reduce the resolution of the video stream. The downsampled video stream is encoded to produce a base stream. The base stream is decoded and upconverted to produce a reconstructed video stream. The reconstructed video stream is subtracted from the video stream to produce a residual stream. The resulting residual stream is encoded in an enhancement encoder and outputs an enhancement stream. The residual signal in selected frames is muted in the enhancement encoder while the motion information in the frame is maintained.
