<p>A method of encoding and compressing a video sequence, for transmission across a video channel, includes converting the original sequence of frames (O) to a compressed sequence (C) which includes intra-frames, predicted frames and interpolated frames. A sequence of residual images (R) is then determined by subtracting the original frames from the compressed frames. Finally, a spatial/temporal transform is applied to the residual image sequence, the output of which is transmitted across the video channel from the video encoder to a video decoder. A similar approach, using a temporal transform on the residuals, may be applied to audio compression.</p> |
