Claim:
1. A method for reframing an original video signal, followed by an encoding of the reframed video signal, the method comprising: computing a saliency map for a current picture of said original video signal, said saliency map representing a user attention map; providing a macroblock coding efficiency cost map for said current picture of said original video signal; selecting a candidate reframing window size and position within said current picture of said original video signal; using in combination said saliency map and said macroblock coding efficiency cost map for determining in said original video signal a different position and/or size of the reframing window, for which different position and/or size the coding cost for said reframed video signal are smaller than the coding cost for said candidate reframing window size and position; encoding said corresponding reframed video signal.
