Patent ID: 8731060

Claim:
A video encoding system for encoding consecutive images of a video sequence, the encoding of at least one current image (F n ) being operated with respect to at least one previous image or at least one subsequent image, or both at least one previous image and at least one subsequent image, (F n-1 ) of said video sequence, said encoding system comprising one or more electronic circuits including: an input data reception means for receiving said current image (F n ) to be encoded and a non estimated real motion vector that is representative of an area of said current image that has moved within said current image (F n ); means for dividing said current image (F n ) into macroblocks; a data estimation means for estimating motion vectors depending on the macroblocks of said current image (F n ) and on said at least one previous image or said at least one subsequent image, or both said at least one previous image and said at least one subsequent image, (F n-1 ); a motion compensation means for receiving motion vectors and for providing at least one predicted area; means for allocating said non estimated real motion vector to the macroblocks belonging to said moved area; means for transmitting said non estimated real motion vector directly to said motion compensation means without any estimation of the motion vectors by said data estimation means for said macroblocks belonging to said moved area, and a subtractor means for determining a difference between pixels of the current image (F n ) and the predicted area and for providing a residual error (D n ) corresponding to said determined difference.
