Patent Images

1. A method of encoding a sequence of digital images into a bitstream, at least one block of an image being encoded by inter prediction with respect to a reference image block, comprising generating a set of motion vector predictors for a block to encode of a current frame, the set of motion vector predictors being permitted to include at least one spatial motion vector predictor and no more than one temporal motion vector predictor, the generating comprising selecting as said temporal motion vector predictor the motion vector at a predetermined position in the vicinity of a bottom right position of an area of the reference frame collocated with said block to encode of the current frame, and in a block of the reference frame neighboring the collocated area;

  • selecting a motion vector predictor from the generated set as a motion vector predictor for encoding a motion vector associated with the block to encode; and

    encoding in the bitstream information identifying the selected motion vector predictor.
