A portion of an image, belonging to a current encoding unit, is encoded by motion compensation with respect to a reference image portion indicated by an item of motion information. A motion information predictor is selected from among a set of motion information predictors and the item of motion information is encoded with respect to said motion information predictor. The set of motion information predictors used is permitted to include at least one temporal motion information predictor associated with an image portion of a previous image of said sequence but is not permitted to include any spatial motion information predictor that is unobtainable from encoded data of said current encoding unit, for example a spatial motion information predictor that was itself encoded with respect to a temporal motion information predictor.
A method of encoding a sequence of digital images into a bitstream, wherein at least one portion of an image in the sequence is encoded by motion compensation, the method comprising:
A method of decoding a bitstream comprising an encoded sequence of digital images, at least one portion of an image in the encoded sequence being encoded by motion compensation, the method comprising:
A device for encoding a sequence of digital images into a bitstream, wherein at least one portion of an image in the sequence is encoded by motion compensation, the device comprising:
A device for decoding a bitstream comprising an encoded sequence of digital images, at least one portion of an image in the encoded sequence being encoded by motion compensation, the device comprising:
A non-transitory computer-readable medium storing a program which, when executed by a computer, causes the computer to encode a sequence of digital images into a bitstream, wherein at least one portion of an image in the sequence is encoded by motion compensation, the program comprising:
A non-transitory computer-readable medium storing a program which, when executed by a computer, causes the computer to decode a bitstream comprising an encoded sequence of digital images, at least one portion of an image in the encoded sequence being encoded by motion compensation, the program comprising:
