Patent ID: 8259805

Claim:
A method for generating coded picture data which are encoded using motion estimation and motion compensation, said method comprising the steps: in case of coding a current pixel block or macroblock of a current picture in a temporally predictive mode, estimating according to predetermined rules related motion information using reconstructed picture information from at least two reference pictures which do not include said current picture and which are temporally prior to said current picture; performing said motion compensation using that estimated motion information for said current pixel block or macroblock and corresponding picture information from at least one of said reference pictures, whereby, in said coded picture data, for said current pixel block or macroblock or for said current picture, motion processing information is included that indicates the corresponding type of coding, and whereby, if for decoding in a decoder-located motion estimation according to said predetermined rules is to be performed using reconstructed picture information from said at least two reference pictures, no motion vector data but motion vector flag data, signaling that for said current pixel block or macroblock or for said current picture said decoder-located motion estimation is to be carried out, are included in said coded picture data.
