Patent ID: 8463058

Claim:
A method of predicting a motion vector for a current block in a current picture by a moving picture decoding device, the method comprising: obtaining, by the moving picture decoding device, at least one motion vector of a block other than the current block, wherein said other block is associated with at least one reference picture indicated by a reference index for a set of multiple reference pictures; obtaining, by the moving picture decoding device, a first picture order count value of the current picture, wherein the first picture order count value represents a display order of the current picture; obtaining, by the moving picture decoding device, a second picture order count value of the at least one reference picture, wherein the second picture order count value represents a display order of the at least one reference picture; comparing, by the moving picture decoding device, the first picture order count value of the current picture with the second picture order count value of the at least one reference picture predicting, by the moving picture decoding device, the motion vector for the current block using said at least one motion vector, based on the comparison.
