1. A method, comprising: receiving, by a computing device including a processor, at least one block of a plurality of blocks of a sequence of images; based on the at least one block, determining a median Motion Vector (MV) for a current block in a current image, based on a Left block leftward of the current block, a Top block above the current block and a TopRight block above and rightward of the current block; determining a Temporal MV representing an estimated MV for forward prediction, the determining the Temporal MV including summing up backward prediction and reversed forward prediction MVs of a frame; and encoding the at least one block as a function of the median MV and the Temporal MV.
