1. A method for estimating motion for scalable video coding, comprising: receiving 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 based on a Left block to the left of the current block, a Top block above the current block and a TopRight block above and to the right of the current block in a current image; and encoding the at least one block as a function of the median MV.
