Method for coding vector refinement for using vectors of base layer picturs and decoding method using the vector refinement

The present invention, encoding the vector micro-information (refinement) and using the coded vector fine information accordingly relates to a method for decoding video data, the motion vector of the co-located corresponding block included in the bit stream of the base layer and an enhanced motion-scaling a percentage of the picture size of the base layer compared to the picture size of the de-layer vector, and the corresponding blocks of the frame with the same time that, with the enhancement of the image block that is included in a frame of de-layer motion vector information on whether the time difference is recorded by selecting a value from among values ​​that are respectively assigned to the eight pels (pel) surrounding the support point of the scaled motion vectors as vector fine information of the image block .
