Method and apparatus for encoding/decoding motion vectors of multiple reference pictures, and apparatus and method for image encoding/decoding using the same
A motion vector encoding apparatus includes: an optimum motion vector determiner for determining optimum motion vectors for multiple reference pictures with respect to a current motion vector of a current block; a motion vector encoding mode determiner for determining a motion vector encoding mode according to whether a motion vector decoding apparatus can predict the optimum motion vectors for the multiple reference pictures; and a motion vector encoder for generating and encoding motion information on the multiple reference pictures by using the optimum motion vectors for the multiple reference pictures or preset default motion vectors for the multiple reference pictures according to the motion vector encoding mode, and generating motion vector encoded data by encoding the motion vector encoding mode. The motion vector encoding apparatus can more accurately predict a predicted motion vector of the current motion vector for multiple reference pictures, so as to improve the compression efficiency.
