METHOD FOR ENCODING AND DECODING IMAGES USING PLURALITY OF REFERENCE IMAGES AND DEVICE USING METHOD

摘要

Disclosed are a method for encoding and decoding images using a plurality of reference images and a device using the method. The decoding method comprises the steps of: decoding predictive direction information; and decoding reference picture index information on the basis of said predictive direction information. Thus, the invention can increase an encoding efficiency by reducing the number of reference picture indexes.
