FIELD: physics.
SUBSTANCE: method is performed by determining a co-located unit relative to the current unit of the current image from the number of image units which is restored to the current image, checking whether an access to the first reference list from the number of reference lists of the co-located unit is made, and selectively checking whether an access to the second reference list is made, determining one co-located reference list from the first reference list and the second reference list, determining the reference unit relative to the current unit by using the motion information of the co-located reference list and performing a mutual forecasting for the current unit by using a specific reference unit.
EFFECT: providing a mutual forecasting for determining a reference image using a co-located image.
