The method includes obtaining initialization information of a reference picture list for a random access slice, the initialization information representing a reference relation between a plurality of views, initializing the reference picture list for inter-view prediction by appending an inter-view reference index to an initialized reference picture list for temporal prediction based on the view number information and the view identification information, obtaining modification information for the initialized reference picture list, determining an assignment modification value for modifying the inter-view reference index in the initialized reference picture list according to the modification information, and modifying the initialized reference picture list for inter-view prediction using the determined assignment modification value.
