FIELD: information technology.
SUBSTANCE: disclosed is an image decoding method comprising steps of parsing network abstraction layer (NAL) units of a base view (S200); decoding an image of the base view (S202); parsing multiview video coding (MVC) extension parameters of a non-base view (S204); searching whether or not prefix NAL units for a base view are present (S205); either calculating MVC extension parameters for the base view when no prefix NAL units are present (S206) or parsing the MVC extension parameters of the base view when prefix NAL units for the base view are present (S207); and decoding the non-base view using the MVC extension parameters of the base view and the MVC extension parameters of the non-base view (S210).
EFFECT: providing multiview video coding methods of multiview video decoding methods, even when prefix NAL units are not used.
