    摘要: A BD-ROM stores a video stream and a graphics stream. The video stream represents a moving picture. The graphics stream is used for overlaying one or more menus on the moving picture, and includes interactive control information (ICS) and a plurality of pieces of graphics data (ODSs). The graphics data is used to generate both the menus and an effect for introduction or removal of a menu. The interactive control information includes (i) a reference value (window_id_ref) specifying a window within which each display composition of graphics is rendered for presenting the effect and (ii) information (effect_duration) showing a duration after which a display composition is replaced by a subsequent display composition.
