Optical disc players are today connectable to the Internet, and may contain local storage capability, e.g. HDD. Additional post-production content can be downloaded and locally stored. It is difficult to include downloaded additional post- production material in menus for keeping a menu always consistent with the actually available data. Ideally, the menu should reflect the available data even if certain content is deleted or replaced with e.g. another version. A ‘linked-list’ approach for menu pages generates a dynamic menu structure. The menu consists of basic menu pages, which are retrieved from the disc, and additional pages that are downloaded together with the additional content. Page ranges may be reserved for e.g. audio, video or subtitles. The linked-list is implemented by an implicit link from each page to the next higher or lower page number.
