Slideflow navigation allows the content creator to design full-screen application pages, and specify the order in which they are presented. The user experience is similar to browsing through a PowerPoint slide presentation. While pages can contain selectable hotspots to provide additional content and information related to the currently presented page, navigation between the individual pages is sequential, allowing the content creator to build upon information presented on earlier pages and establish a narrative flow.
Event-based navigation enables the presentation of HbbTV content to be driven by the broadcast programme. The most common example is the presentation of a red button at the start of a TV programme or advert to alert the viewer that additional information is available. While the appearance of the button is usually triggered by MPEG stream events, alternative channels. e.g. web sockets or application pull-requests, can be used as well. Event based navigation is best suited for small information inserts.
