Even so, they do not achieve a realistic and immersive view of the world since they do not offer important depth cues to the human vision system. Three- dimensional video (3DV) technologies try to fulfill this gap through video representations that enable 3D displays to provide those additional depth cues. A lthough CSV (Conventional Stereoscopic Video) has been the most widely-used 3DV representation, other 3DV representations have emerged during the last years. Examples of those representations include MVV (Multi-view video), 2D+Z (2D plus depth), MVD (Multi-view plus depth), and LDV (Layered-depth Video). Although end-to-end 3DV delivery chains based on those 3DV formats have been studied, the integration of interactive multimedia applications into those 3DV delivery chains has not yet been explored enough. The integration of multimedia applications with 3D media using those new representations has the potential of allowing new rich content, user experiences and business models. In this thesis, two approaches for the integration of multimedia applications into 3DV end-to-end delivery chains are proposed. First, a backward-compatible approach for integrating CSV-based media into 2D-only multimedia languages is discussed. In this proposal, it is possible to add depth information to 2D-only media objects. The proposal consists of extensions to multimedia languages and a process for converting the original multimedia application into its stereoscopic version. It does not require any change on the language player and is ready-to-run in current CSV-based 3DV delivery chains and digital receiver's hardware. Second, extensions to multimedia languages based on layered-depth media are proposed and a software architecture for the graphics composition of multimedia applications using those extensions is presented. As an example, both proposals are implemented and integrated into an end-to-end 3DV delivery chain based on the Brazilian Digital TV System.","author":[{"propositions":["de"],"lastnames":["Albuquerque","Azevedo"],"firstnames":["Roberto","Gerson"],"suffixes":[]}],"year":"2015","bibtex":"@thesis{de_albuquerque_azevedo_supporting_2015,\n\tlocation = {,},\n\ttitle = {Supporting multimedia applications in stereoscopic and depth-based 3D video systems},\n\tabstract = {Two-dimensional video technologies have evolved quickly in the last few years.
