An example of stereoscopic data service contents: the interlaced images are the stereoscopic contents
Source publication
This paper presents a stereoscopic contents authoring system that covers the creation and editing of stereoscopic multimedia contents for the 3D DMB (Digital Multimedia Broadcasting) data services. The main concept of 3D DMB data service is that, instead of full 3D video, partial stereoscopic objects (stereoscopic JPEG, PNG and MNG) are stereoscopi...

... with an enhanced viewing experience by rendering stereoscopic objects on a conventional 2D video with a relatively low bitrate. Technically, 3D objects, related to the 2D video program, with file formats of JPG, PNG, and MNG (Multiple Network Graphics) could be highlighted on plain 2D background video with the partial 3D effect as depicted in Fig. 2. This approach brings the advantage of saving amount of capacity because we have only to deliver the partial 3D data instead of the delivery of full enhancement layer video. When this 3D object data stream is to be transmitted via the 2D video service channel, it is possible enough to allocate just 32kbps data capacity. Considering the ...

... stated in above, this block is to support the editing of 2D video sequence the part of background video for the 3D data service as illustrated in Fig. 2. Unlike the normal monoscopic 2D video service, this 2D video sequence is necessary to be edited sometimes in order to be harmonized well with the associated 3D objects. According to use case of our 3D DMB data service addressed in section 3, the 3D program segment is BIFS service interval which is composed of 2D background video and ...

This chapter introduces a 3D DMB player which can provide realistic 3D services to consumers in terrestrial-digital multimedia broadcasting (T-DMB) systems. This chapter also provides a parameter approximation method which can create auto-stereoscopic images reliably in the 3D DMB player. Since the bit-budget for the transmission of additional data stream is strictly limited in current T-DMB systems, depth-image-based rendering (DIBR) techniques have been studied to provide 3D services in mobile devices. In order to create the auto-stereoscopic images reliably in the 3D DMB player, exact parameters such as convergence distance, scale factor, and far/near clipping plane should be given in contents. However, some contents contain unknown or inappropriate parameter values in a real environment. This makes it extremely difficult to create auto-stereoscopic images and provide consumers with reliable 3D services. Therefore, we explain how to approximate the rendering parameters by taking mobile display size into consideration. Experimental results show that the parameter approximation method can create auto-stereoscopic images reliably in the 3D DMB player.
