This paper presents a 3D (three dimensional) mobile broadcasting service based on depth-image-based rendering (DIBR) technique in terrestrial digital multimedia broadcasting (T-DMB). In designing and developing a 3D visual service based on mobile broadcasting system, we must consider system requirements such as the minimization of additional bit-rates for 3D depth information due to the limitation of transmission channel bandwidth, the assurance of backward compatibility with existing T-DMB, and the maximization of 3D effect while reducing eye fatigue. Therefore, the 3D mobile broadcasting service based on DIBR technique can be one of the solutions to meet such requirements because the allocated bit-rates of depth image with DIBR scheme is less than additional video bit-rates of another 3D format, while keeping 3D quality and guaranteeing backward-compatibility with T-DMB. In this paper, we introduce an implementation of DIBR-based 3D T-DMB system that supports the real-time rendering with good image quality and depth effect at the receiver, verifying that it could be available in the mobile broadcasting. The verification is achieved through objective and subjective evaluation, based on the simulation and implementation of the system. Finally, we will confirm that DIBR-based 3D mobile broadcasting service would be commercialized in near future. © 2009 SPIE-IS&T.
