3D data service over Terrestrial-Digital Multimedia Broadcasting (T-DMB) is very attractive because the single user environment of T-DMB is suitable to glassless 3D viewing. However, the bit budget for transmission of additional 3D data over T-DMB is very limited with 32Kbps through data service channel. To overcome this limited condition, Depth-Image-Based-Rendering (DIBR) can be applied, because corresponding depth sequence is only additionally needed to current TDMB and this can be compressed effectively. Therefore, in this paper, we evaluate 3D data service based on DIBR over T-DMB. Evaluation mainly consists of two experiments. One is to evaluate the coding efficiency of depth sequences and the other is to measure the subjective quality and percived depth of auto-stereosopic image generated by DIBR with coded depth sequence. Therefore, we evaluate the possibility of transmitted depth image through data service channel that transmission rate is 32Kbps. Evaluation results show that DIBR can efficiently be utilized for 3D data service over T-DMB. However, it is also shown that the development of some techniques such as the depth preprocessing is required for the improvement of image quality.
