- Abstract
- In recent years, 3D consumer markets such as movies, broadcasting contents, and consumer electronics have grown large enough so that most of the newly introduced digital TVs are equipped with 3D capability, and the consumers’ demand on 3D broadcasting has grown with the market growth. Many broadcasting standardization organizations such as TTA, ATSC, DVB, SCTE, etc., have been working on standardization of 3D broadcasting service systems, however, they have found out that the terrestrial 3DTV service has problems such as quality degradation due to the bandwidth limitation of the terrestrial broadcasting channels and the backward compatibility with the legacy DTV system. To resolve such issues, hybrid 3DTV system that integrates terrestrial broadcasting channel and IP network is proposed. The proposed hybrid 3DTV system transmits the base view of 3D content via broadcasting channel and transmits the additional view via broadband channel. The main issue with the hybrid 3DTV service is synchronization of views that are coded with different codecs and transmitted via different transmission system. In this paper, metadata stream based synchronization method that is independent of media codec and channel is proposed. Experiments have shown that the proposed method provide quality preserved 3DTV services while maintaining backward compatibility with the legacy DTV system.
