- Abstract
- In this paper, we introduce a video coding system for the stereoscopic 3DTV service with backward compatibility to the existing ATSC terrestrial HDTV service.In the current ATSC HDTV service, MPEG-2 Video standard is used for video compression with the maximum video bit-rate of approximately 18Mbps per channel. For the backward compatibility to the existing HDTV receivers, the base view (e.g., left view) stream shall be compatible to the existing MPEG-2 video standard. Moreover, the bit budget for both of the base view and the additional view (e.g., right view) streams shall not exceed the 18Mbps constraint. To minimize the quality loss in the base (left) view, we need to minimize the additional (right) view bit-rate as much as possible. Thus, we used MPEG-4 AVC and HEVC, which are more efficient than MPEG-2 Video, as candidate codecs for the additional view video. In the experiment, we compared the coding efficiency of AVC and HEVC, and then evaluated the feasibility of the two 3DTV video coding schemes: MPEG-2+AVC and MPEG-2+HEVC. Since the HEVC standardization are expected to be finished in year 2012, the EVC, which is the ETRI's preliminary test codec for HEVC, was used for HEVC coding instead. We showed that the EVC could give better performance than AVC with approximately 30% bit-rate reduction and that the MPEG-2+HEVC are feasible for the terrestrial 3DTV with the subjective quality similar to the original HDTV service.
