홈페이지논문 초록 (Abstract)
Non-real-time delivery of stereoscopic video has been considered as a service scenario for 3DTV to overcome the limited bandwidth in the terrestrial digital television system. A hybrid codec combining MP EG-2 and H.264/AVC has been suggested for the compression of stereoscop ic video for 3DTV. In this paper, we propose a stereoscopic video cod ing scheme using adaptive pre-/post-filters (APPF) to improve the qual ity of 3D video while retaining compatibility with legacy video coding standards. The APPF are applied adaptively to blocks of various si zes determined by the macroblock coding mode and reference frame index . Experiment results show that the proposed method achieves up to 24 .86% bit rate savings relative to a hybrid codec of MPEG-2 and H.264/AV C including the inter-view prediction.
