A STUDY ON THE STEREOSCOPIC CODECS FOR NON-REAL TIME 3DTV SERVICES

摘要

This paper presents a study on the stereoscopic 3D codec for non-real-time 3DTV services. Delivering stereoscopic 3DTV contents via broadcast networks can be based on either real-time or non-real-time scenarios. For a digital television system where its bandwidth is somewhat limited to accommodate the full 3D HD quality video, a complementary enabler is the non-real-time delivery in which 3D video component is downloaded in advance. In the case of ATSC system, MPEG-2, H.264/AVC and any other codec can be used for stereoscopic video based on Non-Real-Time services. In order to put in the best performance, the analysis on the stereoscopic codec, scenarios and preliminary considerations are required. In this paper, the NRT 3D codec scenarios and preliminary considerations are addressed to develop the prerequisites required for the analysis on NRT 3D codec. The experimentation of both independent and inter-view coding are covered to investigate the codec combination for NRT 3D video services based on considerations and scenarios.
