可伸缩3DTV视频编解码器研究

In order to support the 3DTV service through the existing 2DTV infrastructure, a 3D video frame-compatible solution is proposed. In this solution, the left and right views are down sampled and multiplexed by a side-by-side/top-bottom manner. However, this solution reduces the resolution of the original content. The decoded compatible frame should be separate to left view subframe and right view subframe as half-resolution frames and then the letf view subframe and the right view subframe are interpolated respectively to recover the 3D video. The future 3DTV market is also interested in a scalable solution that would provide the output compatibility of 3D half resolution and 3D full resolution images. In this paper, an SVC based 3D scalable video codec is proposed. It takes advantage of the side-by-side compatible frames as the input of the SVC codec. If only the base layer is decoded from the scalable codestream, several classical interpolation methods are used to recover the 3D video. If the entier codestream is decoded, re-interleaving is used to recover the full resolution 3D video. Experimental results show the feasibility of this scheme.
