面向移动通信的3DTV 交织编码错误隐藏方法

摘要

Mobile 3DTV is different from traditional 3DTV in video format and coding structure, moreover, it requires low computational complexity due to the power limitation. In this paper, different view interlaced coding and error concealment schemes are proposed for mobile 3DTV. The left and right views are first interlaced followed by the stereo SEI structure used for encoding. If packets are lost during the transmission, different error concealment schemes are selected according to different types of errors. Experimental results show that the proposed method achieves satisfactory error concealment effects with low computational complexity.%　　针对移动通信 Mobile 3DTV 和传统3DTV 视频表示格式与编码结构的差异以及 Mobile 3DTV 低计算复杂度的特点，提出一种面向 Mobile 3DTV 交织编码的立体视频错误隐藏方法。新方法在编码之前先将左右视点进行交织处理，然后按照 Stereo SEI 的编码结构编码传输，在解码端根据像素的不同错误类型有针对地选择相应低计算复杂度的错误隐藏方法恢复丢失信息。实验表明，该方法在解码端得到的恢复效果较好，并且计算复杂度较低。
