Scalable Stereoscopic Video Coding for Ubiquitous Computing Environments

초록

This paper presents a new stereoscopic video coding approach for heterogeneous consumer devices by exploiting the concept of spatio-temporal scalability. The proposed method uses MPEG standard for coding the left-view sequence and an enhanced compatible coding scheme for predicting the P- and B-types of frames of the right-view sequence. The enhanced compatible coding scheme predicts matching block by interpolating both motion and disparity predicted macroblock. To provide flexible stereo video service, we define both temporally and spatially scalable layers for each eye-view. The experimental results show the efficiency of proposed coding scheme by comparison with already known methods and the advantages of disparity estimation in terms of scalability overhead.
