Decoding and up-sampling optimization for asymmetric coding of mobile 3DTV

Asymmetric stereoscopic video coding can save the bitrate and maintain the overall visual quality of three dimensional perception. But for mobile three-dimensional television, the original full resolution restoring is complex for the decoder. In this paper, a decoding and up-sampling optimization scheme for asymmetric stereoscopic video coding is proposed, in which macroblocks encoded with SKIP mode are checked so as to reconstruct such macroblocks by directly copying from the corresponding full resolution reference frames, i.e., up-sampling with 6 taps filter is omitted for these macroblocks. The experimental results show that the proposed scheme is able to reduce the complexity of restoring the original full resolution of the down-sampled right-view images, while maintain high video quality.
