Abstract
A video receiver receives a compressed 3D video comprising a base view video and a residual view video from a video transmitter. The video receiver decodes the received base view video and an enhancement view video of the received compressed 3D video into a left view video and a right view video. Base view pictures are generated selectively based on available memory resource. The residual view video is generated by subtracting base view pictures from corresponding enhancement view pictures. The received base view and residual view videos are buffered for video decoding. Pictures in the buffered residual view video are added to corresponding pictures in the buffered base view video for enhancement view decoding. The left view video and/or the right view video are generated from the resulting decoded base view and enhancement view pictures. A motion vector used for a disparity predicted macroblock is applied to adjacent macroblock pre-fetching.
