ab: Summary: Advances in display and camera technology enable new applications
    for three-dimensional (3D) scene communication, such as 3DTV. 3D
    Multi-view video contains a large amount of inter-view statistical
    dependencies, since all cameras capture the same scene from different
    viewpoints. Due to the vast raw bit rate, multi-view video data are
    expected to consume a large portion of available bandwidth. Therefore,
    an efficient compression techniques are the key for 3D scene
    communication. Error concealment techniques have the advantage of
    improving the received video quality without encoder modifications or
    transmission rate changes. To improve the quality of reconstructed 3D
    video, we propose different algorithms to conceal the erroneous and
    lost blocks of intra and inter coded frames exploiting the temporal,
    spatial and inter-view correlation between frames and views. There is a
    hybrid of space domain error concealment (SDEC) and time domain error
    concealment (TDEC) introduced for intra-frames losses. Three modes are
    discussed for inter-frames as well, which are time domain error
    concealment (TDEC), inter-view domain error concealment (IVDEC) and
    joint time and inter-view domain error concealment (TIVDEC).
