Abstract To deal with the problem of entire B-frame loss in stereoscopic video coding with Hierarchical B Pictures (HBP) predict structure, this paper analyzes the motion vector correlations in the frames of adjacent views in a double-view sequence, and proposes a hierarchical Error Concealment (EC) algorithm. This algorithm possesses two features distinct from the popular methods. First, the algorithm applies hierarchical concealment technique, which uses different error concealment methods according to the important level of the B frames. Second, the macroblock’s motion vector correlations in adjacent-view sequence are taken into account. Experiments show that the proposed method outperforms state-of-the-art EC algorithms used in the H.264/MVC for entire frame loss.
