N2  - Scalable High Efficiency Video Coding (SHVC), is the most recent video coding solution mainly designed for network adaptive or device adaptive applications. SHVC follows a layered coding structure with one base layer (BL) and one or several enhancement layers (ELs) which can be unequally protected. However, SHVC is often sensitive to the packet loss in unreliable networks, especially in case of ELs. In this paper, we propose a novel error concealment method for the SHVC EL with an assumption that the BL is well protected. First, we recover the partitioning and resample the motion data from collocated BL frame. Following, we remove outliers of motion field by a motion vector refinement algorithm. Lastly, we conceal loss frame by using motion compensation and deblocking filter. Experiments conducted with a rich set of test sequences and for the spatial-scalable SHVC standard have shown that our proposed method significantly outperforms the relevant error concealment methods, e.g., BL Reconstruction Up-sampling (RU) and BL-SKIP in both subjective and objective quality assessments.
