A hybrid error concealment scheme for H.264/AVC that uses the concept of watermarking, Overlapping Boundary Match-ing Algorithm (OBMA) and Projection Onto Convex Sets (POCS) is proposed in this paper. The advantage of this scheme is that, watermarking is performed during the en-coding process itself. The specific features of both intra coded and inter coded frames are exploited for this purpose. The proposed method chooses watermarking or OBMA or POCS or a combination of them selectively for error concealment which minimizes computational complexity. Simulations are performed to show that the proposed method works well with those videos which have abruptly moving blocks.
