Abstract: Abstract The video error concealment with data hiding (VECDH) method aims to conceal video errors due to transmission according to the auxiliary data directly extracted from the received video file. It has the property that can well reduce the error propagated between spatially/temporally correlated macro-blocks. It is required that, the embedded information at the sender side should well capture/reflect the video characteristics. Moreover, the retrieved data should be capable of correcting video errors. The existing VECDH algorithms often embed the required information into the corresponding video frames to gain the transparency. However, at the receiver side, the reconstruction process may loss important information, which could result in a seriously distorted video. To improve the concealment performance, we propose an efficient VECDH algorithm based on compressed sensing (CS) in this paper. For the proposed method, the frame features to be embedded in every video frame are generated from the frame residuals CS measurements and scrambled with other frame features as marked data. The marked data is embedded into the corresponding frames by modulating color-triples for its least impacts on the carriers. For the receiver, the extracted data is used to reconstruct residuals to conceal errors. Error positions are located using the set theory. Since the CS has the ability to sample a signal within a lower sampling rate than the Shannon–Nyquist rate, the original signal could be reconstructed very well in theory. This indicates that the proposed method could benefit from the CS, and therefore keep better error concealment behavior. The experimental results show that the PSNR values gain about 10 dB averagely and the proposed scheme in this paper improves the video quality significantly comparing with the exiting VECDH schemes.
