Abstract

One way to protect the copyright of the video content is inserting invisible information - the watermark in the video content. The extraction of the embedded watermark is especially difficult in wireless networks, which are a subject to packet drops. Although multimedia applications are tolerant to packet losses, it cannot be said for their extraction algorithms. In this paper, it is shown that the improved iterative algorithm for watermark extraction from the encoded video can be successfully applied in the wireless environment. The efficiency of the improved algorithm is evaluated in the simulated wireless environment. In the wireless environment with 1% of dropped packets SSIM index was corrected by 24%, while in the environment with 2% of dropped packets SSIM index was corrected by 27.7%.
