Error Concealment Techniques In H.264/AVC For Video Transmission Over Wireless Networks

Several error concealment methods are applied to H.264/AVC (Advanced Video Coding) baseline profile such that the decoded video is error free. The error concealment techniques are implemented both in the spatial and temporal domains. The original and error concealment video sequences are compared in terms of MSE (Mean Square Error), PSNR (Peak-to-peak Signal to Noise Ratio) and SSIM (Structural Similarity Index Metric). This comparision has demonstrated that the error concealment methods are very effective in improving the visual quality. Implementation complexity also has been considered as the video transmission in baseline profile is meant for wireless networks.
