Abstract

H.264/AVC is a novel video codec standard that provides a better coding efficiency than other previous video coding standard. In this paper, we provide a new error resilience using a reversible data embedding technique based on H.264/AVC. The algorithm is stretchy that user can make a trade-off between the quality of recovery image and DCT coefficients' variation. The advantage of reversible data embedding is that if the transmission is error-free, the image quality in the encoder can be exactly recovered by H.264 in the decoder. Simulation results demonstrate that the proposed method makes the video coding sequence more robust than the existing techniques.
