- Abstract
- This paper proposes a new error resilient MPEG-2 video coding scheme based on the TLECC (Three Layer Error Control Coding) techniques using information hiding. We embed the watermark signal into intra frames using a DCT-based algorithm, which shows very reliable outcome under noises and attacks. Meanwhile, we have implemented the DEMV (Data Embedding in Motion Vector) algorithm for inter frames. In the decoder, we apply TLECC scheme to find embedded signal and corrupted position. Experimental results demonstrate that DCT-based algorithm and DEMV algorithm for normal video like "Foreman" are strong and reliable. ECC (Error Control Coding) is further incorporated into the watermarking scheme. Two different ECC methods such as BCH and RS codes have been implemented and experimented. All these codes have the error correction capability up to 10% or 25%. We have done various noise recovery experiments, which show good recovery results under distributed noises.
