Abstract

With increasing the volume of digital multimedia market, the security and multimedia content protection issues are arising. Interest in H.264/AVC is emerging and special features in H.264/AVC element stream must be considered. We developed a new algorithm which scrambles and descrambles H.264/AVC element stream in compressed domain using manipulating CABAC initialization table and DCT coefficients. Extensive experimental results indicate that the proposed algorithm is effective and promising.
