Implementation of CAVLD Architecture Using Binary Tree Structures and Data Hiding for H.264/AVC Using CAVLC Exp Golomb Codeword Substitution
Abstract Data hiding is necessary in the encrypted video to maintain security and privacy. This paper presents, a novel scheme of data hiding in the encrypted version using CAVLC Exp Golomb codeword substitution and architecture to minimize memory space in CAVLD of H.264/AVC using Binary tree Structures. To solve the problem of decoding a great number of syntax elements based on look up tables, an efficient decoding has been designed using binary tree structures. Experimental results have demonstrated the feasibility and efficiency of proposed scheme.
