WANG Yin-miao, BAO Xian-yu. Study of CAC-based Secure Coding of Digital Video[J]. Journal of Image and Graphics, 2010, 15(1): 1. DOI: 10.11834/jig.20100101.
based adaptive coding (CAC) is a class of new high-efficient entropy coding techniques for video compression. In this paper
a CAC-based scheme is presented to achieve realtime secure coding for digital video
and a secure coding chain is built based on CAC secure coder. Two kinds of secure coding operations
including context-based adaptive binary arithmetic secure coding (CABASC) and context-based adaptive variable length secure coding (CAVLSC)
are given. The experimental results show that this scheme has significant improvement on security
real-time performance and flexibility of software implementation. These properties make it a sound foundation for further research on CAC secure coding.
