Study of CABAC-based digital video encryption in the H.264/AVC standard
Published 2007-01-01“…Several candidate domains were analyzed and summarized to apply encryption to the latest video coding standard H.264/AVC,and a novel digital video encryption scheme based on CABAC(context-based adaptive binary arithmetic coding) was proposed.During the CABAC encoding,two kinds of secure encryption operations including RCME(regular coding mode encryption) and BCME(bypass coding mode encryption) were utilized,in order to encrypt residual coefficient codeword,motion vector difference codeword and intra-prediction mode,respectively.The experimental results show that the scheme has significant advantages on security,coding efficiency,and errors robustness.…”

Research on side information generation algorithm for Wyner-Ziv video coding
Published 2010-01-01“…To reduce the block artifacts and ghosting artifacts of side-information frame in Wyner-Ziv video coding,an overlapped block bi-directional motion compensation algorithm based on the original-image correlation was proposed.Firstly,the correlation of the original image in the encoder is calculated and sent to the decoder.Secondly,the correlation data is used to motion estimation in the decoder to get more accurate motion vector.Then the side information is gener-ated by bi-directional motion compensation.Compared with the existing algorithm,the proposed method can increase the average PSNR(peak signal-to-noise ratio) by 1.5~3dB,and also significantly improve the subjective quality of the side information.…”
