Side information has a significant influence on the rate-distortion（RD） performance of distributed video coding（DVC）. In the conventional motion compensated frame interpolation scheme, all blocks adopt the same side-information generation method regardless of the motion intensity inequality at different regions. In this paper, an improved method is proposed. The image blocks are classified into two modes, fast motion and slow motion, by simply computing the discrete cosine transformation（DCT） coefficients at the encoder. On the decoder, it chooses the direct interpolation and refined motion compensated interpolation correspondingly to generate side information. Experimental results show that the proposed method, without increasing the encoder complexity, can increase the average peak signal-to-noise ratio（PSNR） by up to 1~ 2 dB compared with the existing algorithm. Meanwhile, the proposed algorithm significantly improves the subjective quality of the side information.

In order to overcome the security and integrity problems of the traditional university file information resource sharing model, the paper proposes a new cloud computing-based university file information resource sharing model. Supported by the cloud computing system architecture, the use of cloud computing search algorithms to fully excavate university archives information resources to realize the comprehensive sharing of university information archives, and calculate the utility parameters of university archives information resource sharing based on the mining results of cloud computing , and build a communication consumption matrix for the sharing of archives information resources in colleges and universities, and complete the construction of the sharing model of archives information resources in colleges. The comparative experiment results show that compared with the traditional sharing model, the intrusion rate and sharing transmission loss of the constructed sharing model are significantly reduced, indicating that the constructed model can effectively realize the sharing of archive information resources in universities and ensure the integrity and safety of archives.

A scheme of variable bit rate video coding for ATM networks is proposed in this paper. A two-layer coding method of image sequences using wavelet transform over a VBR network is given, and, the statistical multiplexing gain of the WT coding scheme over ATM-BISDN networks is also computed. The computing simulation results of the mean SNR and the mean data compression rate of reconstructed images with WT show that the subjective and the objective qualities of reconstructed images using proposal coding scheme are satisfied.

Trust is an important factor to consider when selecting a cloud computing provider. While some security models have failed to provide extended trustworthy in this space, this paper aims to propose a new approach to entering and trusting cloud computing. The proposed approach consists of developing a cloud computing trust model (CCTM) through a cloud computing security solution called H-AES. CCTM is designed with security features in mind and contains elements that are needed to build trust in a cloud computing environment. The CCMT model was derived heuristically based on literature review and surveying IT professionals. H-AES is a hardware implementation of the advanced encryption standard (AES) for data in transmission and is able to encrypt, decrypt and transmit information in a real time communication mode.
