	abstract = {<p>Video compression has become very important as demand has increased for the storage and transmission of digital video content. Popular video compression schemes like MPEG encoding make use of block-transform coding techniques which are susceptible to blocking artifacts. Recently, an efficient deblocking algorithm based on the concept of shifted thresholding has been proposed. This algorithm uses only integer arithmetic and replaces division operations with bit shifting. This paper proposes a new hardware architecture for the implementation of video deblocking using shifted thresholding. A prototype system for high performance video deblocking using a FPGA (field programmable gate array) board is described. The prototype system leverages the reduced hardware complexity of the shifted thresholding algorithm to cost-effectively implement video deblocking on a FPGA board.</p>

	abstract = {<p>The emergence of online digital media sales services has given rise to the issue of online digital rights management (DRM). This paper presents a novel approach to online digital rights management and video content protection through the use of adaptive perceptual degradation based on usage. The proposed system facilitates the sharing of purchased digital videos between users while offering an incentive for users to acquire original video content through legal means. This is accomplished by adaptively degrading the quality of the digital video content based on a number of usage factors such as the number of times viewed and the number of copies made. Experimental results demonstrate the effectiveness of this system in striking a balance between the freedom of file sharing and content protection</p>
