The web-based technology allows anybody who has access to the Internet to get all kinds of information from the World Wide Web. It brings about issues regarding intellectual property and copyright threats. After content is downloaded, no further protection is provided on the content that has been accessed. DRM (Digital Right Management) technologies came out to ensure the protection of copyrighted content and information. In this paper, we propose architecture of license-based digital rights management system for protection of contents and principles' rights such as contents creators, providers, distributors, and uses in contents distribution value-chain over Internet. This system makes on-line processing of all value-chain from creator to purchaser possible, compared with existing DRM products only supporting only limited distribution between distributor and purchaser.

Video Content owners seek to squeeze the maximum amount of revenue from their assets via distribution into more territories. Digital Cinema Package(DCP), trusted solution to distribute protected content to theaters, caters to relatively small user base, which limits revenue. With the growth of the Internet & other digital media, the economics of media content has changed dramatically. Security remains main concern to deliver content to millions of consumers using intelligent digital display devices like Tablets, Smartphones, Smart TVs, Desktop & Laptop. By making the video content available to this segment securely, content owners will benefit from increased revenue. Through this paper we propose Open Source HomeDCP model to distribute the content to home users for offline viewing. We propose to include other open source CODEC than JPEG2000/MPEG2, which are specifically designed for theatrical performance. Final image size will be further reduced considering the display device resolution where video will be finally played. Key Delivery Message(KDM) system to be altered to suit new devices. This will be a big boost to Content Economy as content owners would be able to distribute the content securely to the wider audience & ensure more revenue.

Digital hybrid image expands the contradictory combination of physical reality and filmic fantasy. It is inevitable to recount Walter Benjamin' s concept of mechanical reproduction in the age of digital cinema. The modern condition of image arts changes the concept of mechanical reproduction to the logic of digital configuration. In addition, computer simulation innovates the film aesthetics of montage to the aesthetics of digital collage. The technological and aesthetical development of computer simulation and internet network leads to the new ontology of digital hybrid images. This study suggests a new theoretic point that the aesthetic ontology of digital hybrid images leads to the expansion of filmic fantasy and expression.

There is growing recognition that individuals with mental retardation are particularly vulnerable to sexual abuse due to multiple factors including life-long dependence on adults for care, trained compliance, social isolation, lack of education about sexuality and sexual abuse, and a societal view that devalues people with disabilities. Teaching about sexual abuse only may raise an individual's anxiety without promoting a healthy sexual identity. For many individuals with mental retardation, the provision of formal sexual health education and sexual abuse prevention training has been shown to be protective against exploitation as well as increase appropriate sexual behavior. To maximize the reach of formal sexual health education and abuse prevention promotion effort, this article suggest exploiting the internet and digital contents as delivery vehicles that have uniquely suitable communication characteristics and outstanding ability to reach large numbers of persons with mental retardation. We review the sexual health education programs, utilizing the internet and digital contents, for individuals with mental retardation. We also suggest the revised version of the Information-Motivation-Behavioral Skills (IMB) model of health behaviour change (Fisher & Fisher, 1992), and give a brief discussion of how useful this model is for constructing a life-long sex education program for persons with mental retardation.
