Secure streaming container

Abstract: A system and method for securely streaming encrypted digital media content out of a digital container to a user's media player. This streaming occurs after the digital container has been delivered to the user's machine and after the user has been authorized to access the encrypted content. The user's operating system and media player treat the data stream as if it were a being delivered over the Internet (or other network) from a streaming web server. However, no Internet connection is required after the container has been delivered to the user and the data stream suffers no quality loss due to network traffic or web server access problems. In this process of the invention, the encrypted content files are decrypted and fed to the user's media player in real time and are never written to the user's hard drive or storage device. This process makes unauthorized copying of the digital content contained in the digital container virtually impossible.

Protocol: How Control Exists after Decentralization

Abstract: Is the Internet a vast arena of unrestricted communication and freely exchanged information or a regulated, highly structured virtual bureaucracy? In Protocol, Alexander Galloway argues that the founding principle of the Net is control, not freedom, and that the controlling power lies in the technical protocols that make network connections (and disconnections) possible. He does this by treating the computer as a textual medium that is based on a technological language, code. Code, he argues, can be subject to the same kind of cultural and literary analysis as any natural language; computer languages have their own syntax, grammar, communities, and cultures. Instead of relying on established theoretical approaches, Galloway finds a new way to write about digital media, drawing on his backgrounds in computer programming and critical theory. "Discipline-hopping is a necessity when it comes to complicated socio-technical topics like protocol," he writes in the preface. Galloway begins by examining the types of protocols that exist, including TCP/IP, DNS, and HTML. He then looks at examples of resistance and subversion -- hackers, viruses, cyberfeminism, Internet art -- which he views as emblematic of the larger transformations now taking place within digital culture. Written for a nontechnical audience, Protocol serves as a necessary counterpoint to the wildly utopian visions of the Net that were so widespread in earlier days.

Wag the Blog: How Reliance on Traditional Media and the Internet Influence Credibility Perceptions of Weblogs Among Blog Users

Abstract: This study surveyed Weblog users online to investigate how credible they view blogs as compared to traditional media as well as other online sources. This study also explores the degree to which reliance on Weblogs as well as traditional and online media sources predicts credibility of Weblogs after controlling for demographic and political factors. Weblog users judged blogs as highly credible—more credible than traditional sources. They did, however, rate traditional sources as moderately credible. Weblog users rated blogs higher on depth of information than they did on fairness.

The Next Generation of Educational Engagement

Abstract: Games are no longer just for fun; they offer potentially powerful learning environments. Today's students have grown up with computer games. In addition, their constant exposure to the Internet and other digital media has shaped how they receive information and how they learn. There are many attributes of games that make them pedagogically sound learning environments. An increasing number of faculty are using games as enhancements to the traditional learning environment with encouraging results. While the interactivity and engagement of games are highly positive a number of questions remain about how games will be developed, deployed and accepted in higher education.

An Investigation of the Status of Outdoor Play

Abstract: This study discusses the extent to which children in the USA today participate in active, outdoor play, compared with the previous generation. Eight hundred and thirty mothers nationwide were surveyed regarding their active, outdoor play experiences as children, as well as their children's play experiences today. The mother's play experiences, compared with the child's, clearly indicate that children today spend considerably less time playing outdoors than their mothers did as children. The study reveals several fundamental reasons for this decline, including dependence on television and digital media, and concerns about crime and safety. The study also conveys findings related to the frequent use of electronic diversions and discusses several suggestions for early childhood professionals, classroom teachers, and parents for fostering the child's enjoyment for outdoor play.

Digital Culture

Abstract: From our bank accounts to supermarket checkouts to the movies we watch, strings of ones and zeroes suffuse our world. Digital technology has defined modern society in numerous ways, and the vibrant digital culture that has now resulted is the subject of Charlie Geres engaging volume. In this revised and expanded second edition, taking account of new developments such as Facebook and the iPhone, Charlie Gere charts in detail the history of digital culture, as marked by responses to digital technology in art, music, design, film, literature and other areas. After tracing the historical development of digital culture, Gere argues that it is actually neither radically new nor technologically driven: digital culture has its roots in the eighteenth century and the digital mediascape we swim in today was originally inspired by informational needs arising from industrial capitalism, contemporary warfare and counter-cultural experimentation, among other social changes. A timely and cutting-edge investigation of our contemporary social infrastructures, Digital Culture is essential reading for all those concerned about the ever-changing future of our Digital Age. This is an excellent book. It gives an almost complete overview of the main trends and view of what is generally called digital culture through the whole post-war period, as well as a thorough exposition of the history of the computer and its predecessors and the origins of the modern division of labor.Journal of Visual Culture

Electromagnetism supercharged!: learning physics with digital simulation games

Abstract: Learning scientists are increasingly turning to computer and video games as tools for learning. Simulation might not only motivate learners, but provide accessible ways for students to develop intuitive understandings of abstract physics phenomena. This study examines what learning occurs when an electromagnetism simulation game is used in a school for underserved students. Students in the experimental group performed better than students in the control group (guided discovery-based science) on measures for understanding. Game mechanics enabled students to confront weaknesses in understandings, and physics representations became tools for understanding problems. Implications for the design of educational digital media are discussed. Yet, it was also these very same game mechanics posed significant challenges in terms of student engagement, motivation, and learning of physics concepts.

Algorithms for audio watermarking and steganography

Abstract: Broadband communication networks and multimedia data available in a digital format opened many challenges and opportunities for innovation. Versatile and simple-to-use software and decreasing prices of digital devices have made it possible for consumers from all around the world to create and exchange multimedia data. Broadband Internet connections and near error-free transmission of data facilitate people to distribute large multimedia files and make identical digital copies of them. A perfect reproduction in digital domain have promoted the protection of intellectual ownership and the prevention of unauthorized tampering of multimedia data to become an important technological and research issue. Digital watermarking has been proposed as a new, alternative method to enforce intellectual property rights and protect digital media from tampering. Digital watermarking is defined as imperceptible, robust and secure communication of data related to the host signal, which includes embedding into and extraction from the host signal. The main challenge in digital audio watermarking and steganography is that if the perceptual transparency parameter is fixed, the design of a watermark system cannot obtain high robustness and a high watermark data rate at the same time. In this thesis, we address three research problems on audio watermarking: First, what is the highest watermark bit rate obtainable, under the perceptual transparency constraint, and how to approach the limit? Second, how can the detection performance of a watermarking system be improved using algorithms based on communications models for that system? Third, how can overall robustness to attacks to a watermark system be increased using attack characterization at the embedding side? An approach that combined theoretical consideration and experimental validation, including digital signal processing, psychoacoustic modeling and communications theory, is used in developing algorithms for audio watermarking and steganography. The main results of this study are the development of novel audio watermarking algorithms, with the state-of-the-art performance and an acceptable increase in computational complexity. The algorithms' performance is validated in the presence of the standard watermarking attacks. The main technical solutions include algorithms for embedding high data rate watermarks into the host audio signal, using channel models derived from communications theory for watermark transmission and the detection and modeling of attacks using attack characterization procedure. The thesis also includes a thorough review of the state-of-the-art literature in the digital audio watermarking.

Windows Media Video 9: overview and applications

Abstract: Microsoft ® Windows Media 9 Series is a set of technologies that enables rich digital media experiences across many types of networks and devices. These technologies are widely used in the industry for media delivery over the internet and other media, and are also applied to broadcast, high definition DVDs, and digital projection in theaters. At the core of these technologies is a state-of-the-art video codec called Windows Media Video 9 (WMV-9), which provides highly competitive video quality for reasonable computational complexity. WMV-9 is currently under standardization by the Society of Motion Picture and Television Engineers (SMPTE) and the spec is at the CD (Committee Draft) stage. This paper includes a brief introduction to Windows Media technologies and their applications, with a focus on the compression algorithms used in WMV-9. We present analysis, experimental results, and independent studies that demonstrate quality benefits of WMV-9 over a variety of codecs, including optimized implementations of MPEG-2, MPEG-4, and H.264/AVC. We also discuss the complexity advantages of WMV-9 over H.264/AVC.

Agents of change: how young consumers are changing the world of marketing

Abstract: This paper looks at young adults' relationship with digital media. From a commercial perspective the opportunity to deploy these channels to promote consumer recruitment and loyalty is very significant indeed. However, consumer marketing companies will have to learn to meet the needs of this very discerning and highly cynical audience by combining the best creative ideas and strategies with a transformed approach to marketing sales and service, embodying the best of information and communications technology, reliably and securely implemented. Communication networks underpin this report. While teens complain that they have less public space to hang out in, they are making the online world their milieu, their domain where they develop personal relationships and where they play and learn new things. The conclusions cover not only the effect of current market drivers, but also emerging trends that will allow brands to better understand the behaviour of young adults, so as to establish more truthful binds with them.

Mobile station and interface adapted for feature extraction from an input media sample

Abstract: A mobile station has a processor and a user input mechanism such as a button that is operable to cause the processor to extract at least one feature from a digital media sample. The feature, such as a spectral centroid, is descriptive of an identity of a content of the media sample. Preferably, the same user input that causes the feature extraction also causes a transmitter to establish a link and to send a message to a network address, the message having a plurality of extracted features from which the digital media sample may not be reconstructed. Where a reply message identifies a media file that matches the media sample, another user input at the same or a different button causes an authorization message to be sent so that a copy of the media file, identified in the reply message and having features that exactly match the plurality of extracted and transmitted features, is downloaded to the mobile station.

Media service delivery system providing conditional access to media content from various client devices

Abstract: A system for protecting the digital rights of content owners allows digital media to be delivered to only those media rendering client devices that have been approved for the media content. Before delivering requested media, the media service provider may determines whether the media rendering client device that requested the media is the type of device that is authorized to receive the request media. If it is, the media service provider may transmit the media to a middleman server over a network (such as the Internet). A middleman server may then serves the media to the client device over a local network. By allowing the media content to be distributed to approved devices only, the media service provider can prevent a user from using the media in a way that is not authorized by the content owner.

The introduction of a shared interactive surface into a communal space

Abstract: We describe a user study of a large multi-user interactive surface deployed for an initial period within a real world setting. The surface was designed to enable the sharing and exchange of a wide variety of digital media. The setting for the study was the common room of a high school where students come together to mix, socialize, and collaborate throughout the day. We report on how the students use the new technology within their own established communal space. Findings show that the system was used extensively by the students in a variety of ways, including sharing of photos, video clips, and websites, and for facilitating social interaction. We discuss how the interactive shared surface was appropriated by the students and introduced into their everyday lives in ways that both mirrored and extended their existing practices within the communal space.

Digital media distribution and trading system used via a computer network

Abstract: A digital media file sharing system includes a fair share server, a user computer, and a second user computer. The fair share server includes a user library information database and a media library, the media library storing digital media files. A user computer includes a user computer media library and the user computer media library stores user digital media files. A second user computer includes a second user computer media library and requests the downloading of a selected digital media file from the user library information database. The second user computer downloads the selected digital media file from the user computer media library. The user computer is allocated a credit in the payment database of the fair share server for providing the selected digital media file to the second user computer.

Computers for communication, not calculation: media as a motivation and context for learning

Abstract: As the skills that constitute literacy evolve to accommodate digital media, computer science education finds itself in a sorry state. While students are more in need of computational skills than ever, computer science suffers dramatically low retention rates and a declining percentage of women and minorities. Studies of the problem point to the overemphasis in computer science classes on abstraction over application, technical details instead of usability, and the stereotypical view of programmers as loners lacking creativity. In spring 2003, Georgia Institute of Technology trialed a new course, Introduction to Media Computation, which teaches programming and computation in the context of media creation and manipulation. Students implement PhotoShop-style filters and digital video special effects, splice sounds, and search Web pages. The course is open only to noncomputer science and nonengineering majors at Georgia Tech, such as liberal arts, management and architecture students. The course is supported through the use of a Web-based collaboration environment where students actively share and discuss their digital creations. The results have been dramatic. 120 students enrolled, 2/3 female, and only three students withdrew. By the end of the semester, the combined withdrawal, failure and D-grade rate had reached 11.5% - compared to 42.9% in the traditional introductory computer science course. 60% of the students who took media computation reported that they would be interested in taking an advanced version of the course; only 6% reported that they would otherwise be interested in taking more computer science. Results of the trial indicate that media computation motivates and engages an audience that is poorly served by traditional computer science courses.

Cultures of Music Piracy An Ethnographic Comparison of the US and Japan

Abstract: In 2003, the US recording industry, hoping to change what some view as a ‘culture of piracy’, initiated lawsuits against its own consumers. What is this culture of piracy and what is at stake in trying to change it? In this article, I take an ethnographic look at music file-sharing, and compare the situation in the US with Japan, the second largest music market in the world. My findings are based on fieldwork in Tokyo, and surveys and discussions with US college students. By considering the ways social dynamics and cultural orientations guide uses of digital media technology, I argue that a legal and political focus on ‘piracy’ ignores crucial aspects of file-sharing, and is misleading in the assumptions it makes for policy. A focus on fan participation in media success provides an alternative perspective on how to encourage flourishing music cultures.

Indexing media files in a distributed, multi-user system for managing and editing digital media

Abstract: A scalable infrastructure indexes and tracks media data and metadata in a distributed, multi-user system. An indexer is associated with particular storage locations, such as a disk, or a directory on a disk, to maintain an index of media files or metadata stored in those storage locations. The indexer monitors activity on any storage location with which it is associated. Any additions, deletions or modifications to files in that storage location cause the indexer to update its index. This index then can be accessed by any of a number of applications in the same manner as conventional indexes. There may be different indexers for different storage locations. Separate indexers may be provided for media files and compositions that use those media files.
