TL;DR: Students in the e-learning environment that provided interactive video achieved significantly better learning performance and a higher level of learner satisfaction than those in other settings, and the findings suggest that it may be important to integrate interactive instructional video into e- learning systems.

TL;DR: An interactive video display system as mentioned in this paper is a system where a camera is used to detect an object in an interactive area located in front of the display screen, the camera operable to capture three-dimensional information about the object.
Abstract: An interactive video display system. A display screen is for displaying a visual image for presentation to a user. A camera is for detecting an object in an interactive area located in front of the display screen, the camera operable to capture three-dimensional information about the object. A computer system is for directing the display screen to change the visual image in response to the object.

TL;DR: In this paper, a method and apparatus for in-band, video broadcasting of commands to interactive devices is described, where control data are encoded by subliminally modulating, prior to the remote, composite video broadcast of video program material, a selected sequence of video image fields.
Abstract: Method and apparatus for in-band, video broadcasting of commands to interactive devices are described. Control data are encoded by subliminally modulating, prior to the remote, composite video broadcast of video program material, a selected sequence of video image fields. The resulting modulated video fields within the viewing area of a television, each having alternately, proportionately raised and lowered luminance horizontal scan lines, are monitored by a light sensitive device positioned adjacent the user's television screen. A semirigid, twisted pair cable connects the device to nearby receiver/transmitter electronics that discriminate the binary data from the program material and amplitude modulate a high frequency infrared (IR) carrier with the data. Interactive devices, e.g. educational aids or action toys, within range of the wireless IR transmission detect energy in this frequency range, decode the commands embedded in the control data, and selectively execute predetermined actions in response to the data-encoded broadcast. In a proposed modification, low radio frequency (RF) electromagnetic radiation emanating from the television's raster scan electronics is coupled by a conventional RF antenna to the receiver electronics, which identically discriminate the binary data, from the program material, for transmission to the interactive devices.

TL;DR: In this article, a system and method for providing interactive television services and for switching between television programs, such as to an interactive program session from another program, is described, where an interactive server, capable of providing requested interactive video services to a set of subscribers in a given geographic area, is coupled to a network to which subscriber set top boxes are also coupled.
Abstract: A system and method are described for providing interactive television services and for switching between television programs, such as to an interactive program session from another program. An interactive server, capable of providing requested interactive video services to a set of subscribers in a given geographic area, is coupled to a network to which subscriber set top boxes are also coupled. Television programming, which may be furnished by any number of sources, is accompanied by a signal that indicates the availability of other programming, such as interactive television service related to the program being viewed, as well as information to be used in requesting such service. The user, when notified by this signal, may input to the set top box a request for a second program, such as an interactive program or application. The identity of the original program channel is stored, and a session with the video service provider is established over the network. When the session is terminated, the set top box re-tunes the television signal to the original program channel.

TL;DR: This session discusses work in the forthcoming Polity title YouTube: Online Video and Participatory Culture by Joshua Green and Jean Burgess, which discusses the ways that it relates to wider transformations in culture, society and the economy.
Abstract: The three presentations in this session discuss work in the forthcoming Polity title YouTube: Online Video and Participatory Culture (2009) by Joshua Green and Jean Burgess. In this timely and comprehensive introduction to how YouTube is being used and why it matters, Burgess and Green discuss the ways that it relates to wider transformations in culture, society and the economy. The book critically examines the public debates surrounding the site, demonstrating how it is central to struggles for authority and control in the new media environment. Drawing on a range of theoretical sources and empirical research, the authors discuss how YouTube is being used by the media industries, by audiences and amateur producers, and by particular communities of interest, and the ways in which these uses challenge existing ideas about cultural 'production' and 'consumption'. Rich with concrete examples and featuring specially commissioned chapters by Henry Jenkins and John Hartley, the book is essential reading for anyone interested in the contemporary and future implications of online media. It will be particularly valuable for students and scholars in media, communication and cultural studies.
