Methods and Applications in Interactive Broadcasting
Abstract
Interactive TV technology has been addressed in many previous works, but there is sparse research on the topic of interactive content broadcasting and how to support the production process. In this article, the interactive broadcasting process is broadly defined to include studio technology and digital TV applications at consumer set-top boxes. In particular, augmented reality studio technology employs smart-projectors as light sources and blends real scenes with interactive computer graphics that are controlled at end-user terminals. Moreover, TV producer-friendly multimedia authoring tools empower the development of novel TV formats. Finally, the support for user-contributed content raises the potential to revolutionize the hierarchical TV production process, by introducing the viewer as part of content delivery chain.
... • "Create once, publish everywhere" approaches that are proposed by the media industry (Chorianopoulos & Lekakos, 2007). Similar to responsive design, it would be interesting to explore ways where content is seamlessly distributed across all available touchpoints, maintaining its usability while enhancing the shopping experience. ...
The increasing availability of electronic applications in physical retail stores has created a series of interesting research opportunities with challenging managerial implications for practitioners. Since the graphical user interface design constitutes a critical user-consumer influencing factor in the context of a multichannel retailing environment, there are several multidisciplinary research initiatives that could add value towards an integrated investigation of this topic. To this end, the paper discusses the promising role of combining Information Systems and Marketing disciplines for conducting behavioural studies in the context of multichannel/omnichannel retailing, approaching humans both as users of information systems and consumers of retail stores. Similarly, the paper treats the screen of the electronic applications available in online and offline retail stores both as a graphical user interface of an information system and as the atmosphere/servicescape of a retail store. The paper provides several future research directions and practical implications for this fast evolving topic.
This paper investigates the use of streaming multimedia narratives in web entertainment. Based on experience gained during the user centered design of a website for art and culture, we provide evidence that users want and like "less clicking, more watching" web experiences where the point of view of experts, artists, or celebrities is presented in a narrative form. We conducted a study where users evaluated two prototypes of cultural tours which stream continuously for several minutes unless the user chooses to exercise control over the flow or to explore hot links that lead to extra information. Those tours were positively evaluated as both entertaining and engaging. By analyzing mouse activity, we determined that users who interacted more tended to report less entertainment and engagement. We also found that such "watchable" experiences are not necessarily a solitary experience and can be enjoyed by groups of people. Finally, users see the web experiences as a highly enriching and accessible way to augment the cultural experiences and performances they enjoy in brick and mortar cultural institutions around the world, rather than as a substitute for them.
For pt.I see ibid., (Oct-Dec. 1998). In the first part of our
project report, we described a new technique for multimedia broadcasting
over the Internet, called IP Simulcast. In this article we introduce a
new video compression technique, called XYZ compression, which suits
ultra-low bandwidth applications very well
Although the industry is still in the early stages of webcasting,
we can already foresee what the Internet will offer a few years down the
line: clear, crisp audio and full-screen, high-quality, on-demand video.
We have developed a technology that provides all these required features
for Internet webcasting. This technology consists of: IP Simulcast, a
new Internet broadcast protocol, which provides inexpensive, efficient,
and reliable audio and video broadcasting; and new audio and video
compression algorithms, which allow real-time audio and video
transmission of data at low bit rates and with high quality. In this
article, we describe a new Internet broadcast technology
In this paper we describe and analyse the community building process for Ages of Avatar, a set of on-line Collaborative Virtual Environments created in Microsoft Virtual Worlds, which form part of an ongoing experiment in Inhabited Television, aiming to merge CVEs and broadcast media. We describe the means by which the CVEs were launched, promoted and supported alongside a television broadcast channel, and how actions of viewers acting as inhabitants in the CVE can be used to provide broadcast material. We explain how the world content and their super-structure were managed to encourage the growth of a community over a short period of time. Using logs of activities in the worlds we deduce some of the characteristics of the community which was formed. Keywords Collaborative Virtual Environments, Virtual Communities, Inhabited Television.
Abstract An examination of television as a center of meaning and as a social context supports the concept of a place without a location. Similar ideas have appeared in media theory since the 1960s, but have not been the subject of geographic research. Comparison of television with other media, including books, radio, and film, reveals that it is uniquely place-like. Television functions as a social context, providing sensory communion and social congregation; it also functions as a center of meaning, helping a society define “us” and “them,” conferring value on persons and objects, and, possibly, supporting hegemonic social control. A comparison of television and certain architectural structures identifies similarities and differences that may be related to long-term historical changes in society.
We explore the generation of interactive computer graphics at digital set-top boxes in place of the fixed graphics that were embedded to the television video before the broadcast. This direction raises new requirements for user interface development, since the graphics are merged with video at each set-top box dynamically, without the traditional quality control from the television producers. Besides the technical issues, interactive computer graphics for television should be evaluated by television viewers. We employ an animated character in an interactive music television application that was evaluated by consumers, and was developed using the Virtual Channel Control Library, a custom high-level API, that was built using Microsoft Windows and TV technologies.
