Using high-level models for the creation of staged participatory multimedia events on TV

Abstract

Broadcasted television shows are becoming more interactive. Some broadcast TV shows allow even home viewers without professional equipment to be part of them. In this paper we present an approach that takes this concept even further. In the proposed kind of participation television viewers will not only participate in the show through interaction or video streams, but also be able to create and host their own show. The core of the presented approach consists of the use of high-level models to describe the different aspects of the television show, and a generic runtime environment. This paper discusses this type of participation television, Staged Participatory Multimedia Events, and the supporting runtime environment in more detail. It also introduces the tool and the models that are used to support graphical creation of the structure and appearance of Staged Participatory Multimedia Events. 1

Virtual World Television Products and Practices: Comparing Television Production in Second Life to Traditional Television Production

“…The audience was invited into the virtual environment to participate in the content production, which was recorded to be broadcast on traditional television. In their research, they built the digital environment in which production occurred and defined a framework within which the audience interacted and participated to generate content: the interaction between performers and the audience was recorded to broadcast (Van den Bergh et al, 2007). This production model replicates a similar procedure found across Web 2.0 technologies, which is understandable as virtual worlds are part of the Web 2.0 paradigm (Rak, 2009).…”

Cap3

“…Similarly additional symbols, such as the ParticipantElement and ActiveParticipantCollection as used in SPieLan [25] could be placed in a specific library complementing the interactors provided within CAP3 itself. Given appropriate tool support, this enables the creation of reusable modeling language extensions similar to the way reusable extensions are created for programming languages; through the creation of additional libraries.…”

“…Other interactors that are not part of CAP, can also belong to these groups of interactors. The Partici-pantElement and ActiveParticipantCollection as defined in SPieLan [25], for example, also belong to the interactors that show data; they are specialisations of respectively the Element and Collection interactors.…”

“…It shows that the user's current location is shown on the map and that the message in the user interface of the communication module of the application. It shows that a list of caregivers is shown using the ActiveParticipantCollection interactor, introduced in SpIeLan [25]. Figure 8 thus demonstrates how CAP3 supports context-sensitivity on two levels: it can be adapted to the modeling context by adding libraries that contain elements that specialize CAP3 elements, and through the explicit coupling with other models using "domain objects" one can model context-sensitive interactive applications.…”

“…interactive web applications), while another domain may prefer a small set of abstractions (e.g. participatory television [25]). Another reason may be that the focus of many research efforts was not the model itself, but the potential benefits for forward or backward engineering (in a specific domain), leading to incomplete descriptions of the modeling language itself in the publicly available literature.…”
