Semi-automated creation of converged iTV services: From macromedia director simulations to services ready for broadcast

While sound and video may capture viewers’ attention, interaction can captivate them. This has not been available prior to the advent of Digital Television. In fact, what lies at the heart of the Digital Television revolution is this new type of interactive content, offered in the form of interactive Television (iTV) services. On top of that, the new world of converged networks has created a demand for a new type of converged services on a range of mobile terminals (Tablet PCs, PDAs and mobile phones). This paper aims at presenting a new approach to service creation that allows for the semi-automatic translation of simulations and rapid prototypes created in the accessible desktop multimedia authoring package Macromedia Director into services ready for broadcast. This is achieved by a series of tools that de-skill and speed-up the process of creating digital TV user interfaces (UI) and applications for mobile terminals. The benefits of rapid prototyping are essential for the production of these new types of services, and are therefore discussed in the first section of this paper. In the following sections, an overview of the operation of content, service, creation and management sub-systems is presented, which illustrates why these tools compose an important and integral part of a system responsible of creating, delivering and managing converged broadcast and telecommunications services. The next section examines a number of metadata languages candidates for describing the iTV services user interface and the schema language adopted in this project. A detailed description of the operation of the two tools is provided to offer an insight of how they can be used to de-skill and speed-up the process of creating digital TV user interfaces and applications for mobile terminals. Finally, representative broadcast oriented and telecommunication oriented converged service components are also introduced, demonstrating how these tools have been used to generate different types of services

Open-standards rich media mobile platform & rapid deployment service creation tool

This paper builds upon the work carried out by Brunel University in the field of "Fast Prototyping And Semi-automated User Interface And Application Generation for Converged Broadcast and Cellular Terminals" [1]. This work involved the development of a service creation application for interactive services on mobile devices and methodologies and tools to speed up and deskill the deployment process. This paper aims at further enhancing these tools and presents an enhanced open standards reference platform for mobile digital TV and rich media services. By using a Scalar Vector Graphics (SVG)-driven Java MIDP application (as opposed to bitmapped raster graphics-driven MHP), rich media services can be broadcast to mobile devices running various Java-supported platforms with a user interface scalable to any screen size. Moreover, the Rich Media Mobile Browser is integrated into a service creation tool, therefore enabling rapid testing and deployment of rich mobile media services. The following sections detail the motivation behind the need for a platform which allows for rich media play-out on mobile devices, along with the rich media mobile viewing application and the tools used to create and test rich media with speed and ease

Using multimedia to enhance the accessibility of the learning environment for disabled students: reflections from the Skills for Access project

As educators' awareness of their responsibilities towards ensuring the accessibility of the learning environment to disabled students increases, significant debate surrounds the implications of accessibility requirements on educational multimedia. There would appear to be widespread concern that the fundamental principles of creating accessible web‐based materials seem at odds with the creative and innovative use of multimedia to support learning and teaching, as well as concerns over the time and cost of providing accessibility features that can hold back resource development and application. Yet, effective use of multimedia offers a way of enhancing the accessibility of the learning environment for many groups of disabled students. Using the development of ‘Skills for Access’, a web resource supporting the dual aims of creating optimally accessible multimedia for learning, as an example, the attitudinal, practical and technical challenges facing the effective use of multimedia as an accessibility aid in a learning environment will be explored. Reasons why a holistic approach to accessibility may be the most effective in ensuring that multimedia reaches its full potential in enabling and supporting students in learning, regardless of any disability they may have, will be outlined and discussed

Customized television: Standards compliant advanced digital television

This correspondence describes a European Union supported collaborative project called CustomTV based on the premise that future TV sets will provide all sorts of multimedia information and interactivity, as well as manage all such services according to each user’s or group of user’s preferences/profiles. We have demonstrated the potential of recent standards (MPEG-4 and MPEG-7) to implement such a scenario by building the following services: an advanced EPG, Weather Forecasting, and Stock Exchange/Flight Information

1001stories+: An effective and affordable multi-media, multi-format communication framework for cultural heritage institutions

Over the last decade, there has been an increasing number of technologies and devices (including smartphones, tablets and alike) able to provide new perspectives for the use of multimedia applications in the field of Cultural Heritage. This work arises from the interest in providing better authoring/delivery possibilities to cultural heritage institutions (small and medium sized in particular). Indeed, often medium and small sized museums do not have the necessary resources to create high quality multimedia productions. Not only have they faced short time and low budget, but a shortage of dedicated staff. Based on an interdisciplinary approach, this thesis focuses on the development of an effective and affordable multi-media, multi-format communication framework. The framework provides institutions with guidelines and methodologies and it is based on an innovative authoring tools (not developed in this thesis, but available). Specific concerns of the framework are: developing multimedia content within a short time span, developing multimedia content with a limited, low-budget, adapting multimedia content to different technologies and to different user experiences, making possible to “reuse multimedia content” (e.g. from websites, to audio guides, to multimedia guides, to YouTube or to paper brochures) This research has been conducted throughout parallel and intertwined processes, requiring a take of perspective. One the one hand, a general investigation (about multimedia formats, technologies and methodologies for production) has been conducted. On the other hand, an empirical work on real-life multimedia productions has been undergone. Indeed, the merging of theoretical knowledge and real fieldwork remains the main characteristic of this study’s methodological approach and of its strength. Its overall result is a fully developed framework (named 1001stories +), providing: multi-media, content information is presented throughout different media, including images, text, audio, and video; effective, the content can have the desired impact on the audience; affordable, content can be created in a short time, within low budget, and can be reused; multi-technology, content is available on different channels (web, smart phones, tablets, You tube, etc…); multi-format, content can be reorganized into various solutions, generating different formats for different user experiences. A more conceptual contribution of this thesis is about consideration of what communication in the Cultural Heritage domain is about, what its purposes are, and what the most appropriate means to reach the potential audience may be

Multimedia authoring, development environments, and digital video editing

Multimedia systems integrate text, audio, video, graphics, and other media and allow them to be utilized in a combined and interactive manner. Using this exciting and rapidly developing technology, multimedia applications can provide extensive benefits in a variety of arenas, including research, education, medicine, and commerce. While there are many commercial multimedia development packages, the easy and fast creation of a useful, full-featured multimedia document is not yet a straightforward task. This paper addresses issues in the development of multimedia documents, ranging from user-interface tools that manipulate multimedia documents to multimedia communication technologies such as compression, digital video editing and information retrieval. It outlines the basic steps in the multimedia authoring process and some of the requirements that need to be met by multimedia development environments. It also presents the role of video, an essential component of multimedia systems and the role of programming in digital video editing. A model is described for remote access of distributed video. The paper concludes with a discussion of future research directions and new uses of multimedia documents
