The potential of digital interactive television for the provision of healthcare and wellness services

The potential of digital interactive television (iDTV) to promote original services, formats and contents that can be relevant to support personal health care and wellness of individuals, namely elderly people, has not been yet fully explored in the past. Therefore, in a context of rapid change of the technological resources, in which the distribution and presentation of content comes associated with new platforms (such as digital terrestrial TV and IPTV), it is important to perceive the configurations that are being developed for interactive digital TV (iDTV) that may result in relevant outcomes within the field of healthcare and wellness, with the aim of offering complementarity to the existing services and contents made available today via the traditional means and media. This article describes and discusses the preliminary results of the first part of the research project iDTV-HEALTH: Inclusive services to promote health and wellness via digital interactive television. These first results suggest that iDTV solutions may represent a real contribution to delivery healthcare and wellness to the target population, namely as a supplement to health services provision.

Inviting the Audience – Interactive, Participatory, and Social Television in Finland

The television and the ways it has invited the audience to take part have been changing during the last decade. Today’s interaction, or rather participation, comes from multiplatform formats, such as TV spectacles that combine TV and web platforms in order to create a wider TV experience. Multiplatform phenomena have spread television consumption and traditional coffee table discussions to several different devices and environments. Television has become a part of the bigger puzzle of interconnected devices that operates on several platforms instead of just one. This thesis examines the Finnish television (2004–2014) through the notion of audience participation and introduces the technical, thematic, and social linkages as three different phases, interactive, participatory, social, and their most characteristic features in terms of audience participation. The aim of the study is also to focus on the idea of a possible change by addressing the possible and subtler variations that have taken place through the concept of digital television. Firstly, Finnish television history has gone through numerous trials, exploring the interactive potential of television formats. Finnish SMS-based iTV had its golden era around 2005, when nearly 50% of the television formats were to some extent interactive. Nowadays, interactive television formats have vanished due to their negative reputation and this important part of recent history is mainly been neglected in the academic scope. The dissertation focuses also on the present situation and the ways television content invites the audience to take part. “TV meets the Internet” is a global expression that characterises digital TV, and the use of the Web combined with television content is also examined. Also the linkages between television and social media are identified. Since television can nowadays be described multifaceted, the research approaches are also versatile. The research is based on qualitative content analysis, media observation, and Internet inquiry. The research material also varies. It consists of primary data: taped iTV formats, website material, and social media traces both from Twitter and Facebook and secondary data: discussion forums, observations from the media and Internet inquiry data. To sum up the results, the iTV phase represented, through its content, a new possibility for audiences to take part in a TV show (through gameful and textual features) in real-time. In participatory phase, the most characteristic features from TV-related content view, is the fact that online platform(s) were used to immerse the audience with additional material and, due to this, to extend the TV watching enjoyment beyond the actual broadcast. During the Social (media) phase, both of these features, real-timeness, and extended enjoyment through additional material, are combined and Facebook & Twitter, for example, are used to immerse people in live events (in real-time) via broadcast-related tweets and extra-material offered on a Facebook page. This thesis fills in the gap in Finnish television research by examining the rapid changes taken place on the field within the last ten years. The main results is that the development of Finnish digital television has been much more diverse and subtle than has been anticipated by following only the news, media, and contemporary discourses on the subject of television. The results will benefit both practitioners and academics by identifying the recent history of Finnish television.

Video Composer and Live Video Conductor: Future Professions for the Interactive Digital Broadcasting Industry

Innovations in hardware and network technologies lead to an exploding number of non-interrelated parallel media streams. Per se this does not mean any additional value for consumers. Broadcasting and advertisement industries have not yet found new formats to reach the individual user with their content. In this work we propose and describe a novel digital broadcasting framework, which allows for the live staging of (mass) media events and improved consumer personalisation. In addition new professions for future TV production workflows which will emerge are described, namely the 'video composer' and the 'live video conductor'.

Methods and Applications in Interactive Broadcasting

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.

MHP Oriented Interactive Augmented Reality System for Sports Broadcasting Environments

Television and movie images have been altered ever since it was technically possible. Nowadays embedding advertisements, or incorporating text and graphics in TV scenes, are common practice, but they can not be considered as integrated part of the scene. The introduction of new services for interactive augmented television is discussed in this paper. We analyse the main aspects related with the whole chain of augmented reality production. Interactivity is one of the most important added values of the digital television: This paper aims to break the model where all TV viewers receive the same final image. Thus, we introduce and discuss the new concept of interactive augmented television, i. e. real time composition of video and computer graphics - e.g. a real scene and freely selectable images or spatial rendered objects - edited and customized by the end user within the context of the user's set top box and TV receiver.

Protection of publicly distributed software components

The nature of client-server architecture implies that some modules are delivered to customers. These publicly distributed commercial software components are under risk, because users (and simultaneously potential malefactors) have physical access to some components of the distributed system. The problem becomes even worse if interpreted programming languages are used for creation of client side modules. The language Java, which was designed to be compiled into platform independent byte-code is not an exception and runs the additional risk. Along with advantages like verifying the code before execution (to ensure that program does not produce some illegal operations)Java has some disadvantages. On a stage of byte-code a java program still contains comments, line numbers and some other instructions, which can be used for reverse-engineering. This Master's thesis focuses on protection of Java code based client-server applications. I present a mixture of methods to protect software from tortious acts. Then I shall realize all the theoretical assumptions in a practice and examine their efficiency in examples of Java code. One of the criteria's to evaluate the system is that my product is used for specialized area of interactive television.

Discrimination of media moments and media intervals: sticker-based watch-and-comment annotation

In this paper we discuss the problem of how to discriminate moments of interest on videos or live broadcast shows. The primary contribution is a system which allows users to personalize their programs with previously created media stickers-pieces of content that may be temporarily attached to the original video. We present the system's architecture and implementation, which offer users operators to transparently annotate videos while watching them. We offered a soccer fan the opportunity to add stickers to the video while watching a live match: the user reported both enjoying and being comfortable using the stickers during the match-relevant results even though the experience was not fully representative.

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.

Exploiting OSGi capabilities from MHP applications

In this paper we introduce a cooperative environment between the Interactive Digital TV (IDTV) and home networking with the aim of allowing the interaction between interactive TV applications and the controllers of the in-home appliances in a natural way. More specifically, our proposal consists of merging MHP (Multimedia Home Platform), one of the main standard frameworks for IDTV, with OSGi (Open Service Gateway Initiative), the most widely used open platform to set up Residential Gateways. To overcome the radically different nature of these specifications the function-oriented MHP middleware and the service-oriented OSGi framework , we define a new kind of application, coined as XbundLET. Although this software bridge is suitable to enable the interaction between MHP and OSGi applications in both directions, we concretely focus on exposing our implementation experience in only one direction: from MHP to the OSGi world.
