This paper introduces a platform to support the provision of pedagogical units especially designed to Interactive Digital TV. We have developed an authoring tool to create the educative content according to both the technical and social peculiarities of this new media. Besides, a set of software modules were also set up to support the suitable broadcasting and visualization in the receiver devi...

In this paper we describe the potential of multi-antenna techniques (MIMO) in the context of digital video broadcasting (DVB) systems. DVB standards have been challenged by the increasing demand of high data rate applications and larger indoor coverage area. MIMO is a key technology to increase the system capacity and link reliability without any additional bandwidth or transmit signal power. T...

The migration from analog to digital of the broadcasting technologies, already well consolidated for satellite systems, is becoming a reality also for terrestrial transmission. Digital Terrestrial Television (DTT) is also evolving to offer interactive services and a degree of flexibility which can be exploited to offer tailored applications to users which include, for instance interactivity, di...

This paper explores and presents scenarios and business models for mobile network operators (MNOs) in the novel hybrid use spectrum sharing concept of the Ultra High Frequency broadcasting spectrum (470-790 MHz) used for Digital Terrestrial TV (DTT) and Mobile Broadband (MBB). More flexible use of the band could lead to higher efficiency in delivering fast growing and converging MBB, media and ...

The purpose of this study is to examine how brand recall and recognition are affected by non-editorial clutter in mega-event broadcasting. Using longitudinal data collected during four years of Super Bowl broadcasts, this study investigates the effects of three different types of television clutter (other ads, on-air promos and TV billboards) and their composite effects on brand memory. The res...

T-learning courses are an effective way of education, but their creation is a time-consuming and expensive activity. We explain the process of t-learning courses development as it was proposed in the scope of the ELU Project. We suggest applying the combination of hyper-text on the basis of an electronic programme guide for navigation in the t-course structure and a video with active elements i...

The Brazilian soccer tournament is organized every year by the Brazilian Soccer Confederation. Its major sponsor is TV Globo, the largest media group and television network in Brazil, who imposes constraints on the games to be broadcast. Scheduling the games of this tournament is a very constrained problem, with two objectives: breaks minimization (fairness) and the maximization of the revenues...
