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 ...

We present a novel algorithm, architecture, and high-level Simulink prototyping for visible watermarking of MPEG-4 video streams. The watermark is inserted in the video stream during compression, resulting in an optimized compression/watermarking algorithm and system. Discrete Cosine Transform (DCT) watermarking, due to its robust nature, was chosen in this work to accomplish MPEG-4 video copyr...

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...

INTRODUCTION We aimed to assess longitudinal changes in television (TV) food advertising during 2013 compared to 2007, measuring children's exposure to healthy and unhealthy advertisements, after the new European and Spanish Public Health laws published in 2011. MATERIAL AND METHODS Two thematic channels for children (TC), and 2 generalist channels (GC) for all ages were recorded, between Apr...

Internet-based interactive TV is an emerging field that is affected by advances in various research areas including communication, interactivity, network efficiency, content management and aesthetics. Despite constantly reducing costs in the area of broadcast infrastructure development, this new medium has yet to claim its market position and recognition. Various reasons may be identified for t...

In this paper we study the availability of TV white spaces in Europe. We focus specifically on the 470–790 MHz UHF band that is still predominantly used for TV broadcasting also after the digital dividend (frequency reallocation as part of transition to digital TV), which has taken place or is ongoing in several European countries. We find that in the countries used in our studies, approximatel...

Smart TV, which enables viewers to conveniently access different multimedia contents and interactive services in a single platform, is currently becoming popular. The work presented here develops three new ways to enhance the performance of a smart TV. The first is to design a body control system that recognizes and interprets human gestures as machine commands to control the TV. The second is ...
