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...

We are currently developing the advanced broadcasting system for next generation of digital terrestrial television (DTTB). Its physical layer, Advanced Integrated Services Digital Broadcasting-Terrestrial (Advanced ISDB-T), is based on frequency division multiplexing, and large-scale field tests have been conducted at experimental transmitter stations. transport MPEG Media Transport (MMT), Inte...

We propose that enjoyment is an important factor in the adoption and long-term maintenance of exercise. Television (TV) viewing is believed to be a highly enjoyed leisure-time activity, combining it with exercise may make for a more enjoyable exercise experience. The objective of this study was to examine the effects of television (TV) viewing on psychological and physiological variables during...

In this paper, we describe a framework for the management of semantic metadata for audiovisual content description. The main objectives of this work are to provide a framework allowing enhanced retrieval performance, better support in the indexing phase and better user interfaces for audiovisual data, based on extensions of the well accepted international standards for the digital media, digita...

Through case analysis, questionnaire survey, data interpretation and other empirical research methods, this paper focuses on audiences’ reaction to current TV variety shows as a starting point, discusses the paradigm shift of uses gratifications approach possibility whether Chinese can satisfy demand under perspective media convergence in era new provides way for production broadcasting China.

IP-based networks such as the Internet have been the focal point for innovative technologies, services, and applications. These networks have enabled hugely successful services like the World Wide Web, and they are even attracting traditional services such as telephony. The service model for accessing Web content offers tremendous control and choice to users. In particular the on-demand nature ...

We consider a system with multiple interconnected video servers storing TV programs that are received through satellite antennas. Users, equipped with set-top boxes, submit requests for TV programs, to each of which they assign a utility value according to their preferences. We develop a distributed scheduling algorithm that selects the programs to be recorded and the servers to store them, so ...

As the capabilities of video standards and receiver hardware are increasing towards integrated 3d animations, generating realistic content is now becoming a limiting factor. In this paper we present a new technique of generating 3d content from reality, i.e. from video sequences acquired with normal TV cameras. The major aim is to provide the TV viewer with animated 3d reconstructions of athlet...
