The article talks about Institute of Electrical & Electronics Engineers ComSoc Student Chapter in Brazil founded in 2015, Aldebaro Klautau as the adviser of the chapter, hosting the seminar on signal processing for MIMO systems and on hyper-spectral image analysis. It talks about the Forum for European ICT and Media Professionals exploring the e delivery and consumption of digital media and the International conference of Computer Network held in Poland.

The article focuses on the wireless communication services in Brazil. It was 1990 when the wireless experience in the country started. Cellular services were first deployed in Rio de Janeiro and Brasília. The national regulator of telecommunications services in the country is the agency, called the National Telecommunications Agency. Also noted is the official document of the Brazilian Ministry of Communications describing the Upgrading and Expansion Program for the Postal and Telecommunications System (PASTE), published in 1995.

The article profiles Nelson Fonseca, candidate for member-at-large of the Institute of Electrical & Electronics Engineers Inc. (IEEE) Communications Society. Fonseca received his doctorate degree in computer engineering from the University of Southern California in 1994. He is an associate professor at the State University of Campinas in Brazil and he has supervised almost 30 graduate students and has published almost 150 refereed papers. He used to be the director of the Online Services on the Board of Governors from 2002-2003 and is the chairman of the Multimedia Communications TC. Among his position statement notes that he will form channels to motivate members for the increase of their participation in the society.

Information about several papers discussed at the Institute of Electrical and Electronics Engineers/International Federation for Information Processing (IEEE/IFIP) Network Operations and Management Symposium held at Salvador da Bahia, Brazil from April 7-11, 2008 is presented. It focused on the management of information technology (IT) world. Several speakers discussed how to manage networks and services, spectrum management issues, and the terrestrial digital television system.

Large-scale testing and evaluation of network solutions are complex and typically involve multiple domains (e.g., optical, wireless, and cloud). The FUTEBOL project has deployed geographically distributed testbeds in Brazil and Europe that enable the experimentation and validation of new cross-domain network solutions. In this article, we introduce a control framework that allows experimenters to slice, reserve, and orchestrate optical, wireless, and cloud resources in a coordinated manner. We illustrate the features of our control framework and evaluate it through an experiment involving resource orchestration and automatic service scaling across multiple domains.

This article presents the innovative features of Ginga-NCL, an open middleware specification for multimedia IPTV services. Ginga-NCL relies on the Nested Context Language, a domain-specific declarative language targeting multimedia application authoring. As a glue language, NCL relates media objects in time and space without restricting or imposing any media content type, including media objects with imperative and declarative code written using other languages. Other NCL features include support for multidevice presentations, content adaptations, presentation adaptations, and advanced code reuse. Ginga-NCL allows NCL applications to be modified on the fly by means of live editing commands. Initially defined as the standard middleware for the Brazilian terrestrial DTV system, Ginga-NCL has recently become part of ISDB standards and an ITU-T Recommendation for IPTV services.

The upcoming terrestrial digital television technology brings a new class of services to traditional TV sets. A set-top box may, for example, access the Internet and send email. The interactive return channel makes these new services possible. This channel allows TV viewers to interact by sending data back to the TV broadcaster. In this article we analyze the viability of a wireless ad hoc network to implement the return channel. For this purpose, an ad hoc network is a low-cost and flexible solution. We evaluate the performance of an ad hoc return channel using the IEEE 802.11 wireless technology for different Brazilian geographical scenarios. The results show that ad hoc networking is a promising solution for the return channel of Brazilian interactive digital TV. [ABSTRACT FROM AUTHOR]
