Global ITV: Interoperability of Interactive and Hybrid TV systems. A new advanced scheme for future services and applications in a global environment

The Global ITV project aimed at creating a structure for exchanging HbbTV applications between Europe and Brazil, including analysis of middleware legacies in use today, such as Ginga in Brazil. In addition, the solution's architecture allows it to expand to other interactive digital television scenarios: in Japan, China, etc., thus creating the basis for a truly global HbbTV market. The proposal takes into account new trends to the user, such as video on demand, the use of social networks and the use of "second screen" concomitant with TV programming. The project was contemplated by the call of MCTI / CNPq nº 13/2012 - Cooperation Program Brazil - European Union, directed to the area of ​​Information and Communication Technologies - ICT. The project is coordinated, on the Brazilian side, by the Interdisciplinary Center for Interactive Technologies of the University of São Paulo (CITI / USP) and, on the European side, by the Study Group on Broadcasting from Institut für Rundfunktechnik, GmbH (IRT), Germany. In total, this project consists of 17 partners, European and Brazilian.

Building Smart Cities: from Instrumentation of Environments to Application Development

Smart Cities is a concept related to the provision of information and communication services to solve the problems of citizens in their urban conglomerates, and to ensure better public management. A smart city needs solutions to various problems, such as: traffic, surveillance, emergency care, environmental monitoring, health, education and digital inclusion, as well as allowing greater efficiency and transparency in public management. To support these solutions, the various urban data need to be collected and disseminated through communication infrastructures, which in turn require integrated, heterogeneous, and intelligent forms of wireless communication. In addition, both communication and applications need to be energy efficient in an overload and emergency situation. In this context, the present project proposes to build an instrumentation, computing and communication infrastructure for the feasibility of Smart Cities, ranging from the acquisition of raw urban data through sensor network technologies and internet of things, communication, storage , and access to this data through different wireless network technologies and protocols, up to the construction of applications that benefit from all this infrastructure, supporting better public and environmental management and adding value to the citizen.

H.264 SBTVD network

Research network that has the Federal University of Rio Grande do Sul, as executor, in which Unicamp appears as co-executor, with Prof. Meloni as local coordinator. The network is financed by MCT in a FINEP project, where UNICAMP is responsible for the development of an audio decoder implemented in DSP adhering to SBTVD. The results obtained in this project are important in the design of an integrated circuit or digital receiver. The software encoder project is being developed on the network. This project is scheduled to end in December of this year.

Ginga Middleware Evaluation

Research network with CENPRA (CTI) as executor, in which Unicamp appears as co-executor, with Prof. Meloni. It had funding from MCT, in a FINEP project, where Unicamp worked on the evaluation of middleware in the area of teaching by digital TV, which resulted in the implementation of SW modules in a receiver turned to the market using a flash player. It made possible the execution of modules of the elementary education system called "Conexão do Saber", which was developed for the Web network and which can thus be evaluated in modern digital TV technology. Project results showed the enormous potential of this technology as an instrument of digital and social inclusion in the teaching area.

WiMAX-700 or WiMAX as Interactivity Channel for the Brazilian Digital Terrestrial Television System

The problem of access to computer resources in the digital age is a major challenge, especially for emerging countries. Digital TV is in itself an intrinsic convergence between television, the computer and the Internet. In addition to the improvement in video and audio quality achieved through efficient encoders, the fact that the system is digital requires the presence of a microprocessor that can perform the functions of a personal computer and provide applications of a social nature. The system needs a return channel that enables digital TV interactivity and creates a very rich environment that allows for various applications, such as distance learning, e-mail, Internet browser, e-commerce, instant messaging, chat, voting, e-government, health applications, etc. Such convergent technology has great potential to meet the first two objectives of Decree 4,901, of November 26, 2003, which created the Brazilian Digital Television System. The first objective of the decree is to promote social inclusion, cultural diversity in the country and the mother tongue through access to digital technology, aiming at the democratization of information. The second objective of the decree prays to create a universal distance education network. The use of digital TV in the area of ​​education can bring strong benefits to the countries of Latin America. The project aims to continue the SBTVD Interactivity Channel project, in which it was proposed to use WiMAX in operation below 1 GHz. The project proposes the continuity of research in the coexistence between the transmission system (broadcast) with a network of WiMAX / WiMAX-700 cell topology, with emphasis on the definitions of the WiMAX-700 specifications.

Interactivity Channel of the Brazilian Digital TV System

Research and Development of technological solutions for the interactivity channel of the Brazilian digital TV system. It involves studying and proposing a general model for the interactivity channel, R&D until the final phase of wireless solution prototypes through self-structured ad hoc networks, R&D until the final phase of wireless solution prototypes through networks structured wireless in-band RF, comparative studies of technological solutions for the interactivity channel and the final recommendations for the reference model. This FINEP project is a research consortium involving, in addition to researchers from Unicamp, the following institutions: Federal University of Rio de Janeiro, Institute for Advanced Communications Studies and the Foundation for Technological Innovations. The project also has the participation of three intervening co-financing companies: Linear Equipamentos Eletrônico, Samsung Development Institute for Informatics in the Amazon and Telecommunications in São Paulo.

Reference Middleware of the Brazilian Digital TV System

It is a Finep agreement for the research and development of a reference middleware for the Brazilian digital TV system. The project involves the proposal of middleware, the development of some resident applications, such as changing channels, user profiles, electronic mail and middleware extensions for distance learning. In the project it was possible to R&D two middleware methodologies: declarative and procedural. A declarative middleware application developed was an Internet browser for TV (browser). This inspired the name given to the consortium's middleware: Jangada. The agreement, in addition to the participation of Unicamp researchers, included the following institutions: Institute for Advanced Communications Studies, the State University of Londrina and the Foundation for Technological Innovations.
