Media Engineering

The LSI – TEC (NEM/LSI – TEC) Media Engineering Nucleus’ activities are directed to software and hardware multimedia research and development projects.

Its main goal is to be synchronous with multimedia technology developments, using its knowledge in significant socio-economical projects conjunctly with many communities and suggesting low-cost solutions  which are inserted in important strategic projects for  the national technological scenery, providing subsidy to governmental decisions of great social impact. With a highly equipped digital TV laboratory, the Nucleus action areas are: Multimedia platforms for accessing Digital Network Services, including Wireless Communication Technologies, Digital Media Compression and Encoding, Embedded Architecture Real-Time Operating Systems, Tridimensional View Systems (3D Visual Projection/3D auralization/3D surrounding), Music Technology (analysis/synthesis/musical computing), Viability Analysis for the Introduction of New Products, and Usability Analysis and Development of Interactive TV Applications.

In 2003, there was an intense debate regarding the Brazilian standards for Digital TV technologic definition and development. LSI -TEC has actively contributed to this debate, since its beginning, cooperating with the decision making process together with the Brazilian and transnational corporations established in Brazil.

LSI – TEC’s contributions have arisen from the Digital TV research line, the goal of which is to control the multimedia subsystems strategic technologies that are critical for the innovation leap planned by Brazil regarding Digital TV.

Since 2003, the SBTVD (Brazilian Digital TV System), managed by ten Government Departments and funded by FINEP / FUNTTEL, has been developed, and also involves
several universities from different Brazil’s states, as well as various national and transnational companies. The project included the Interactive TV Solutions study, Multimedia Encoding (video transport, mainly MPEG pattern) and the development of multimedia access terminals (the Set-Top boxes).

LSI-TEC has applied to participate in all official calls related to the SBTVD. In fact, it became directly responsible for coordinating and carrying out the three projects below: TAR (Terminal de Acesso de Referência, Reference Access Terminal), AVC (Codificador e Decodificador de vídeo AVC/H.264 – Advanced Video Coding) e AAC (Codificador e Decodificador de áudio AAC – Advanced Audio Coding/Decoding).

Among them, the TAR project is the main cause for success in creating a model that can be adapted to the low cost conditions; in addressing digital inclusion and in maintaining the crucial interaction requirements, and audio-visual content quality requirements. The results of this project have been consolidated on deliveries performed in December 2005, as a recommendation that approached the mobile, portable and fixed incoming conditions.
