Scientific Academic Panel – Morning Edition

This panel will present a set of scientific papers that have been submitted to the Call for Papers promoted annually by SET. The selected works will be published in the SET International Journal of Broadcast Engineering (SET IJBE) an international scientific journal whose objective is the diffusion of knowledge on communications engineering, especially of the broadcast areas and new media. The SET IJBE search current research that comprise the state of the art of these technologies.

Social mobilization as a tool to support the switch off of TV and humanization of the process: the experience of Seja Digital in the Brazilians cities of the Rio Verde and Brasília.

This lecture shares the process of building the social mobilization experience of Seja Digital, a nongovernmental entity responsible for operationalizing the migration process for the digital TV signal in Brazil and the switch off. The Seja Digital promotes various actions to raise awareness and involve community, political and religious leaders in their campaigns, while encouraging them to develop tools and solutions within the communities where they live.

Speaker: Deisy Fernanda Feitosa - Regional Manager - Seja Digital

Graduated in Social Communication (UFPB), master in Digital TV (Unesp) and doctor (2015) in Communication Sciences (ECA / USP). She was a researcher at Lavid/UFPB and worked at Univesp TV, TV Cultura's multiprogramming channel. He currently works at Seja Digital, the company that manages the digitization of TV in Brazil. For eleven years he has been studying: digital TV, digital convergence and digital inclusion.

Robustness against the effects of multipath in an ISDB-T LDM broadcast system using diversity at reception

This presentation will show the development and results for the simulations of the ISDB-T LDM system, with the Core Layer fully compatible with the traditional ISDB-T and the Enhanced Layer using the Non-Uniform Constellation 64-QNUC, in order to improve spectral efficiency, performance, robustness and useful bit rate, so that it is possible to use it for UHDTV applications. In order to reach these goals, in addition to the LDM technique, the LDPC encoder/decoder concatenated with the BCH were used. The SDR/GRC implementation was used and the reception diversity was achieved by the use of the MRC method. The tests were performed using the proposed system in environments with AWGN and multipath channels. With the use of the ISDB-T LDM system using diversity at reception it was possible to achieve gains for all the tested configurations.

Speaker: Ricardo Seriacopi Rabaça - Researcher - Universidade Presbiteriana Mackenzie

Ricardo Seriacopi Rabaça received his degree in Electrical Engineering with emphasis in Electronics and Telecommunications from Mackenzie Presbyterian University in 2013. He received his M.S. degree in Electrical Engineering and Computation from Mackenzie Presbyterian University in 2017. He is interested in research in the areas of Telecommunications, Broadcasting and Software Defined Radio.

A Technical Study on the Transmission of HDR Content over a Broadcast Channel

High Dynamic Range Television is a topic of current interest in academia and industry since can attribute the same level of realism without the need to increase the resolution. The reference end-to end HDR system is based on HDR10 System due to its encoding efficiency and visual quality. However, it cannot be directed apply for the current Standard Dynamic Range
television system. This paper makes a technical study about the system requirements to be considered for transmitting a HDR service in broadcast television and presents objective metrics in different coding scenarios regarding the HDR10 System and a
subjective assessment of the generated tone-mapped videos.

Speaker: Diego Arturo Pajuelo Castro - researcher - Unicamp

Diego Arturo Pajuelo Castro is a doctoral student at the Department of Communications (DECOM) of the Faculty of Electrical Engineering and Computation (FEEC) of the State University of Campinas (Unicamp) and works as a researcher at the Visual Communications Laboratory (LCV). He worked for a number of years at one of Peru's leading Network Operations Centers (NOC), Telefonica, which provides digital television services to the Latin American Region. Currently, his research interests are in the area of ​​new technologies for television and multimedia systems and as part of the master's dissertation he has presented a Video Encoding Proposal for High Dynamic Range (HDR) Television System.

Development and Optimization of Antennas for HDTV Reception

The development and optimization of antennas for reception of high-definition digital television (HDTV) will be presented. It will be discussed as was possible to develop the antennas in an efficient way without the need of very complex calculations through an iterative method using a software based on finite elements for simulations. Comparisons are made with respect to the main parameters related to these antennas in order to establish a better choice both from a technical and economic point of view.
