SCIENTIFIC ACADEMIC PANEL – AFTERNOON EDITION

This panel will present in this afternoon edition another 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.

Novel UWB Antenna for Broadcasting Television System

This speech presents a ultra-wideband (UWB) discone antenna with a omnidirectional radiation pattern for use in broadcasting television system. Because it is an ultra-wideband antenna and has a omnidirectional radiation pattern making possible the use of a single antenna for receiving of TV signals from several transmitting stations in several geographic locations. The UWB antenna proposed in this work cover the frequency range from 320 MHz to 1.65 GHz with a gain of 1.7 dB and work in indoor and outdoor environments.

Digital TV Signal Reception and Amplification System

In this presentation we will present the development of an amplification system and two antennas for the reception of digital TV signals. The proposed antennas were based on the half-wave (λ/2) dipole topology with meander line geometry (MLA) and magnetic loop antenna. Simulations were performed using software based on the finite element method. The reception of the antenna and the efficiency of the amplification system were evaluated through measurements.

Crowdfunding journalism

The proposal is to discuss innovation in journalism from the analysis of crowdfunding. This proposal is justified because it is a recent practice under construction and due to the lack of analysis based on theories that extrapolate studies in communication. An exploratory research was carried out from bibliographic research. Among the results achieved, it was found that crowdfunding is a promising innovation for the production of content.

COMPUTATIONAL SIMULATION PERFORMANCE BASED IN HYBRID MODEL FOR BROADCASTING SYSTEMS

With the objective of improving the transmission of information in broadcasting systems, in simulation environment, was implemented a model based on discrete events applied at a low level of abstraction in a telecommunication system. The proposal brings a different approach of usual technical, in which the signal transmission on the channel is realized in the discrete domain with the implementation of discrete entities in the process of bit generation.

Reasons for SFN Failure in Broadcast

To deliver the content of a TV network, ensuring efficient spectrum usage, filling not covered and shadow areas, and with energy savings are the advantages of Single Frequency Networks. Thus, in this study we sought to measure information, frequency, and time synchronism to evaluate the status of SFN implementation in Brazilian broadcasting. We took as base of analysis the Digital TV stations of the Campinas/SP area. Through this presentation, we demonstrate that one of the great advantages of ISDB-Tb, the formation of a single frequency network, still cannot be implemented in Brazil.

Dual-Polarized Indoor Antenna for Digital TV Reception

We will introduce the design and simulations of a dual-polarized antenna for digital television signal reception. The objectives of the project were low cost, simple construction and computational implementation for indoor applications and with good performance in terms return loss within the desired frequency band. Through the simulations, it was verified that the proposed antenna radiates two linear polarizations, horizontal and vertical, from the two feeding ports with a high degree of isolation. The structure developed in this work presents an omnidirectional irradiation pattern, gains over 4 dB in both polarizations, 390 MHz of bandwidth and 72.5% of fractional bandwidth.

It will be presented a technique of TS generation (Transport Stream) by software, intended for transmission with Digital TV signal generator according to the ISDB-Tb standard. In addition, it will be discussed how this TS was used for transmission and performed an analysis of the performance of BER (Bit Error Rate) in the reception for different communication channels, varying transmission parameters of the ISDB-Tb standard. The analysis was done through the Eb / No ratio by BER from the results obtained for each configuration.
