“…O sistema adotado no Brasil é ISDB-TB, também conhecido por o SBTVD (Sistema Brasileiro de TV Digital) que foi desenvolvido a partir do padrão Japonês ISDB-T. Todo o sistema de transmissão e recepção é normalizado pela ABNT NBR 15601 -15608, porém as técnicas utilizadas e os algoritmos podem variar de acordo com o desenvolvedor [21].…”

Resumo-Este trabalho tem por objetivo analisar a interferência entre o sistema LTE (Long Term Evolution) e ISDB-TB (Integrated Services Digital Broadcasting Terrestrial version B) na banda de 700 MHz.Para a análise é determinada a distância mínima que assegura o funcionamento dos dois sistemas na gama de funcionamento. O impacto da interferência é avaliado em um cenário onde a estação de LTE, estação de TV digital e receptor de TV digital estão presentes na mesma área de cobertura.Usando os parâmetros apresentados neste trabalho é calculado a potência de interferência que chega ao receptor de TV digital de acordo com a distância da estação de LTE e receptor de TV digital.Além disso, o resultado também mostra que o filtro utilizado no receptor atenua a energia do sinal de LTE, e a distância entre a estação e o receptor de TV digital LTE diminui consideravelmente, o que permite uma interação entre os sistemas.Palavra Chave-LTE, 4G, ISDB-TB, Interferência, 700 MHz. Abstract-This work aims to analyze the interference between the LTE system (Long Term Evolution) and ISDB-TB (Integrated Services Digital Broadcasting Terrestrial version B) in the 700 MHz band.For analysis, the minimum distance is determined which ensures the operation of two systems in the operating range. The interference impact is evaluated in a scenario where the LTE station, digital TV station and digital TV receiver are present in the same coverage area. Using the parameters addressed in this paper, the interference power which arrives at the digital TV receiver is calculated according to the distance between the LTE station and the digital TV receiver.Furthermore, the result also shows that the filter used in the receiver attenuates the energy of LTE signal, and the distance between the station and the LTE digital TV receiver decreases considerably, permitting an interaction between the systems. Index Terms-LTE, 4G, ISDB-TB, Interference, 700 MHz.

Abstract-This paper is a survey of the transmission techniques used in digital television (TV) standards worldwide. With the increase in the demand for High-Definition (HD) TV, videoon-demand and mobile TV services, there was a real need for more bandwidth-efficient, flawless and crisp video quality, which motivated the migration from analogue to digital broadcasting. In this paper we present a brief history of the development of TV and then we survey the transmission technology used in different digital terrestrial, satellite, cable and mobile TV standards in different parts of the world. First, we present the Digital Video Broadcasting standards developed in Europe for terrestrial (DVB-T/T2), for satellite (DVB-S/S2), for cable (DVB-C) and for hand-held transmission (DVB-H). We then describe the Advanced Television System Committee standards developed in the USA both for terrestrial (ATSC) and for hand-held transmission (ATSC-M/H). We continue by describing the Integrated Services Digital Broadcasting standards developed in Japan for Terrestrial (ISDB-T) and Satellite (ISDB-S) transmission and then present the International System for Digital Television (ISDTV), which was developed in Brazil by adopteding the ISDB-T physical layer architecture. Following the ISDTV, we describe the Digital Terrestrial television Multimedia Broadcast (DTMB) standard developed in China. Finally, as a design example, we highlight the physical layer implementation of the DVB-T2 standard.

“…To overcome the problems we encountered, we performed an extensive literature survey on the related fields, conducted interviews with the domain experts from the company, and received continuous feedback from the experts, who constantly reviewed the evolving feature model. For the data collection step, we started by collecting information from the domain experts, product documentation, and publications on digital TVs [3]- [5]. This data were mainly a bunch of vague information for the people other than domain experts before we chose appropriate ones and extracted them as features.…”

Abstract-This paper presents a feature modeling endeavour for a television set product family by a major consumer electronics company. This work consists of three stages. First, a feature model is constructed, based on the analysis of the product family requirements. The constructed model is supplemented with a feature glossary. FeatureIDE is used as the model editor. Feature attributes, not supported by FeatureIDE, are represented in the basic feature model by using additional features. Second, the feature model in XML is converted into the schema of the analysis tool, using a custom parser developed for this purpose. Third, the model is analyzed by well-known analysis operations. FAMA is used as the analysis tool. Performance results are obtained. Finally, lessons learned from the whole effort are discussed.Index Terms-Feature modeling, extended feature model, software product lines, commonality, variability, variability management.
