A prestação de serviços de comunicação: conceito e limites para a sua tributação

Rabelo Filho, Antônio Reinaldo 21 December 2009 (has links)
Made available in DSpace on 2016-04-26T20:29:57Z (GMT). No. of bitstreams: 1 Antonio Reinaldo Rabelo Filho.pdf: 1182565 bytes, checksum: 04d7e2e5109cb7d7b401525d148c9d80 (MD5) Previous issue date: 2009-12-21 / The present study aims at ascertaining the specific aspects regarding the levying of the Tax on Communication Services, by means of distinguishing between the service communications tax s event of assessment s nucleus to provide communication services and other related conducts. Subsequently, we also analyze the tax system in order to outline the premises needed to comprehend the Tax on Communication Services event of assessment. By means of these studies, we conclude that to provide communication services , as said tax s event of assessment s nucleus, must be understood as the conduct of offering the necessary and sufficient conditions to transport a message. Furthermore, we define the concepts of radio broad-casting, publicity and paid television, in order to conclude that radio broad-casting is taxed by the Tax on Communication Services. Regarding to publicity and advertising, the tax doesn´t levy on their production but only on the service rendered for their transportation if it was the utility hired. However, we understand that paid television, when monthly paid for by its users, does not meet the necessary requirements to be levied by the Tax on Communication Services. Regarding the telecommunication services, we initiated our research with an overview of the Brazilian telecommunications system prior to the privatization process, which resulted in the General Telecommunications Law GTL. Afterwards, we focused on the utilities and features provided by not only the communication service providers, but also of those provided by third-parties. From this we noticed that when there is economic autonomy and private usage, put at the user s disposal by means of an affirmative obligation established in law, the correct event of assessment is that of the Service Tax. However, it is necessary to previously verify if it is something accessory and contemplated in the concept of offering the necessary and sufficient means of transporting messages from third-parties, in return for payment. If the answer is positive than the activity may be levied by the Tax on Communication Services. Lastly, we conclude that it is necessary to dissociate the utilities offered by means of the internet, or even cellular phones, from the concept of providing services, which is the event of assessment of the Tax on Communication Services and of the Service Tax, insofar as the assignment of the rights pertaining to a program or content, even if only on a temporarily basis, does not align itself with the conduct of executing said content or of transporting it to a third-party. In brief, we understand that the correct comprehension of each of the legal relationships displayed will give the interpreter the necessary instruments to define the applicable tax norms / O objetivo do presente trabalho é estabelecer os contornos específicos da regra-matriz de incidência tributária do imposto sobre prestação dos serviços de comunicação, a partir da diferenciação entre o conceito atinente ao núcleo da hipótese de incidência prestar serviços de comunicação e outras realidades por vezes conexas. Posteriormente, estudamos o sistema tributário e fixamos as premissas para a compreensão da regra-matriz de incidência tributária do ICMS-comunicação. A partir dessas considerações, concluímos que prestar serviço de comunicação , como núcleo da hipótese de incidência da referida exação, precisa ser entendido como a atividade de oferecer as condições necessárias e suficientes para que uma mensagem seja transportada. Mais adiante, definimos os conceitos de serviços de radiodifusão, publicidade e TV por Assinatura, para concluir que a prestação dos serviços de radiodifusão são tributados pelo ICMS-comunicação. Quanto ao serviços de publicidade e propaganda, o imposto não incide sobre a sua produção, mas sobre os serviços oferecidos para o seu transporte ou veiculação, se for essa a utilidade contratada. Para a TV por assinatura, remunerada via prestação mensal cobrada dos seus usuários, entendemos que a materialidade não reúne as notas suficientes para ser incluída no espectro de incidência do ICMS-comunicação. Sobre os serviços de telecomunicações, iniciamos nossa pesquisa com um escorço histórico acerca do sistema de telecomunicações brasileiro antes do processo de privatização, que culminou com a edição da Lei Geral das Telecomunicações LGT. Após, nos dedicamos a analisar o oferecimento de utilidades e funcionalidades não apenas por parte das próprias operadoras dos serviços de comunicação, mas também por terceiros. Com isso percebemos que, onde se vislumbrar autonomia econômica e utilidade própria, posta à disposição por intermédio da realização de um fazer prevista na legislação de regência, está-se diante da hipótese de incidência do ISS. Todavia, é necessário, antes, perceber se está-se diante de algo acessório e inserido no conceito de disponibilização dos meios necessários e suficientes para transporte de mensagens de terceiros, mediante pagamento. Se positiva a resposta, estaremos diante de realidade que pode ser tributada pelo ICMS. Por fim, concluímos que é preciso que se afaste do conceito de prestação de serviços, hipótese de incidência do ICMS ou do ISS, as utilidades oferecidas por meio da internet ou mesmo aparelhos celulares. Isso porque a cessão do direito de uso de um programa ou conteúdo, ainda que de forma temporária, não se compagina com a atividade de executar aquele conteúdo ou de transportá-lo a terceiro. Em resumo, entendemos que o correto entendimento de cada uma das relações jurídicas postas é que dará ao aplicador o cabedal necessário para a definição da norma tributária aplicável

Convergence of web and communication services

Shanmugalingam, Sivasothy 30 April 2012 (has links) (PDF)
Different communication services from delivery of written letters to telephones, voice/video over Internet Protocol(IP), email, Internet chat rooms, and video/audio conferences, immersive communications have evolved over time. A communication system of voice/video over IP is the realization of a two fundamental layered architecture, signaling layer and media layer. The signaling protocol is used to create, modify, and terminate media sessions between participants. The signaling layer is further divided into two layers, service layer and service control layer, in the IP Multimedia Subsystem (IMS) specification. Two widely used communication systems are IMS, and Peer-to-Peer Session Initiation Protocol (P2P SIP). Service providers, who behave as brokers between callers and callees, implement communication systems, heavily controlling the signaling layer. These providers do not take the diversity aspect of end users into account. This dissertation identifies three technical barriers in the current communication systems especially in the signaling layer. Those are: I. lack of openness and flexibility in the signaling layer for end users. II. difficulty of development of network-based, session-based services. III. the signaling layer becomes complex during the high call rate. These technical barriers hinder the end-user innovation with communication services. Based on the above listed technical barriers, the first part of this thesis defines a concept and architecture for a communication system in which an individual user becomes the service provider. The concept, My Own Communication Service Provider (MOCSP) and MOCSP system is proposed and followed by a call flow. Later, this thesis provides an analysis that compares the MOCSP system with existing communication systems in terms of openness and flexibility. The second part of this thesis presents solutions for network-based, session based services, leveraging the proposed MOCSP system. Two innovative services, user mobility and partial session transfer/retrieval are considered as examples for network-based, session-based services. The network-based, sessionbased services interwork with a session or are executed within a session. In both cases, a single functional entity between caller and callee consistently enables the media flow during the call initiation and/or mid-call. In addition, the cooperation of network call control and end-points is easily achieved. The last part of the thesis is devoted to extending the MOCSP for a high call rate and includes a preliminary comparative analysis. This analysis depends on four factors - scalability limit, complexity level, needed computing resources and session setup latency - that are considered to specify the scalability of the signaling layer. The preliminary analysis clearly shows that the MOCSP based solution is simple and has potential for improving the effective usage of computing resources over the traditional communication systems

Customer Integration und Customer Governance – Neue Konzepte für die Anbieter-Kunden-Beziehung im B2C-E-Business

Robra-Bissantz, Susanne, Lattemann, Christoph 15 December 2014 (has links) (PDF)
Das Internet mit immer neuen Kommunikationsdiensten hat das Potenzial, völlig neue Strategien des Unternehmens an der Schnittstelle zu seinen privaten Kunden einzuleiten. Der Kunde nimmt in Zukunft nicht mehr allein die Rolle eines passiven Käufers ein [Homburg, Gruner 96]. Stattdessen entwickelt er sich zu einem aktiven Partner des Unternehmens, was potenziell zu einer neuen Gestaltung der Unternehmensorganisation führt sowie zu neuen strategischen Optionen, z. B. zur Generierung von Wettbewerbsvorteilen. Ein Beispiel dieser Entwicklung ist die Customer Integration, die Einbindung des Kunden als Co-Worker in Wertschöpfungsprozesse eines Unternehmens.

A tributação da contraprestação paga pelo uso da imagem de artistas e esportistas / The taxation in consideration paid to entertainers and sportspeople for the image right license granted

Marcondes, Rafael Marchetti 23 February 2016 (has links)
Made available in DSpace on 2016-04-26T20:24:14Z (GMT). No. of bitstreams: 1 Rafael Marchetti Marcondes.pdf: 1161112 bytes, checksum: 4745ef914408134f883713606c3519d9 (MD5) Previous issue date: 2016-02-23 / This work aims to examine taxation on compensation received by entertainers and sportspeople for the license granted to third parties to use their image rights. Current legislation approaches the matter in a generic way, either equating the use of an image right to a simple obligation to use or to an obligation to give or even not specifically regulating the subject. Therefore, we will present an investigative method by means of which it is possible to consistently decide whether or not to levy taxes in such operations. The proposal herein is to start examining the transaction concerning the use of an image by identifying the main activity agreed in order to subsequently evaluate if such rendering implies an obligation whose legal nature is either to do or to give. The conclusion for charging or not the various taxes will result from the comparison between each tax s material aspect and the legal nature of the analyzed obligation. Notwithstanding, we aim to previously define the characteristic features of personality rights, especially image rights, in order to be able to indicate the constitutional protection provided to the image in its several aspects: social image, sole external image and group external image, differentiating them from arena rights. The purpose is also to analyze distinctive features of the image, which make it a sole and unique right, as well as its legal nature from the several theories developed by the doctrine so as to define the parameters of the image. It is only after the abovementioned definition that this work will effectively examine the compensation gained by the image rights holder. The identification of the main activities involved and their legal nature will allow one to decide on the subsumption of facts concerning the use of the images of entertainers and sportspeople to the following taxes: Municipal Tax on Services (ISS), State Tax on Distribution of Goods, Transport and Communication Services (ICMS), Income Tax (IR), Social Contribution on Net Profits (CSL), Contribution for the Social Integration Program (PIS) and Contribution for the Financing of Social Security (COFINS), Contribution for Economic Intervention Royalties (CIDE-royalties) and Import and Export Duty. By examining the taxation by Income Tax, we will also analyze the possibility of entertainers and sportspeople to constitute legal entities aiming to exploit personal rights and the situations in which it is accepted to disregard the corporate entity. Finally, the paper will address the taxation regime applicable to international transactions comprising the use of the image of those entertainers and sportspeople, in situations which the purpose is an obligation to do and in those in which the purpose is an obligation to give, in compliance with OECD Model Convention and the treaties signed by Brazil in order to avoid double taxation / O trabalho tem por objetivo examinar a tributação da contraprestação recebida por artistas e esportistas em decorrência da licença concedida a terceiros para o uso do direito sobre a sua imagem. Como a legislação existente trata do assunto de forma genérica, ora equiparando a sua utilização a uma obrigação de fazer, ora a uma obrigação de dar, ou mesmo não regulando especificamente a matéria, apresentamos um método investigativo pelo qual é possível concluir com consistência pela incidência ou pela não incidência dos tributos nessas operações. A proposta aqui trazida é a de se examinarem os negócios que envolvam a utilização da imagem a partir da identificação da atividade-fim contratada, para, posteriormente, avaliar se tal prestação consiste em uma obrigação cuja natureza jurídica é de um fazer ou de um dar. A conclusão pela cobrança ou não das espécies tributárias decorrerá do confronto da materialidade de cada uma delas com a natureza jurídica da obrigação analisada. Antes, porém, vamos fixar os traços característicos dos direitos da personalidade e, em especial, do direito de imagem, passando a apontar a tutela constitucional conferida à imagem nas suas diferentes vertentes: atributo, retrato e retrato em obras coletivas, diferenciando-as do direito de arena. Também serão analisados os traços caracterizadores da imagem, que a tornam um direito único e singular, bem como a sua natureza jurídica a partir das diversas teorias desenvolvidas pela doutrina, a fim de delinear os contornos da imagem. Somente após isso é que o estudo passará efetivamente a examinar a contraprestação auferida pelo detentor da imagem, com base na identificação das atividades-fim envolvidas e sua natureza jurídica para concluir pela sujeição ou não dos fatos envolvendo o uso da imagem de artistas e esportistas ao ISS, ao ICMS, ao IR, à CSL, ao PIS e à COFINS, à CIDEroyalties, ao Imposto de Importação e ao de Exportação. Ao se examinar a tributação pelo IR, também será analisada a possibilidade de artistas e esportistas constituírem pessoas jurídicas com a finalidade de explorar direitos personalíssimos e as situações em que se admite a desconsideração da personalidade jurídica. Por fim, o estudo abordará o regime jurídico tributário aplicável às transações internacionais envolvendo o uso da imagem de artistas e esportistas, nas situações em que o fim pretendido é um fazer e naquelas em que ele consiste em um dar, diante do disposto na Convenção Modelo OCDE e nos tratados firmados pelo Brasil para evitar a dupla tributação da renda
