diferentes, dando a sensação de que os interlocutores encontram-se no mesmo local. Permite não só a comunicação entre um grupo, mas também a comunicação pessoa-a-pessoa. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Arquitetura">Arquitetura</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Videoconfer%C3%AAncia&veaction=edit&section=1" title="Editar secção: Arquitetura" class="mw-editsection-visualeditor"><span>editar</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Videoconfer%C3%AAncia&action=edit&section=1" title="Editar código-fonte da secção: Arquitetura"><span>editar código-fonte</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Essa comunicação é feita em tempo real e existem vários sistemas interpessoais de videoconferência que possibilitam isso. Além da transmissão simultânea de áudio e vídeo, esses sistemas oferecem ainda recursos de cooperação entre os usuários, compartilhando informações e materiais de trabalho. Em geral os equipamentos de videoconferência (terminais ou CODECs) disponíveis no mercado possuem capacidade de estabelecer uma comunicação ponto a ponto, e para que vários pontos se conectem simultaneamente é preciso utilizar um equipamento denominado MCU (<a href="/wiki/Multiponto_Control_Unit" class="mw-redirect" title="Multiponto Control Unit">Multiponto Control Unit</a>). O funcionamento da MCU assim como de outros componentes necessários a videoconferência são especificados pelo padrão <a href="/wiki/H.323" title="H.323">H.323</a> e <a href="/wiki/SIP" class="mw-redirect mw-disambig" title="SIP">SIP</a>. Também é possível estabelecer uma conexão entre varios pontos utilizando a tecnologia de conexão <a href="/wiki/Multicast" title="Multicast">Multicast</a>. O Multicast é pouco utilizado por ser uma tecnologia de rede que não esta presente na Internet apenas em redes privadas e fechadas. </p><p>Um ambiente comum de videoconferência é composto de uma sala dotada de uma câmera especial e alguma facilidade tecnológica para a apresentação de documentos. Atualmente, com o avanço dos <a href="/wiki/Processadores" class="mw-redirect mw-disambig" title="Processadores">processadores</a> (cada vez mais rápidos) e a <a href="/wiki/Compress%C3%A3o" class="mw-disambig" title="Compressão">compressão</a> de dados, surgiu um novo tipo de videoconferência, a conferência desktop. Nela não é necessário salas especiais e muito menos equipamentos ultra modernos: a interação é feita por uma <a href="/wiki/Webcam" title="Webcam">webcam</a> e um <a href="/wiki/Microfone" title="Microfone">microfone</a> simples.

Se necessita realizar videoconferências com mais de dois participantes que se encontram em locais distintos, nesse caso necessita de um sistema multiponto, conhecido também como MCU (do inglês <a href="https://en.wikipedia.org/wiki/Multipoint_control_unit" class="extiw" title="en:Multipoint control unit">Multipoint Control Unit</a>). A função principal consiste em gerir a videoconferência nos diferentes terminais. Em geral cada porta do MCU atua como uma interfaz de rede à qual se conectam os dispositivos que desejam participar na videoconferência. </p><p>Existem MCUs que são puros software, e outros que são a combinação de  hardware and software. O MCU caracteriza-se pelo número de chamadas em simultâneo e a capacidade de transmitir dados e protocolos que podem ser vistos no ecrã por todos os participantes. </p><p>No caso das videoconferências entre apenas dois pontos distintos, ou seja, podem ser vários participantes, mas apenas dois locais de comunicação diferentes, nesse caso o sistema a utilizar será o ponto a ponto. </p> <div class="mw-heading mw-heading2"><h2 id="Modos_de_videoconferência"><span id="Modos_de_videoconfer.C3.AAncia"></span>Modos de videoconferência</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Videoconfer%C3%AAncia&veaction=edit&section=5" title="Editar secção: Modos de videoconferência" class="mw-editsection-visualeditor"><span>editar</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Videoconfer%C3%AAncia&action=edit&section=5" title="Editar código-fonte da secção: Modos de videoconferência"><span>editar código-fonte</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Os sistemas de videoconferência usam vários modos de operar: </p> <ol><li>Switch ativado pela voz (do inglês Voice-Activated Switch - VAS);</li> <li>Presença contínua (do inglês) Continuous Presence</li></ol> <p>No modo VAS, o MCU switches do ponto (participante) que fala pode ser visto pelos outros pontos (participantes).
