Abstract

um sistema e método para a realização de vídeo telefonia são descritos. em um exemplo, é fornecido um aparelho possuindo um transceptor (550) configurado para receber (506, 520) dados e informação de vídeo telefonia indicando uma comutação (514) de um primeiro monitor para um segundo monitor a partir de uma rede (565). o aparelho também inclui um decodificador (560) acoplado de forma operacional ao transceptor e configurado para decodificar os dados de vídeo telefonia, uma memória compreendendo um armazenador de imagem codificada configurado para armazenar os dados de vídeo telefonia decodificados, e um processador acoplado de forma operacional ao transceptor, ao decodificador e à memória. o processador é configurado para, em resposta ao recebimento da informação indicando uma comutação de um primeiro monitor para um segundo monitor, instruir o transceptor a transmitir uma solicitação (518) de um quadro i para a rede.
