Abstract

"MéTODO E APARELHO PARA TRANSMISSãO POR MULTIDIFUSãO DE INFORMAçõES". Trata-se de um método (400; 530), um aparelho e uma estrutura de dados (300) que permitem a recepção completa de datagramas por uma série de clientes (140) por meio de um mecanismo de transporte de multidifusão UDP, em que pacotes faltantes (310) são retransmitidos (536) de um servidor (110) por meio ou de um mecanismo de transporte de multidifusão ou de uma conexão de unidifusão, em resposta ao recebimento pelo servidor de um pedido de cliente de retransmissão (518, 528). A estrutura de dados de pacotes inclui um novo campo de identificadores de seq³ência no cabeçalho para identificação da posição de pacote apropriada dentro de um fluxo de dados.
