Abstract
"MéTODO E SISTEMA PARA REPARAR OS DADOS NAS COMUNICAçõES PONTO-PARA-MúLTIPLOS PONTOS, PRODUTO DE CóDIGO DE COMPUTADOR, E, DISPOSITIVO TRANSMISSOR". Método, sistema, dispositivo, e produto de código de computador são descritos, nos quais o transmissor (10) transmite os dados para uma pluralidade de receptores (20) através da sessão ponto-para-multipontos. O receptor envia os pedidos de reparo de dados para o transmissor (10) solicitando os dados esperados mas não recebidos e o transmissor (10) retransmite os dados esperados mas não recebidos através da sessão ponto-para-multipontos. O transmissor (10) pode também programar as sessões de reparo de dados ponto-a-ponto com receptores individuais se a retransmissão através da sessão de ponto-para-multipontos não corrige todos os erros. O transmissor (10) pode ser configurado para retardar as sessões de reparo ponto-a-ponto usando um mecanismo randómico baseado no número de receptores usando a sessão ponto-para-multipontos.
