Abstract
método de codificação de fluxos de dados de vídeo baseado em grupos de imagens (gop) utilizadas em codificação de vídeo para definir a ordem segundo a qual são dispostas as imagens de codificação interna e de codificação preditiva que permitem gerar uma imagem visível, incluindo meios de correção de erros de transmissão por redundância, para transmissões através de uma rede sem fio controlada por um protocolo de comunicação de dados local. o fluxo de vídeo é constituído por pacotes g de dados sucessivos, cada pacote g compreendendo um primeiro conjunto m contendo os dados de vídeo a serem transmitidos, e por um segundo conjunto contendo dados de redundância obtidos através de um algoritmo de redundância. de acordo com o método, o primeiro conjunto de dados m é constituído por todos os dados de pelo menos um grupo de imagens (gop).
