Abstract

"MéTODO DE RENDERIZAçãO SIMULTâNEA DE MúLTIPLAS CORRENTES DE VìDEO CODIFICADAS, SISTEMA DE RENDERIZAçãO SIMULTâNEA DE MúLTIPLAS CORRENTES DE VìDEO CODIFICADAS, E DECODIFICADOR INTERATIVO PARA RENDERIZAçãO SIMULTâNEA DE MúLTIPLAS CORRENTES DE VìDEO CODIFICADAS". Um sistema e método para a transmissão e renderização simultâneas de múltiplas correntes de vídeo digitais em uma aplicação de televisão interativa são revelados. Transmissão e renderização simultâneas de múltiplas correntes de sinal de vídeo digital codificadas em uma aplicação de televisão interativa geralmente compreende modificar pelo menos uma das múltiplas correntes de vídeo codificadas difundidas a partir de uma central de difusão para reposicionamento da pelo menos uma das múltiplas correntes de vídeo codificadas para exibição (362), intercalando as múltiplas correntes de vídeo codificadas tendo a pelo menos uma corrente de vídeo codificada modificada em uma única corrente de vídeo intercalada composta (364), e emitindo a única corrente de vídeo composta. O método pode compreender adicionalmente a recepção de múltiplas correntes de vídeo codificadas provenientes de uma central de difusão. Cada uma das múltiplas correntes de vídeo codificadas é, de preferência, codificada pelo uso de tecnologia de compressão MPEG- 1 ou MPEG-2.
