Abstract

resumo "transcodificação de metadados". o presente documento refere-se à transcodificação de metadados, e em particular a um método e sistema para a transcodificação de metadados com complexidade computacional reduzida. um transcodificador configurado para transcodificar um fluxo de bits de entrada compreende um quadro de conteúdo de entrada e de um quadro de metadados entrada de associados em um fluxo de bits de saída que compreende um quadro de conteúdo de saída e um quadro de metadados de saída associado é descrito. o quadro de conteúdo de entrada é indicativo de um sinal codificado de acordo com um primeiro sistema de codec e o quadro de conteúdo de saída é indicativo do sinal codificado de acordo com um segundo sistema de codec. o transcodificador é configurado para identificar um bloco de entrada de metadados a partir do quadro de metadados de entrada, o bloco de entrada de metadados associado com um descritor de entrada indicativo de uma ou mais propriedades de metadados compreendidas dentro do bloco de entrada de metadados, e para gerar o quadro de metadados de saída a partir do quadro de metadados de entrada com base no descritor de entrada.
