Abstract
"MéTODO PARA MODIFICAR DADOS EM UM SINAL DE DADOS CODIFICADO, DISPOSITIVO DE TRANSCODIFICAçãO PARA ADICIONAR DADOS A UM SINAL DE DADOS CODIFICADO, E, PRODUTO DE PROGRAMA DE COMPUTADOR PARA UM DISPOSITIVO DE TRANSCODIFICAçãO". A invenção relaciona-se a um método para modificar dados em um sinal de dados codificado (128) correspondendo a imagens sucessivas divididas em sub-imagens, para prover um sinal de dados modificado de saída (129). Em particular, a invenção pode ser usada para a inserção de um sinal de dados adicional (130) em um sinal de dados de vídeo comprimido (128). Os arranjos/diagramas propostos de acordo com a invenção são baseados em um arranjo de transcodificador que inclui pelo menos meio de decodificação parcial e meio de recodificação parcial. Este método conduz a uma solução efetiva em custo comparada com a técnica anterior incluindo um número mínimo de sub-etapas de DCT/IDCT, tirando vantagem de simplificações e combinações entre sub-etapas diferentes. Usa inserção de dados em um sinal de vídeo codificado.
