Abstract
resumo “método e aparelho para medição da qualidade de vídeo” a precisão e a eficiência de medição da qualidade de vídeo são os proble-mas principais a serem solucionados. de acordo com a invenção, um método (506) para prever precisamente a qualidade de vídeo usa uma função racional do parâme-tro de quantização qp, que é corrigido por uma função de correção que depende da imprevisibilidade de conteúdos cu. de modo exemplificador, a função de correção é uma função poderosa da cu. tanto qp como cu podem ser computados (511) a partir do fluxo elementar de vídeo, sem decodificar completamente o vídeo. isso ga-rante alta eficiência.
