Abstract

agrupamento adaptativo de parâmetros para maior eficiência de codificação. a presente invenção se baseia no achado de que os parâmetros que incluem um primeiro conjunto de parâmetros de uma representação de uma primeira porção de um sinal original e que incluem um segundo conjunto de parâmetros de uma representação de uma segunda porção do sinal original podem ser codificados de forma eficiente, quando os parâmetros são dispostos em uma primeira seqüência de tuplas e em uma segunda seqüência de tuplas, caracterizado pelo fato de que a primeira seqüência de tuplas compreende tuplas de parâmetros tendo dois parâmetros de uma única porção do sinal original e onde a segunda seqüência de tuplas compreende tuplas de parâmetros tendo um parâmetro da primeira porção e um parâmetro da segunda porção do sinal original. pode ser obtida uma codificação eficiente usando um estimador de bits para estimar o número necessário de bits para codificar a primeira e a segunda seqüências de tuplas, onde só a seqüência de tuplas é codificada, o que resulta em um menor número de bits.
