Abstract

SISTEMAS E MéTODOS PARA A CODIFICAçãO E A DECODIFICAçãO DE FORMA ESCALONáVEL DE DADOS. Sistemas e métodos para a codificação e a decodificação de forma escalonável de dados codificados são apresentados. Um método de exemplo para a codificação de forma escalonável de dados inclui uma classificação, com base em pelo menos um critério predeterminado, cada um da pluralidade de dados recebidos como (i) dados perceptivamente relevantes ou (ii) dados perceptivamente irrelevantes. Os dados perceptivamente relevantes são codificados de forma escalonável e os dados perceptivamente irrelevantes são codificados de forma não escalonável. Subseqüentemente, os dados perceptivamente relevantes codificados de forma escalonável e os dados perceptivamente irrelevantes codificados de forma não escalonável são combinados em um fluxo de dados codificados para transmissão.
