Abstract
"APARELHOS PARA CODIFICAR E PARA DECODIFICAR UM SINAL DE INFORMAçãO, PROCESSO PARA REALIZAR UMA CODIFICAçãO DE UM SINAL DE INFORMAçãO E SUPORTE DE GRAVAçãO". Para "Super áudio CD" (SACD) os sinais DSD são codificados sem perdas, utilizando enquadramento, predição e codificação de entropia. Além dos sinais eficientemente codificados, um grande número de parâmetros, isto é, as informações colaterais, tem de ser armazenadas no SACD também. As informações colaterais compreendem os coeficientes de filtro de predição e a tabela de probabilidade que foi usada para codificação, e que deve ser transmitida para o decodificador. Tanto menor é a capacidade de armazenamento que é requerida para as informações colaterais, tanto melhor é o ganho de codificação global. Por conseguinte, técnicas de codificação são aplicadas às informações colaterais também de modo a compactar a quantidade de dados das informações colaterais. Os quadros podem ser segmentados, cada segmento tendo seu próprio conjunto de coeficientes de filtro e tabela de probabilidade.
