Abstract

métodos para codificar áudio de multicanal, para decodificar um fluxo de áudio de multicanal de taxa de bit variável sem perda e para iniciar decodificação de um fluxo de bit de áudio de multicanal de taxa debit variável, um ou mais meios legíveis por computador,um ou mais dispositivos semicondutores, e, decodificador de áudio de multicanal um codec de áudio sem perda codifica/decodifica um fluxo de bits de taxa de bit variável (vbr) sem perda com capacidade de ponto de acesso aleatório (rap) para iniciar decodificação sem perda a um segmento especificado dentro de um quadro e/ou capacidade de múltiplos conjuntos de parâmetro de predição (mpps) dividido para diminuir efeitos transientes. isto é realizado com uma técnica de segmentação adaptável que fixa pontos de começo de segmento baseado em constrangimentos impostos pela existência de um rap desejado e/ou transiente detectado no quadro e seleciona uma duração ótima de segmento em cada quadro para reduzir carga útil de quadro codificado sujeito a um constrangimento de carga útil de segmento codificado rap e mpps são particularmente aplicáveis para melhorar desempenho global para durações de quadro mais longas.
