Abstract

"MéTODO E SISTEMA PARA INTEROPERAR A PRIMEIRA ESTAçãO USANDO O PRIMEIRO ESQUEMA DE COMUNICAçãO, CODIFICADOR E DECODIFICADOR DE FALA, MéTODO PARA EXECUTAR A FUNçãO DE INTEROPERABILIDADE DA INTERFACE DO SISTEMA, E, PROGRAMA DE COMPUTADOR". Método e dispositivo para interoperar a primeira estação usando o primeiro esquema de comunicação e compreendendo o primeiro codificador e o primeiro decodificador com a segunda estação usando o segundo esquema de comunicação e compreendendo o segundo codificador e o segundo decodificador, a comunicação entre a primeira e a segunda estações é conduzida ao transmitir os parâmetros de codificação de sinal relacionados ao sinal de som do codificador de uma das primeira e segunda estações para o decodificador de outra estação. O sinal de som é classificado para determinar se os parâmetros de codificação de sinal deveriam ser transmitidos do codificador de uma estação para o decodificador de outra estação usando o primeiro modo de comunicação, no qual a taxa de bit máxima é usada para transmitir os parâmetros de codificação de sinal. Quando a classificação do sinal do som determina que os parâmetros de codificação de sinal deveriam ser transmitidos usando o primeiro modo de comunicação e quando um pedido para transmitir os parâmetros de codificação de sinal do codificador de uma estação para o decodificador de outra estação usando o segundo modo de comunicação designado para reduzir a taxa de bit durante a transmissão dos parâmetros de codificação de sinal for recebido, uma parte dos parâmetros de codificação de sinal do codificador de uma estação é distribuída e o restante dos parâmetros de codificação de sinal é transmitido para o decodificador de outra estação usando o segundo modo de comunicação. A parte distribuída dos parâmetros de codificação de sinal é regenerada antes do decodificador de outra estação decodificar os parâmetros de codificação de sinal.
