Abstract

técnicas são descritas para aumentar a confiabilidade de transferência de dados através de sinalização em banda em um canal de áudio em uma rede de comunicação. as técnicas incluem fazer com que um processo de decodificação de áudio modifique a decodificação de sinais de áudio para o canal de áudio com base na obtenção de uma indicação de sinalização em banda. a decodificação modificada pode substituir um buffer de-jitter adaptativo por um buffer de-jitter estático ou aumentar o tempo de armazenamento em buffer de um buffer de-jitter adaptativo. os sinais de áudio decodificados podem ser fornecidos para um detector de mensagens em banda, para um codificador de áudio ou para um dispositivo de reprodução de áudio com base na indicação de sinalização em banda. as técnicas podem ser empregadas por um equipamento de usuário, por uma função de controle de gateway de mídia ou por um gateway de mídia para melhorar a confiabilidade de transferência em banda de um conjunto de dados mínimo (msd) para uma ecall de próxima geração.
