Abstract

Se divulga un método y dispositivo de codificación de señal, el método incluye: en un caso en el cual una manera de codificación de una trama previa de una trama actualmente introducida es una manera de codificación continua, predecir un ruido de confort que es generado por un decodificador de acuerdo con la trama actualmente introducida en un caso en el cual la trama actualmente introducida es codificada en una trama SID, y determinar una señal de silencio real (210), donde la trama actualmente introducida es una trama de silencio; determinar un grado de desviación entre el ruido de confort y la señal de silencio real (220); determinar una manera de codificación de la trama actualmente introducida de acuerdo con el grado de desviación, donde la manera de codificación de la trama actualmente introducida incluye una manera de codificación de trama de retención o una manera de codificación de trama SID (230); y codificar la trama actualmente introducida de acuerdo con la manera de codificación de la trama actualmente introducida (240); se determina, de acuerdo con el grado de desviación entre el ruido de confort y la señal de silencio real, que la manera de codificación de la trama actualmente introducida es la manera de codificación de trama de retención o la manera de codificación de trama SID, lo cual puede ahorrar ancho de banda de comunicación.
