METHOD AND SYSTEM FOR MEASURING AUDIO TRANSMISSION DELAY

摘要

A method and a system for measuring an audio transmission delay are provided. Synchronization operation is performed on transmission of an original audio codebook to be tested between a transmitter and a receiver. A transmitter starts sending the original audio codebook to be tested to a receiver in response to sending start instruction information, and stops sending the original audio codebook to the receiver in response to sending end instruction information. The receiver starts capturing the original audio codebook from the transmitter in response to receiving start instruction information and stops capturing the original audio codebook from the transmitter in response to receiving end instruction information. The audio transmission delay is obtained based on a test audio codebook captured by the receiver and the original audio codebook pre-stored in the receiver.

1. A method for measuring an audio transmission delay, comprising:
performing synchronization operation on transmission of an original audio codebook to be tested between a transmitter and a receiver, to determine sending start instruction information, sending end instruction information, receiving start instruction information and receiving end instruction information of the original audio codebook; starting, by the transmitter, sending the original audio codebook to the receiver in response to the sending start instruction information; stopping, by the transmitter, sending the original audio codebook to the receiver in response to the sending end instruction information; starting, by the receiver, capturing the original audio codebook from the transmitter in response to the receiving start instruction information to obtain a test audio codebook; stopping, by the receiver, capturing the original audio codebook from the transmitter in response to the receiving end instruction information; and obtaining the audio transmission delay based on the test audio codebook captured by the receiver and the original audio codebook pre-stored in the receiver.
