  • Patent number: 11995375
    Abstract: This application discloses an audio stream switching method and apparatus. After a switching device receives a switching instruction, the switching device determines a synchronization relationship between a switch-in stream and a switch-out stream, determines a parameter value of a switching point of the switch-in stream based on the synchronization relationship and a timestamp of a packet in the switch-in stream, and determines a timestamp of a switching point of the switch-out stream based on the synchronization relationship and a timestamp of a packet in the switch-out stream, and/or the switching device switches a packet that is in the switch-out stream and whose parameter value is greater than the parameter value of the switching point of the switch-out stream to a packet that is in the switch-in stream and whose parameter value is greater than the parameter value of the switching point of the switch-in stream.
