Abstract: Provided is a method for detecting an audio input interface, comprising: acquiring input signals of every one of audio input interfaces; acquiring energy values of said input signals of every one of said audio input interfaces, and acquiring an interface identification of the audio input interface of which the energy value is the maximum among the energy values; adding said interface identification acquired herein into an identification sequence in an order by acquiring time; and identifying the audio input interface, of which the interface identification is saved most often in said identification sequence, as a valid audio input interface. Also provided is a system for detecting an audio input interface. The present disclosure is capable of effectively identifying the audio input interface connected to the microphone that the user is using, so that the user does not need to switch manually.

Abstract: Systems and methods are provided for data transmission. For example, packet loss is detected based on at least information associated with a first data packet; and in response to packet loss being detected, a packet-retransmission request is sent to a data-transmission terminal and the packet-retransmission request is repeatedly sent to the data-transmission terminal during a retransmission life-cycle associated with the first data packet, the packet-retransmission request including a first identification of the packet-retransmission request.

Abstract: A method, apparatus and system for acquiring an input event in a computer system comprising different priorities for processes are provided, the method comprising: executing a servant process and a master process, wherein the servant process comprises a higher priority than the master process and an input event list; and upon the servant process acquiring an input event and determining that the input event is in the input event list, the servant process transmitting the input event to the master process. A servant process with a high priority is used to acquire input events, which facilitates the operation of other processes and enhances process execution efficiency.
