In an embodiment of the present application, the method further includes: when a trigger condition is monitored, acquiring a first playing progress corresponding to a screen projection picture displayed by the first target device and a second playing progress corresponding to audio data played by the second target device; and sending an adjusting instruction for adjusting the playing progress of the audio data to the second target device under the condition that the first playing progress and the second playing progress are not synchronous so as to synchronize the screen projection picture and the playing progress of the audio data.
The terminal device may obtain a first playing progress corresponding to a screen projection picture displayed by the first target device and a second playing progress corresponding to audio data played by the second target device when monitoring the triggering condition, and then compare whether the first playing progress and the second playing progress are synchronous, where the synchronization may be that a difference between the playing progresses of the first playing progress and the second playing progress is smaller than a preset threshold. For example, the first playing progress is 80%, the second playing progress is 79.99%, and the difference between the first playing progress and the second playing progress is less than 0.1%, it can be determined that the first playing progress and the second playing progress are synchronous; or, if the first playing progress is 20 minutes and 30 seconds, the second playing progress is 20 minutes and 32 seconds, and the difference value between the first playing progress and the second playing progress is greater than 1 second, it is determined that the first playing progress and the second playing progress are asynchronous. That is, the preset threshold may be a percentage or a duration.
The terminal device may periodically obtain the first playing progress and the second playing progress, and trigger the detection of whether the playing progress is synchronous or not based on time, where in this case, the trigger condition is time, for example, synchronous detection is performed every 5 minutes. The terminal equipment can also determine to monitor the trigger condition when the audio data or the screen projection picture is played to the preset progress. It may also be determined that the trigger condition is monitored when the terminal device receives a specific input from the user.
Under the condition that the first playing progress and the second playing progress are synchronous, no processing is needed; and under the condition that the first playing progress and the second playing progress are not synchronous, sending an adjusting instruction for adjusting the playing progress of the audio data to the second target equipment, so that the second target equipment adjusts the playing progress according to the adjusting instruction, and the synchronization of the screen projection picture and the playing progress of the audio data is ensured.
When an adjusting instruction for adjusting the playing progress of the audio data is sent to the second target device, if the first playing progress is greater than the second playing progress, an adjusting instruction for indicating fast forward of the audio data is sent, and if the first playing progress is less than the second playing progress, an adjusting instruction for indicating fast backward of the audio data is sent, and the adjusting instruction can carry the fast forward or fast backward degree, that is, which position the audio data needs to be fast forward or fast backward can be determined according to the adjusting instruction.
