Abstract
A synchronous modulation method based on an embedded player. The method comprises the steps of: Step S1, acquiring a current timestamp adopted by a current synchronous audio signal and a current synchronous video signal; Step S2, acquiring a jump difference value of the current timestamp; Step S3, determining whether the jump difference value is less than a first preset time, if yes, synchronously playing, by the player, the audio signal and the video signal through a first timestamp, and exiting; and Step S4, determining whether the jump difference value is greater than a second preset time, if yes, synchronously playing, by the player, the audio signal and the video signal through a second timestamp, and exiting.
