Abstract

Embodiments of the present invention provide a method for synchronous playback by multiple smart devices, and an apparatus. A first device acquires frame synchronization information at intervals of a preset time, and sends the frame synchronization information to one or more second devices, where the frame synchronization information is frame information of a frame to be played by the first device or frame information of a frame that the first device starts to play currently; and after learning the frame synchronization information sent by the first device, the second device adjusts frame resources played by itself. Because the multiple smart devices that perform synchronous playback are generally in one local area network, a transmission delay of frame information from the first device to the second device can be ignored, thereby improving a synchronization effect among the multiple smart devices.
