The method is performed by a master device among multiple synchronous playback devices which further include at least one slave device that is used to play a same video file as the master device. The method includes: obtaining a first start playback time point of a to-be-played key frame of the video file, in the video file; and sending, at a first moment, a synchronization instruction to the at least one slave device. The synchronization instruction includes indicating that the first start playback time point is a target synchronization time point, the first moment corresponds to a first playback progress time point in the video file, and the first playback progress time point is located before the first start playback time point. The technical solution of the present disclosure can realize synchronous video playback among multiple devices, with low implementation cost and high synchronization accuracy."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for synchronously playing video among multiple devices","description":"The present disclosure provides a method and apparatus for synchronously playing video among multiple devices and belongs to the field of video playback technology.
