Abstract
A video synchronous playback system includes: a mobile terminal, a personal computer (PC), an encoding server, a streaming server, and a playback device, where the mobile terminal is configured to capture a current displayed frame of a played video to obtain a first image, perform bitmap scaling processing on the first image to obtain a second image, perform image compression processing on the second image to obtain a third image, and send the third image to the encoding server by using the PC; and the encoding server is configured to restore the third image into a bitmap image to obtain a fourth image, perform bitmap scaling processing on the fourth image to obtain a fifth image, perform format conversion, encoding processing, and encapsulation on the fifth image to obtain a video stream, and send the video stream to a target playback device by using the streaming server.
