Video synchronous playback method, apparatus, and system

A video synchronous playback method, comprising:

• capturing, by a mobile terminal, a current displayed frame of a played video to obtain a first image, the first image being a first bitmap image;
• performing bitmap scaling processing on the first image according to a current resolution of the mobile terminal to obtain a second image;
• performing image compression processing on the second image to obtain a third image;
• sending the third image from the mobile terminal to an encoding server;
• receiving the third image by the encoding server;
• restoring, by the encoding server, the received third image, into a second bitmap image to obtain a fourth image;
• performing bitmap scaling processing on the fourth image according to a preset resolution to obtain a fifth image;
• performing format conversion, encoding processing, and encapsulation on the fifth image to obtain a video stream;
• and
• sending the image video stream to a target playback device.

An encoding server, comprising:

• an interface configured to receive a first video image that has been bitmap scaled by a mobile terminal to form second image and compression processed by a mobile terminal to form a second image:
• and one or more processors executing instruction modules, the instruction modules comprising:
• a restoring module, configured to restore a received third image, into a bitmap image to obtain a fourth image;
• a bitmap scaling module, configured to:
• after the restoring module obtains the fourth image, perform bitmap scaling processing on the fourth image according to a preset resolution to obtain a fifth image;
• a processing module, configured to:
• after the bitmap scaling module obtains the fifth image, perform format conversion, encoding processing, and encapsulation on the fifth image to obtain a video stream;
• and
• a video stream sending module, configured to:
• after the processing module obtains the video stream, send the video stream to a target playback device.
