Abstract: A method implemented by a communication system, including at least a first electronic device and a second electronic device, includes that the first electronic device plays multimedia content. The first electronic device sends first synchronization information through broadcast, so that the second electronic device receives the first synchronization information, where the first synchronization information includes at least a first address, and the first address is an obtaining address of the multimedia content. In response to a preset operation, the first electronic device establishes a near field wireless communication connection to the second electronic device, and the second electronic device caches the multimedia content based on at least the first address. The first electronic device sends a control instruction to the second electronic device by using the near field wireless communication connection. The second electronic device plays the multimedia content based on the control instruction.

Abstract: An electronic device calculates an activeness ranking of all video call members based on factors such as a lasting time of a target sound intensity of a video call user within preset duration and an average value of sound intensities, and when a video call member in a non-display window is ranked higher than a video call member in a display window in the activeness ranking, interchanges the video call member in the non-display window with the video call member in the display window. A maximum interchange quantity L is set to limit a quantity of interchanges.
