With continuous development of terminal technologies and internet of things technologies, a user has increasingly more types of intelligent electronic devices with increasingly more functions. These intelligent electronic devices have a data processing function and also have a communication function. In some possible implementation solutions, an intelligent multimedia playback device is an intelligent electronic device that can play multimedia content (for example, a picture, an audio, or a video), for example, a smart speaker, a smart television, a smart projector, smart VR glasses, or a smart vehicle-mounted display. The multimedia content is optionally stored in the intelligent multimedia playback device, or optionally shared by another intelligent electronic device and the intelligent multimedia playback device, or optionally obtained by the intelligent multimedia playback device from a server.
