或者，第一操作可以是用户通过语音输入功能输入“接听”指令，接听视频电话的操作。
又或者，用户还可以通过其他方式选择接听视频电话。任何用户执行的选择接听视频电话的操作均可视为第一操作。
基于该场景，相比较于现有技术中，当激光投影设备需要显示视频电话时，上述视频电话需要覆盖在激光投影设备的技术方案，本申请实施例提供的显示系统及显示方法能够将视频电话显示在第一微投设备上，从而避免视频电话遮挡激光投影设备的播放画面，提高用户的观看体验。
一种可能的实现方式中，多媒体控制器还可以通过生成显示器选择提醒信息，提醒用户选择显示视频通话信息的设备。
在该实现方式中，多媒体控制器确定的显示器选择提醒信息为第二信息，并向第一微投设备发送该显示器选择提醒信息。第一微投设备显示该显示器选择提醒信息。
在多媒体控制器接收到用户设备选择第一微投设备显示视频通话时，多媒体控制器确定视频通话为第二信息。
在多媒体控制器接收到用户设备选择激光投影设备显示视频通话时，多媒体控制器确定该视频通话为第一信息。相应的，多媒体控制器可以确定当前激光投影设备正在播放的视频为第二信息，将其发送至微投设备进行播放。
基于此，显示系统可以基于用户的选择，灵活的确定显示视频播放的设备和播放视频通话的设备。
