Description

technical field [0001] The invention relates to the field of interactive multi-screen, in particular to an intelligent interactive multi-screen. Background technique [0002] Multi-screen interaction Multi-screen interaction refers to the transmission of multimedia content between different terminal devices, such as common smart terminals, smart phones, TVs and other terminals, through WIFI network connection based on DLNA protocol or IGRS protocol. , display and a series of operations. Multi-screen interaction can share display content on different terminals at the same time, enriching the multimedia life of users. The common multi-screen interaction is the multi-screen collaboration function. The effect of screen operation, but it also has great limitations, for example: two devices can only display the same content at the same time and the interaction is poor, and they belong to different systems, which is not convenient for external signal input; cannot carry out three-...
