Fuente: Wipo "IOT" The invention discloses a switching method of multi-way input and multi-way output of the Home-IOT and an interchanger. The switching method includes the steps that the Home-IOT interchanger receives a switching command sent by a control terminal; the Home-IOT interchanger selects DiiVA daisy chain modules corresponding to source device identification from multiple source devices according to the source device identification; the Home-IOT interchanger selects Home-IOT switching boxes corresponding to display device identification from multiple display devices according to the display device identification; the Home-IOT interchanger builds data channels between the selected DiiVA daisy chain modules and the selected Home-IOT switching boxes; the source devices input audio-video data into the display devices based on the data channels built by the Home-IOT interchanger. By means of the switching method and the interchanger, a non-compressed audio-video data flow can be transmitted based on the Home-IOT, and switching at will from the multi-way input to the multi-way output can be achieved.
