(4) The communication interface on the signal processing integrated circuit board is generally a USB interface, the keyboard or the mouse is also a USB interface, and the software encryption lock is also a USB interface, so that at least 3 USB interfaces are required to be used on the host, and for some novel multimedia devices (such as a Tianmao magic box, a smart phone, a tablet personal computer, a smart television and a head-mounted virtual implementation all-in-one machine), only 1 to 2 USB interfaces are usually used, and the USB interfaces cannot be directly used.
