Abstract: A data transmission method and an electronic device are provided. One uplink interface and one downlink interface are deployed on each input device of the electronic device. The uplink interface is connected to a processor or an upper-level input device, and the downlink interface is connected to a lower-level input device. A processing module in each input device may process image data collected by the current-level device and data sent by a lower-level input device connected to a downlink interface, and then transmit processed data to the processor or an upper-level input device through an uplink interface. Thus the plurality of input devices are connected in a cascade manner, and only one of the plurality of input devices needs to be connected to the processor.

Abstract: A method includes: A first transmission unit packs, at a protocol layer of the first transmission unit, to-be-transmitted data of an application layer of the first transmission unit, to generate a data packet. The data packet includes data type information, the data type information indicates an application scenario of the data packet, and the application scenario includes any one of a camera scenario, a display scenario, and a storage scenario. The first transmission unit sends the data packet to a physical layer of the first transmission unit through the protocol layer of the first transmission unit. The first transmission unit sends the data packet to a second transmission unit through the physical layer of the first transmission unit.
