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.

Abstract: A method includes: a processor that obtains several lines of data in to-be-displayed display data to generate a data block; generates a synchronization flag corresponding to the data block; encapsulates the data block and the synchronization flag corresponding to the data block to obtain a data packet corresponding to the data block; and sends all data packets corresponding to the display data to the display system. The display system sequentially parses all the data packets sent by the processor to obtain a synchronization flag associated with each data packet, and determines a display location of each data block on a display panel based on the synchronization flag to display the display data.

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.
