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 method implemented by a communication system, including at least a first electronic device and a second electronic device, includes that the first electronic device plays multimedia content. The first electronic device sends first synchronization information through broadcast, so that the second electronic device receives the first synchronization information, where the first synchronization information includes at least a first address, and the first address is an obtaining address of the multimedia content. In response to a preset operation, the first electronic device establishes a near field wireless communication connection to the second electronic device, and the second electronic device caches the multimedia content based on at least the first address. The first electronic device sends a control instruction to the second electronic device by using the near field wireless communication connection. The second electronic device plays the multimedia content based on the control instruction.
