Synchronous screen content transmission method and synchronous screen content transmission device through wireless transmission

The invention relates to the field of wireless transmission, and in particular relates to a synchronous screen content transmission method and a synchronous screen content transmission device through wireless transmission, applicable to Bluetooth signal transmission between first equipment and second equipment. The synchronous screen content transmission method comprises the following specific steps: S1, opening Bluetooth functions of the first equipment and the second equipment; S2, searching the first equipment through the Bluetooth functions and connecting the first equipment to the second equipment, and quitting if connection is unsuccessful; S3, transmitting a Bluetooth signal of a current playing content to the first equipment by the second equipment; and S4, playing a content same in the equipment by the first equipment. The synchronous screen content transmission method and the synchronous screen content transmission device disclosed by the invention have the benefits that: same screen contents are played in a mobile terminal and a television in wireless connection; therefore, large screen requirements of users are satisfied; simultaneously, the length limited problem of a data line is solved; use is more convenient; furthermore, network resources of the mobile terminal can also be shared in the event that the television is not accessed to a network; and thus, the application range is wide.
