Specifically, multiple display terminals are connected to a unified local area network, and data transmission is performed according to a predefined network protocol. The first program synchronization message refers to a message sent to determine whether the display terminal in the display terminal cluster can normally receive the program. The identifier of the program to be synchronized refers to the identifier of the program to be synchronized. Specifically, the program to be synchronized may be a piece of video, an image, etc., which is not specifically limited here. In this embodiment, optionally, the program data may be stored in one of the display terminals of the display terminal cluster in advance, as the first current display terminal to synchronize the program to other display terminals, or it may be through the control terminal Synchronize program data to one of the displays.

In an optional implementation manner, if there is one current display terminal, before the broadcast of the first program synchronization message to the display terminal cluster, it may include that the current display terminal receives the program data sent by the control terminal. Specifically, the control terminal and the display terminal cluster are under the same local area network. It can be understood that, when the control terminal selects a display terminal to send program data, reference may be made to the solution of the current display terminal sending program data in any embodiment, and no specific limitation is made here.

In an optional implementation manner, the display terminal that synchronizes the program data and/or receives the program data is in an occupied state during the transmission of the program data, and in the occupied state, the display terminal is in the program data The program data sent by the other display terminals is no longer accepted before the transmission is completed, and the method for synchronizing the program further includes:

Specifically, if the status is normal, it means that data can be received normally, and if the status is abnormal, data cannot be received normally.

S130. The current display terminal uses one of the multiple display terminals as the target display terminal based on the status message, and synchronizes the program data corresponding to the identifier of the program to be synchronized with the target display terminal, so that the target display terminal Play the program to be synchronized, wherein the target display terminal is different from the current display terminal;

The target display terminal refers to a display terminal that is about to receive program data sent by the current display terminal and is different from the current display terminal among the multiple display terminals. Specifically, if the current display terminal sends the program data to the target display terminal, the target display terminal can play the program to be synchronized normally after receiving the program data.

Optionally, the current display terminal continues to play the program to be synchronized while sending the program data to the target display terminal.

S140. Define the target display terminal as the current display terminal, and re-execute the step of broadcasting the first program synchronization message to the display terminal cluster, until each display terminal in the display terminal cluster plays the to-be-synchronized program.

The synchronization permission message maps the candidate display terminal to compare the identifier of the program to be synchronized with the identifier of the pre-synchronized program and does not receive the program identifier to be synchronized. Synchronizing the result of the program data corresponding to the program identifier; taking one of the target candidate display ends as the target display end.

Wherein, the second program synchronization message refers to a message sent to determine a target candidate display terminal among the candidate display terminals. The pre-synchronized program identifier refers to the identifier of the program to be synchronized to the target display terminal. Specifically, when the candidate display terminal receives the second program synchronization message, it will respond to the second program synchronization message to obtain a corresponding message and return to the current display terminal. The current display terminal can determine the target candidate display terminal among the candidate display terminals according to the response message. . Specifically, the candidate display terminal corresponding to the response message allowing the synchronization message is used as the target candidate display terminal. It should be noted that the candidate display terminal is allowed to map the synchronization message to the result that the identifier of the program to be synchronized is consistent with the identifier of the pre-synchronized program and the program data corresponding to the identifier of the program to be synchronized is not received. Specifically, when the candidate display terminal receives the second program synchronization message, it extracts the pre-synchronized program identifier from the second program synchronization message, and compares the pre-synchronized program identifier with the program identifier to be synchronized included in the first program synchronization message. If they are consistent, then determine whether the program data corresponding to the program identifier to be synchronized has been received, if not, generate a synchronization permit message and return it to the current display, and the current display determines the target candidate display end according to the synchronization permit message, and the target One of the candidate display terminals serves as the target display terminal to send program data.

In this embodiment, optionally, when the received response messages of all candidate display terminals are synchronization rejection messages, it may be considered that the program synchronization is completed.
