1. A time code synchronization method applied to a network system, wherein the network system comprises a plurality of nodes, and the method includes:
determining a target master node and one or more target slave nodes of the network system among the plurality of nodes;
upon determining the target master node and the one or more target slave nodes of the network system, periodically sending a data packet to the one or more target slave nodes by the target master node, wherein the data packet comprises a first time code and a serial number information of the target master node; and
compensating the first time code by the one or more target slave nodes according to the serial number information to obtain a second time code, and synchronizing the second time code by the one or more target slave nodes;
wherein the first time code in the data packet sent by the target master node is the same, and the serial number information is different.
