A multimedia broadcasting system having a multiple-node structure includes nodes. Each node is coupled to at least one of the nodes, and the nodes include server nodes and multimedia-playing terminal nodes. Each server node is coupled to at least one of the server nodes and provides at least one multimedia content. Each multimedia-playing terminal node receives multimedia content transmitted by a server node of the server nodes and plays the multimedia content. A first server node of the server nodes is coupled to a second server node of the server nodes, and the first server node transmits, via the second server node, a first multimedia content to at least one multimedia-playing terminal node controlled by the second server node. Each multimedia-playing terminal node is a multimedia play terminal including at least one display device or audio playing device.
