ABSTRACT:
The present invention relates to a broadcast service system where a broadcast transmission terminal is connected to a broadcast reception terminal through a plurality (large number) of switching nodes. The object of the invention is to provide a broadcast service system which has a small number of connection paths between switching nodes and can receive selectively, freely and arbitrarily broadcast program from the broadcast reception terminal. In the broadcast service system where a broadcast transmission terminal is connected to a broadcast reception terminal via a network having plural or many switching nodes, distribution modules, which control distributively input information, are formed so as to arrange to each or some of the switching nodes as an external circuit to an exchange switch in corresponding switching nodes.
