In response to a resource acquisition request received from a terminal device, whether or not there is an available communication resource among a plurality of communication resources used for receiving or transmitting broadcast signals is checked. When those communication resources are being used and there is not an available communication resource, that resource acquisition request is held temporarily, and release of a communication resource being used is waited for. When a communication resource that has ceased to be used is released, the released communication resource is allocated to the resource acquisition request that has been held.
