To provide a communication control device and a communication control method which enable an existing client terminal which can not execute a band control process, to receive a QoS-guaranteed streaming type content distribution service.

The communication control device 105 is installed between a home network and a QoS controllable external network in a streaming type content distribution service using a real time streaming protocol (RTSP), and the communication control device 105 includes: a message acquiring section 402 for acquiring an RTSP message exchanged between an RTSP client device and an RTSP server device; a QoS control information generating section 403 for acquiring information required for QoS control from the RTSP message acquired by the message acquiring section 402; and a QoS control section 404 for establishing a QoS session for video transmission with the RTSP server device on the basis of the information, required for QoS control, acquired by the QoS control information generating section 403.
