ABSTRACT:
A video data providing unit (10) connects to a restricted access providing-side VPN (20). A streaming server (60) connects to a restricted access transmitting-side VPN (50). A router (40) determines whether or not transmitting-side data such as request data or instruction data received via the transmitting-side VPN (50) is data that has been transmitted from the streaming server (60), and whether or not providing-side data such as video data received via the providing-side VPN (20) is data that has been transmitted from the information providing unit (10). The router40then transfers the transmitting-side data and providing-side data based on those determination results.
