A host device (205) connected with a LAN (204) of an exchange office (200) transmits a plurality of streams of broadcast information. A subscriber (100) has a host device (101) belonging to the same network as the LAN (204) to receive the streams sent through a subscriber line (300). Each stream is assigned for a socket with an address port number, and the host device (101) sets a socket for real time reception, recording or discarding of the streams.
