A head end (201) of a CATV center (200) and a transmission channel (300) form a LAN. A host device (202) for content distribution and a host device (101) of a subscriber (100) are connected to the transmission channel (300). A plurality of streams of content information are broadcast from the host device (202) over an upstream channel (301). The host device (101) of the subscriber (100) receives the streams sent through a downstream channel (302). Each stream is associated with a socket corresponding to a particular destination port number, and the host device (101) specifies a socket to receive, record or discard the streams in real time. |
