Claim 12:
13. A distribution control apparatus for controlling distribution of media information between one or more communication apparatuses at one or more sites and one or more media distribution servers that distribute the media information to the communication apparatuses at the sites, the distribution control apparatus comprising circuitry configured to:
assign one of the one or more media distribution servers that is selected based on a reserved bandwidth of the media distribution server for distributing the media information and a maximum reserved bandwidth available to the media distribution server, as a media distribution server that distributes the media information to one or more communication apparatuses at a collective site, the collective site including one or more sites that share the same media information, each of the one or more media distribution servers including one or more rooms, each of the rooms connected to one or more of the sites, the media information being shared between the sites; and
transmit, in response to a connection request to connect to the assigned distribution media distribution server, transmitted from a particular communication apparatus of the one or more communication apparatuses at a particular site of the collective site, a connection response to the particular communication apparatus at the particular site,
wherein at each of the sites, when a room reserved bandwidth of the room is allocated, the media distribution server controls an uplink bandwidth for said each site and a downlink bandwidth for said each site, used for media information of said each site, such that the expression

BR>=Σuplink bandwidths(i)+Σdownlink bandwidths(i,j), is satisfied, where BR is a room reserved bandwidth, i corresponds to sites to which there are uploads, and j corresponds to sites where there are downloads.
