Claim 0:
1. A media distribution system comprising:
one or more media distribution servers configured to distribute media information to one or more communication apparatuses at one or more sites, 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
a distribution control apparatus configured to control distribution of the media information between the one or more media distribution servers and the one or more communication apparatuses,
the distribution control apparatus including first 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; and
transmit, in response to a connection request to connect to the assigned distributable 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,
the distributable media distribution server including second circuitry configured to
transmit, in response to the connection request from the distribution control apparatus, the media information transmitted from the particular communication apparatus at the particular site of the collective site, to another communication apparatus at another site different from the particular site of the collective 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.
