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; 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: assignment means 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, also called room, the collective site including one or more sites that share the same media information, wherein the reserved bandwidth is indicated in a media room generation request sent by an application server; and transmitting means configured to transmit, in response to a connection request to participate in the said media room (S111, S121) 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 transmitting means 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, characterized in that the connection response includes destination information specifying the media distribution server that distributes the media information as a destination, and wherein the distributable media distribution server further includes receiving means configured to receive the destination information transmitted from the communication apparatus at said another site. one or more media distribution servers configured to distribute media information to one or more communication apparatuses at one or more 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: assignment means 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, also called room, the collective site including one or more sites that share the same media information, wherein the reserved bandwidth is indicated in a media room generation request sent by an application server; and transmitting means configured to transmit, in response to a connection request to participate in the said media room (S111, S121) 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, assignment means 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, also called room, the collective site including one or more sites that share the same media information, wherein the reserved bandwidth is indicated in a media room generation request sent by an application server; and transmitting means configured to transmit, in response to a connection request to participate in the said media room (S111, S121) 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 transmitting means 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, characterized in that the connection response includes destination information specifying the media distribution server that distributes the media information as a destination, and wherein the distributable media distribution server further includes receiving means configured to receive the destination information transmitted from the communication apparatus at said another site.
