A communication system comprises a bridge device being configured to manage multi-channel communications, a host terminal coupled to the bridge device through a first network, a participant terminal coupled to the bridge device through a second network, and a broadcasting device coupled to at least one of the host terminal and the bridge device for broadcasting at least one of the participant signals from the participant terminal and the host signals from the host terminal. The host terminal is configured to receive host signals and to transmit the host signals to the bridge device. The participant terminal is configured to receive participant signals and to transmit the participant signals to the bridge device. The bridge device is configured to receive the participant signals from the participant terminal and the host signals from the host terminal and transmit the participant signals from the participant terminal and the host signals from the host terminal only to the host terminal but not another participant terminal.
