Patent ID: 7990890

Claim:
A communication management apparatus that is connectable to an audio data communication management system, which includes a plurality of communication management apparatuses, wherein said communication management apparatus and other communication management apparatuses are connected to a network, said communication management apparatus comprising: a first transmitter that transmits an audio data at a first transmission rate to the network; a first memory that stores a first status data representing all setting status of the communication management apparatus; a second transmitter that transmits, to all of the other communication management apparatus connected to the network, the first status data at a second transmission rate lower than the first transmission rate; a first receiver that receives a second status data representing all setting status of the other communication management apparatuses at the second communication rate from the other communication management apparatuses via the network; a second memory that stores the second status data received from the other communication management apparatuses; a second receiver that receives, simultaneously with another one of the other communication apparatuses, an order data generated by one of the other communication management apparatuses that is set as a master apparatus via the network, wherein the order data represents a sequential order of transmission, by each of the respective one of plurality of the communication management apparatuses that are included in the audio data communication management system, of a first modification data for modifying the first status data, wherein said order data is transmitted once during each cycle of transmission; a third transmitter that transmits, at the second communication rate and at an order specified by the order data, the first modification data to all of the other communication management apparatuses connected to the network; a third receiver that receives a second modification data instructing modification of the second status data from at least one of the other communication management apparatuses; and a modifying device that modifies the second status data stored in the second memory based on the second modification data received.
