A communication control system or a communication control apparatus executes communication control among A/V (audio/visual) equipment or due to mutual connection with various information equipment. The communication control apparatus has a communication identification information memory section to store predetermined identification names and a processing procedure unit for inquiring and confirming that communication can be mutually executed by using the identification names. In the above construction, in the case of expanding a command by using a command for command expansion and information indicative of the kind of expansion, the transmission side transmits the identification name to the reception side by using a predetermined inquiry confirmation processing procedure and is collated with the identification name stored, thereby sending to the transmission side the information indicative of the result of the discrimination with respect to whether the mutual communication by the command expansion can be executed or not.
