    • A data center includes a housing room (2) that nouses an information technology device (10a); an air conditioning machine (11) that cools air in the housing room (2) and supplies the air under a floor of the housing room (2); a grille (7) that allows the air supplied under the floor to circulate in the housing room (2); and a rack device (10) that houses the information technology device (10a). In the housing room (2) in the data center, the rack device (10) is arranged in such a way as to surround the grille (7). The information technology device (10a) is housed in the rack device (10) in such a way as to take in air from a space (20) surrounded by the rack device (10) via the grille (7) and discharge air to the housing room (2). The air conditioning machine (11) is arranged at a side from which the information technology device (10a) discharges air.

    • A digital information signal transmitting/receiving method and system having a transmitter (100) for transmitting an encrypted digital information signal and a plurality of receivers (200) for receiving the encrypted digital information signal from the transmitter (100). The transmitter (100) simultaneously distributes a plurality of identification codes associated with the receivers (200) ahead of the digital information signal. Then, the digital information signal is distributed to the receivers. The receivers (200) detect particular, or their own, identification codes from the plurality of identification signals assigned to the receivers (200). The received encrypted digital information signal is decrypted into the original information on the basis of the particular identification codes associated with the corresponding receivers or the recorders (300). Either the receivers (200) or the recorders (300) generate an information request signal. The transmitter (100) is responsive to this information request signal to add to the digital information signal identification signals for identifying the receivers (200) or the recorders (300) which generated the information request signal. The recorders (300) control the received information signal to be recorded in response to the identification signals received by the receivers (200).
