Abstract: In an effort to transmit/receive MDI data in a session among a plurality of terminals, when any of the terminals designates a communication partner and transmits a request to join a session to a management server 100, the management server allows the terminal to join a session joined by the designated communication partner, allocates a channel different from those allocated to the other terminals in the session, and notifies the allocated channel together with information on the terminals joining the session. Further, the terminal sets communication destinations based on the notification.

Abstract: A portable music player downloads a musical composition data from a distribution server. When this musical composition data is played back, a sample musical composition data composing a part of the musical composition data is distributed to a surrounding player by wireless. At this time, a terminal identification number IDa of the supplier player is included in tag information of the sample musical composition data, and the user of the surrounding player can download the musical composition data related to the sample musical composition data for value from the distribution server. A part of its sold price is refunded to the user of the supplier player.

Abstract: Operational states of one or more operators employed in a vehicle are detected to generate operational information corresponding to the detected operational states. Also, one or more traveling states of the vehicle are detected to generate traveling information corresponding to the detected traveling states. There is provided a table storing correspondency between various operational and traveling information and various sound control information, and sound control information corresponding to generated operational or traveling information is obtained with reference to the table. Sound signal is generated on the basis of the obtained sound control information to auditorily inform a user of the vehicle of the operational or traveling state of the vehicle. Contents of the table may be changed as desired by the user. There may be provided a plurality of tables so that the user can select any one of the tables.

Abstract: For performing a session in which performance data are mutually exchanged with other terminals via a communication network, a terminal searches for a master device managing the session, and when the master device is found, transmits a join notification to the master device to receive a notification of an allocated channel in response and also stores identification data notified from the master device. When the master device is not found, the terminal itself functions as the master device to allocate a channel in response to a join notification and to notify information on the terminals joining the session.

Abstract: Detection is made of an activated direction of a vehicular operator device capable of being activated in at least two directions. In response to activation, in a first direction, of the operator device, informing sound is generated which varies over time with a first characteristic, and, in response to activation, in a second direction, of the operator device, informing sound is generated which varies over time with a second characteristic generally opposite to the first characteristic. For example, when a right turn is instructed, informing sound is generated with a characteristic to progressively raise the sound pitch from a relatively low sound pitch, while when a left turn is instructed, informing sound is generated with a characteristic to progressively lower the sound pitch from a relatively low sound pitch (, or vice versa).
