Abstract: An electronic information content automatic distribution service system according to the present invention is directed to a service system for automatically distributing electronic information contents based on a utilization contract made in advance between an information provider and a user. This system comprises: information distributing means for distributing electronic information contents to the user; and an information processing apparatus for receiving and processing electronic information contents distributed from this information distributing means. The information processing apparatus calls and connect the information distributing means at a preset first time. In addition, the apparatus receives and stores the electronic information contents from the information distributing means. Then, the apparatus reads out and displays the electronic information contents at a second time.

Abstract: In executing a setup procedure of a call from a VoIP gateway on the originating side to a media gateway on the destination side via a gate keeper, an authentication key is transmitted from the gate keeper to the VoIP gateway and the media gateway. The VoIP gateway on the originating side transmits to the media gateway on the destination side an admissions confirm (ACF) after attaching the authentication key. Then, the media gateway collates the authentication key obtained from the originator VoIP gateway with the authentication key obtained from the gate keeper and continues the call setup procedure only when the two authentication keys coincide with each other. On the other hand, in case of non-coincidence, the gate keeper carries out a call release. Through this, an illegal connection call not routing through the gate keeper is excluded without fail.

Abstract: A system and method for automatically configuring network settings on a computer terminal via a network interface card so that the computer terminal can communicate on a local area network, without requiring users to manually input the network settings. A network interface card is inserted into a computer terminal device. The network interface card automatically determines whether the computer terminal should be configured as host server or a client based on whether another host server is detected on the network. Based on this determination, the network interface card communicates with the host server and receives network configuration information and automatically sets the network settings for the computer terminal. A further embodiment of the invention includes pre-loading a presentation data application program on the network interface card, such that each terminal in the network can display a received presentation or transmit a presentation to the other terminals.

On one hand, utilization condition information concerning lease of information contents are added to the information contents by means of the information lease management apparatus (1), and then, is processed so as to be distributed to a user. On the other hand, information contents with utilization condition information distributed from the information lease management apparatus (1) are received, and are rented by means of the information processing apparatus (3).

Abstract: In an apparatus for producing duplicate tapes by transmitting signals reproduced by a master VTR to a plurality of duplicating VTRs for simultaneous recording on respective tapes in the latter; control signals from a bidirectional remote control unit are modulated with a first modulating frequency and are transmitted over a bidirectional control signal line to the duplicating VTRs. If a response is required from one of the duplicating VTRs, response signals from such duplicating VTR are modulated with a second modulating frequency different from the first modulating frequency and, during a pause in signal transmission from the remote control unit, the modulated response signals are transmitted to the remote control unit over the bidirectional control signal line.
