摘要:
An information processing terminal includes: circuitry to receive from a management system via a network, a candidate identifier of each one of one or more candidate counterpart information processing terminals that are previously registered for the information processing terminal; and to determine, in response to acceptance of an identifier that has been input, whether the accepted identifier matches any one of the candidate identifiers being received. Based on a determination indicating that the accepted identifier matches any one of the candidate identifiers, the circuitry transmits to the management system first request information requesting to start communication with the candidate counterpart information processing terminal identified with the accepted identifier. Based on a determination indicating that the accepted identifier does not match any one of the candidate identifiers, transmit to the management system second request information requesting to start communication with a counterpart information processing terminal identified with the accepted identifier, the circuitry transmits the second request information including destination information that differs from destination information included in the first request information.
摘要:
An information processing terminal: stores a counterpart list of one or more counterpart identifiers each representing a communication counterpart candidate of the information processing terminal; accepts a request destination identifier representing a counterpart information processing terminal, and participation authentication information; determines whether the request destination identifier matches any one of the counterpart identifiers; generates one of first communication start request information and second start request information, each request including the request destination identifier, the participation authentication information, and a request for communicating with the counterpart information processing terminal; and transmits the communication start request information to the communication management apparatus. When the request destination identifier matches the counterpart identifier, the circuitry generates the first start request information addressed to the communication management apparatus. When the request destination identifier does not match the counterpart identifier, the circuitry generates the second start request information addressed to the counterpart information processing terminal.

A control system includes a receiver configured to receive information relating to starting or ending a call between a first communications terminal and a second communications terminal while a session, which is for sending content data between the first communications terminal and the second communications terminal, is established; and a transmitter configured to send, to the first communications terminal, control information for starting output of content based on content data sent from the second communications terminal, in response to receiving the information relating to starting the call by the receiver, and to send, to the first communications terminal, the control information for stopping output of the content based on the content data sent from the second communications terminal, in response to receiving the information relating to ending the call by the receiver.
摘要:
An information processing apparatus includes: a transmitter to transmit content data to one or more counterpart information processing apparatuses through a network to have a communication with the one or more counterpart information processing apparatuses, the content data being at least one of image data and audio data; a receiver to receive, from a first information processing apparatus of the one or more counterpart information processing apparatuses, a recording start notification indicating that the first counterpart information processing apparatus starts recording or is recording the content data that is transmitted from the information processing apparatus, the recording start notification being transmitted with first identification information of the first counterpart information processing apparatus that is recording; and circuitry to output, based on the recording start notification, notification information indicating that recording of the communication is being performed, in association with information regarding the first counterpart information processing apparatus.
摘要:
An information processing apparatus for communication with an information processing device via a network disclosed. The information processing apparatus includes a display controlling unit configured to perform display control on a first screen that displays image data transmitted from the information processing device or on a second screen that displays information about the information processing device; and a first instruction receiving unit configured to receive a switching instruction to switch the first screen to the second screen. The display controlling unit performs the display control in a case where the first instruction receiving unit receives the switching instruction, such that auxiliary information about communication with the information processing device, the auxiliary information being displayed on the first screen, is not displayed on the second screen.
摘要:
A transmission system for managing communication between a first terminal and a second terminal includes a reception unit configured to receive request information from the first terminal, the request information indicating a category of a request of a first user of the first terminal; and a transmission unit configured to transmit an output request to the second terminal. The second terminal outputs image data to be displayed on the first terminal according to the category of the request of the first user of the first terminal upon receiving the output request.
摘要:
A multicast data communication system is provided that has high security, and prevents problems such as an attack by a malicious user creating a great number of meaningless tables at nodes in the network. Clients regularly transmit request packets toward a server; a node receives the request packet, and subsequently receives a delivery-table-creation packet or a delivery packet from the server; if the node has no delivery table corresponding to the server, the node creates the delivery table, registers the addresses of the clients, and their request packet arrival times, and regularly transmits the request packet toward the server; when the node has received a delivery packet from the server, the node duplicates and delivers the delivery packet only to those clients whose request packet arrival times, registered in the delivery table, are within a fixed period from the arrival of the delivery packet.

An electronic whiteboard to display visual information including handwritten data superimposed with a display image, includes a unit to authenticate a user; a unit to obtain user identification information for identifying the user in case where authentication of the user has succeeded; a unit to store the visual information associated with the user identification information; a unit to read the visual information associated with the user identification information; a unit to display the visual information; a unit to set a mail address of the electronic whiteboard as a transmission source, and to transmit the visual information to a specified destination by an e-mail; a unit to store the mail address of the user associated with the user identification information; and a unit to replace the transmission source by using the specified mail address of the user if the authentication of the user has succeeded.
摘要:
A communication management system starts transmission of first image data captured at a first communication terminal to a second communication terminal through a communication session for display at the second communication terminal, and in response to receiving a communication start request for starting communication with the second communication terminal from the first communication terminal, starts transmission of second image data and second audio data respectively captured at the second communication terminal to the first communication terminal, and first audio data captured at the first communication terminal to the second communication terminal, through the communication session, to enable communication between the first communication terminal and the second communication terminal.
