Abstract: A disclosed information processing apparatus is provided with a camera function and has installed a general-purpose application and a special-purpose application. The information processing apparatus includes a reader configured to read a code structure imaged by the camera function to convert the code structure into a string having a first part and a second part, and a translator configured to translate the string. When the code structure is read by the general-purpose application, the first part of the string is translated as a URI via the general-purpose application to activate basic software function, and when the code structure is read by the special-purpose application, the second part of the string is translated via the special-purpose application to activate a function of the special-purpose application.

Abstract: A communication management system manages group information regarding one or more groups of a plurality of communication terminals, while the plurality of communication terminals are communicating in the same communication session. In response to a request from one communication terminal, the communication management system updates the group information to reflect the currently-established groups, and transmits updated group information to all of the plurality of communication terminals communicating in the same communication session.

Abstract: The communication terminal determines whether a delay in output of an output signal based on first content data is detected, the first content data being received from a first counterpart communication terminal through a network, generates a first request for changing a code quantity of the first content data being received based on a determination indicating that the delay is detected, the first request including a reduction coefficient for determining an amount of reduction in the code quantity of the first content data being received, and transmits the first request to the first counterpart communication terminal that transmits the first content data, through the network.

Abstract: In a communication system, a plurality of communication terminals including first communication terminals and second communication terminals are connected through a network. The communication system includes: a communicator that transmits and receives content data; an executor that controls, when first communication is established between communication terminals, the communicator to transmit and receive content data to and from a first communication terminal and not to transmit content data to a second communication terminal but to receive content data from the second communication terminal, in a predetermined transmission band; and a receiver that receives selection of a second communication terminal with which second communication is to be established.

Abstract: A control system is provided. The control system includes a state management unit configured to control state information indicating a state of a communication terminal and a control unit configured to, when a first communication terminal and a second communication terminal communicate, determine whether content data should be transmitted from the first communication terminal to the second communication terminal and whether content data should be transmitted from the second communication terminal to the first communication terminal based on a set of the state information indicating the state of the first communication terminal and the state information indicating the state of the second communication terminal controlled by the state management unit.

Abstract: A communication terminal receives first state information that indicates transition of a state of a counterpart communication terminal from a previous state to a current state, determines whether the communication terminal currently has a state associated with the current state of the counterpart communication terminal indicated by the first state information, and control output of content data transmitted from the counterpart communication terminal for display at the communication terminal based on determination. When the determination indicates that the communication terminal has the state associated with the current state of the counterpart communication terminal, the content data transmitted from the counterpart communication terminal is output for display at the communication terminal.

Abstract: A communication terminal receives first state information that indicates transition of a state of a counterpart communication terminal from a previous state to a current state, determines whether the communication terminal currently has a state associated with the current state of the counterpart communication terminal indicated by the first state information, and control output of content data transmitted from the counterpart communication terminal for display at the communication terminal based on determination. When the determination indicates that the communication terminal has the state associated with the current state of the counterpart communication terminal, the content data transmitted from the counterpart communication terminal is output for display at the communication terminal.

Abstract: There is provided a transmission system transmitting at least one of image data and audio data among a plurality of transmission terminals. A first transmission terminal includes a state detector that detects whether a user is present therearound, and a controller that controls to transmit correspondence data corresponding to a result detected by the state detector to a second transmission terminal when a state detected by the state detector changes. The second transmission terminal changes quality of at least one of the image data and the audio data that is transmitted to the first transmission terminal in accordance with the correspondence data and transmits at least one of the image data and the audio data when the second transmission terminal receives the correspondence data.

Abstract: A communication terminal is controlled such that the communication terminal does not transmit content data from the communication terminal to one or more communication terminals through a first session, but transmits content data from the communication terminal to a selected communication terminal of the one or more communication terminals through a second session after the second session is established with the selected communication terminal.

Abstract: A system stores, in a memory, first service identification information for identifying a service to be used by a first communication terminal that requests for content data, second service identification information for identifying a service to be used by a second communication terminal that transmits content data, and content data information indicating property of content data that can be transmitted to the first communication terminal, in association with one another. After a session for transmitting content data is established between the first communication terminal and the second communication terminal, the system controls transmission of content data from the second communication terminal to the first communication terminal, so as to transmit content data having a property indicated by the content data information that is stored in association with the first service identification information and the second service identification information.
