A transmission terminal transmits video data and display data of a screen shared with another transmission terminal to the other transmission terminal via a predetermined relay apparatus. The transmission terminal includes a storage unit that stores relay apparatus information of the relay apparatus to which the transmission terminal transmits the video data; a receive unit that receives the display data from an external input apparatus connected to the transmission terminal; and a transmitting unit that transmits the display data received by the receive unit to the relay apparatus indicated by the relay apparatus information stored in the storage unit.

Transmission terminal, transmission method, and computer-readable recording medium storing transmission program

A communication terminal receives display data for displaying certain data on a screen of a display device and image data of an optical-to-electrical-converted image from another communication terminal via a communication network, includes a storage part storing reception information indicating whether the display data has been received by the communication terminal and arrangement information indicating at least one of a size and a position of the image based on the image data, in a manner of associating with one another; a reception part receiving the display data and the image data; an extraction part extracting, based on the reception information, the corresponding arrangement information from the storage part; and a display control part displaying the image using the image data based on the arrangement information extracted by the extraction part.

Communication terminal, communication method and computer readable information recording medium

A communication device includes a first receiving unit configured to receive first metainformation indicating a target update required for a program of the communication device from an update information providing device, the first metainformation including information about a dependency version that is another version of update dependent upon the target update; a determining unit configured to determine whether the dependency version is newer than a device version which is a current version of update of the communication device; a second receiving unit configured to receive second metainformation indicating an update for the dependency version from the update information providing device if the dependency version is newer than the device version; and an update process unit configured to execute the update for the dependency version on the basis of the second metainformation and execute the target update based on the first metainformation after executing the update for the dependency version.

Communication device, update method, and computer-readable storage medium

An authentication system receives encrypted terminal identification information and terminal identification information, from a transmission terminal, and determines whether decrypted identification information decrypted using a terminal public key obtained by the authentication system matches the terminal identification information received from the transmission terminal.

Authentication system for terminal identification information

In a communication system, a communication terminal displays an image based on display data being displayed and sent by an external apparatus. The communication terminal sends first resolution data specifying a resolution of a display of the communication terminal to the external apparatus. The external apparatus determines a resolution of the display data to be transmitted, based on the first resolution data, and second resolution data specifying a resolution of a display of the external input apparatus. The external apparatus sends the display data, which is converted to have the determined resolution, to the communication terminal.

Apparatus, system, and method of communication, and recording medium storing communication control program

An apparatus, method, and system of assisting a user in the process of developing software having a function to access a web service are disclosed. A determination result is generated, which indicates whether an operation test of determining whether the software under development properly operates should be performed by a first test module or a second test module. Based on the determination result, the operation test is performed by a selected one of the first test module and the second test module.
