A communication apparatus includes: a display state detecting unit that detects a display state of an image to be displayed on the basis of a received moving image data; and a control information transmitting unit that transmits, to a transmission source of the moving image data, control information regarding transmission of the image data, in accordance with the display state.

Communication apparatus

A teleconferencing device includes: a connecting unit fitted into an information processing device; and a storage unit storing: a teleconference application program which is automatically started by fitting the connecting unit into the information processing device; self-location information which is location information of the teleconferencing device; and destination location information which is location information of a connection destination holding a teleconference, wherein the teleconference application program reads the self-location information and the destination location information and connects the information processing device to an information processing device of the connection destination via a network.

Teleconferencing device, and teleconference initiating method and program thereof

A version update method is provided for updating a version of a communication system application program installed in a plurality of terminals connected to a communication network and operating between at least two terminals. The method includes: starting communications between the two of the plurality of terminals; exchanging version information of the communication system application program between the two terminals communicating with each other and making a comparison between the version information held in one terminal and that in the other; making a request for transmitting the communication system application program file of the version not held in either terminal; and transmitting the communication system application program file of the specified version to the terminal making the request.

Method of updating a version of an application program

A voice conference apparatus includes: a communication unit that transmits and receives a first voice signal to and from another apparatus via a network; an output unit that reproduces the first voice signal received by the communication unit and outputs the reproduced first voice signal as a first voice; an input unit that collects the first voice and a second voice generated by a voice source, as a second voice signal; a separating unit that separates the second voice signal into a third voice signal originated from the first voice and a fourth voice signal originated from the second voice; and a selecting unit that selects one of the third voice signal and the fourth voice signal. The communication unit transmits the one of the third voice signal and the fourth voice signal selected by the selecting unit to the other apparatus.

Voice conference apparatus, method for confirming voice in voice conference system and program product

Participant terminals which are to be connected to a promoter terminal are configured by speaker terminals which are enabled to perform two-way communication with the promoter terminal, and audience terminals which are enabled to perform one-way communication with the promoter terminal. The connection line number M of participant terminals which are connected to the promoter terminal is set to M=2S+T where S is the number of connected speaker terminals and T is the number of connected audience terminals. As a result, the total amount of communication is suppressed to S&#xd7;(K&#x2212;1) (K=S+T) as compared with the conventional art in which all participant terminals are configured by speaker terminals.
