A unit for realizing a TV phone by using an image and a character message by a relatively simple method in a manner mode is provided. In the manner mode of one mobile TV phone terminal, a control unit for controlling the operation of the one mobile TV phone terminal prohibits the sound input via a microphone of the one mobile TV phone terminal and the sound output via a speaker and operates an SMS function with a TV phone function. A line between the one mobile TV phone terminal and another one is connected, an SMS message is created by operating a key input unit of the one mobile TV phone terminal, and a send key is pressed. Then, the message data is sent to the other mobile TV phone terminal via one base station, an SMS server, and another base station. A display unit of the other mobile TV phone terminal displays the message together with the image sent via a TV phone exchange.

In a cellular phone which receives a television signal by means of a TV receiving section (200), when the cellular phone is brought to an open state after detecting an incoming call while receiving a television signal with the cellular phone kept in the closed state, the television receiving operation ceases automatically for communication by telephone, and thereby the user is not required to execute a troublesome operation to quit receiving the television signal. The control section (22) in the cellular phone does not cease receiving the television signal while the user is talking on the phone and outputs telephone talking voice in place of the television sound. Therefore, the user can enjoy watching the television image while talking on the phone. Further, since the cellular phone displays on a display section (13, 16) the television image and caller's information simultaneously, the user can confirm the caller's information.

A television phone adapter which permits an ordinary analog telephone to switch between being a telephone with a video function and a telephone without a video function. The television phone adapter includes a telephone adapter unit that detects dial operation of an analog telephone connected to a router with an IP telephone function, a video adapter unit that connects and disconnects a video connection using an IP network, sends a video taken by a camera to a communication partner and outputs a video received from the communication partner to a display 4 through the video connection in the connected state. A translation table stores correspondence between dial operation and a setting content. A main control unit controls connection and disconnection of the video connection by the video adapter unit, according to setting / content items corresponding to dial numbers or dial tones detected by the telephone adapter unit, when the control content translation table stores the setting / content items corresponding to the dial numbers or tones detected by the telephone adapter unit.

A teleconferencing environment is provided in which both audio and visual cues are used to identify active participants and presenters. Embodiments provide an artificial environment, configurable by each participant in a teleconference, that directs the attention of a user to an identifier of an active participant or presenter. This direction is provided, in part, by stereo-enhanced audio that is associated with a position of a visual identifier of an active participant or presenter that has been placed on a window of a computer screen. The direction is also provided, in part, by promotion and demotion of attendees between attendee, active participant, and current presenter and automatic placement of an image related to an attendee on the screen in response to such promotion and demotion.

A method determines a route in distance value for use in routing protocols. An optimum route is determined for time-critical transmissions such as videotelephony or VoIP. For this purpose, the route distance value is calculated as the product of the link metrics for the links of a route, said link metrics being the product of data packet arrival rates. This value is the optimum value for the route which requires the lowest number of repeated packet transmissions (retransmissions). Optionally, an additional factor can be inserted in the link metrics, which factor ensures that the length of a route is also taken into consideration.

A display apparatus and method are provided. The display apparatus includes a videotelephony performer that is configured to perform a videotelephony with another display apparatus; and a controller configured to control a corresponding feedback that is output when gestures and speech of a user and the other party of the videotelephony have a preset correlation during a process in which the videotelephony is performed.

It is possible to provide an at-home medical examination service having an environment in which a patient can feel as if the patient were actually in a hospital. That is, it is possible to cope with a sudden change of the patient or the like even if a patient terminal is not connected to a doctor terminal and the patient's sense of anxiety and loneliness for the sickness can be eliminated without increasing the load on the doctor. An at-home medical examination system includes a reception server , a communication server , a mail server, an administration management server, doctor terminals , a nurse terminal , a waiting room terminal , a reception terminal , and a pharmacy terminal. The at-home medical examination system is connected via a communication line to patient terminals and provides the at-home medical examination service via a video telephone. The communication server has a connection destination table and provides a virtual examination room, a virtual waiting room, a virtual nurse care room, a virtual individual conversation room, and the like according to the purpose. The patient terminal has a nurse call button and a medical examination sensor so that a nurse terminal is called upon a sudden change of the patient state and the patient vital can be monitored.That is, it is possible to cope with a sudden change of the patient or the like even if a patient terminal is not connected to a doctor terminal and the patient's sense of anxiety and loneliness for the sickness can be eliminated without increasing the load on the doctor.

A videotelephony image modulation apparatus and method detects an event having a possibility of information leakage by analyzing an image and provides a secured calling mode of masking all or a part of the image and transmitting a masked image obtained through the masking.

The invention relates to the field of communication and discloses a method and a system for calling a video phone so as to realize a multi-media polyphonic ringtone service of a video phone with less cost. The method comprises the following steps: a multi-media ring-back tone server plays multi-media ring-back tone to a calling terminal by a first load of the video phone f established with the calling terminal; after a called terminal is detected to be off-hook, a second load of the video phone is established between the called terminal and the multi-media ring-back tone server, and the videophone communication is carried out between the calling terminal and the called terminal by the established first load and the second load, or the multi-media ring-back tone server plays the multi-media ring-back tone to the calling terminal by a third bearing of the video phone established with the calling terminal; a fourth load of the video phone is established between the calling terminal and the called terminal, and the video phone communication is carried out between the calling terminal and the called terminal by the fourth load.

A communication terminal which is divided into an enclosure for video / audio communication and another enclosure for audio communication only. The functions of the enclosure for audio communication only are limited, and the size of the enclosure can be so small that it can be carried in a pocket. Therefore, when an incoming call arrives, off-hook of the enclosure can be done immediately. When visual telephone is requested, off-hook is done using the enclosure for only audio communication, and audio communication with the party terminal can be immediately made. When necessary, audio / video communication can be made using the enclosure for audio / video communication by changing the enclosure.
