Provided are a method and a system for providing a virtual messenger service between a mobile communication terminal and a computer. The method includes executing a virtual messenger program for controlling a function of a mobile communication terminal, and receiving a telephone directory provided within the mobile communication terminal; displaying a messenger window when receiving a request for activating the messenger window that collectively includes the telephone directory and menus; generating a communication event message related with a selected telephone number of the other party; and transmitting the generated event message to the mobile communication terminal, and displaying a notification of a communication event to an other party.

Either of a first person image capturing a person located in front of a first projection surface from a first projection surface side and a second person image capturing the person from an opposite side of the first projection surface with respect to the person is projected on a second projection surface of a remote place.

A videoconference device displays video data from a speech site such that a viewer can easily understand even in a case where the number of sites is large. A communication controller receives each piece of video data and voice data from conference terminal devices of a plurality of other sites. A video and voice synthesizer determines a screen layout depending on the number of sites participating in a videoconference, and generates synthesized video data obtained by synthesizing video data of each site according to the screen layout. At this time, the video and voice synthesizer generates the synthesized video data such that display of the video data of each site where a level of voice data is higher than or equal to a threshold is highlighted more than display of video data of the other sites. A video and voice output controller displays the synthesized video data on a screen of a display device.

Implementations generally relate to virtual reality telepresence. In some implementations, a method includes positioning a first user in a virtual environment, and determining a first point of view associated with the first user. The method further includes positioning a second user in the virtual environment, and determining a second point of view associated with the second user. The method further includes projecting one or more of the first user and the second user in the virtual environment based on a first positioning of the first user and a second positioning of the second user and based on the first point of view and the second point of view.

Methods and systems are described for storing video content collected by a home automation system. According to at least one embodiment, an apparatus for accessing video content collected by a home automation system includes a processor, a memory in electronic communication with the processor, and instructions stored in the memory which are executable by a processor to receive at a remote device live video content from a camera of the home automation system, and initiate real-time, two-way audio communication between the remote device and a user of the home automation system via the camera.

The present invention discloses a method for implementing a video phone on a communication terminal, and the communication terminal thereof. The method comprises the steps of: determining, by the communication terminal, that it supports video phone services and is located in a second communication access network which supports the transmission of a second data contained in the video phone services; initiating or waiting for a video phone call; establishing and maintaining a video phone connection with a second communication terminal; and switching CS domain services to a first communication access network which supports the transmission of a first data contained in the CS domain services after the video phone connection is terminated. The second communication access network supports the transmission of the second data contained in the video phone services, so it is able to implement the video phone services in the second communication access network in accordance with a predetermined service process, and to implement the CS domain services via the first communication access network in an area not covered by the second communication access network.
