Abstract
Description
The present invention relates to a video call screen mode control system and method, and more particularly, to a video call screen mode control system and method for controlling a video call screen mode of a counterpart during a video call.
With the rapid development of mobile communication technology and infrastructure, mobile communication terminals provide various additional service functions such as Internet search, wireless data communication, electronic organizer, and video call function as well as general voice call.
Among these, the video call function is to perform a call while transmitting / receiving an image captured by a camera with a counterpart terminal. Allows the user to conduct a call while looking at you with the other party.
1 is a road showing an example of a video call screen generally used in a video call, the mobile communication terminal in the video call, the image received from the counterpart and the image taken by the camera and the main screen (a) and secondary It is displayed using the screen (b).
As described above, the image received from the counterpart and the image taken by the camera are displayed on the terminal screen during a video call. Conventionally, a screen mode selected by the terminal user at the time of environment setting (for example, the counterpart is enlarged, Organize your screen according to how big you are, only yours, only you, or full screen.
Meanwhile, as the video call service is activated and the service area is enlarged, a video call is provided to a video service server in which a mobile communication terminal provides specific video data (for example, real-time traffic situation video data) as well as a video call between the terminal and the terminal. Increasingly, video call service with a video service server is provided by attempting to connect.
As described above, when the video call service is provided by connecting the video service server to the video call, it is effective to display the counterpart image provided by the video service server on the entire screen.
However, conventionally, even when a video call service is provided by connecting a video service server and a video call, the screen is configured according to the screen mode selected by the terminal user at the time of environment setting.
Accordingly, in the related art, a case in which both of the counterpart image provided by the video service server and the own image are displayed on the small terminal screen or only the own image is displayed on the screen, and the counterpart image provided by the video service server is displayed. There is a problem that the terminal user needs to reset the screen mode in order to display it in full.
The present invention has been made to solve the above-mentioned problem, the video call screen mode of the terminal connected to the video call call to the video service server so that the video data provided by the video service server is displayed on the entire screen in the video service server It is an object of the present invention to provide a video call screen mode control system and method for controlling.
Another object of the present invention is to provide a video call screen mode control system and method for controlling a video call screen mode of a counterpart terminal in which a video call is set in one terminal.
According to an aspect of the present invention, there is provided a video call screen mode control system, including: a terminal supporting a video call function and a screen mode control function; A server that provides video data. When the terminal receives information that the terminal supports a screen mode control function from the terminal during negotiation with the terminal to generate a video and audio channel, the screen mode of the terminal is changed to a specific screen mode. It is preferable that the video service server for transmitting a screen mode control message set to a specific screen mode to the terminal to switch.
Further, when the terminal receives the screen mode control message from the video service server, it is preferable to switch the video call screen to a specific screen mode based on the screen mode set in the screen mode control message.
The terminal may provide information indicating that the terminal supports a screen mode control function to the video service server using a negotiation message.
On the other hand, the video call screen mode control method according to an embodiment of the present invention, after the video call call is connected between the terminal that supports the video call function and the screen mode control function and the video service server providing the video data, A first step of providing information indicating that the terminal supports a screen mode control function from the terminal to the video service server when negotiating a voice channel; Transmitting, by the video service server, a screen mode control message set to a specific screen mode to the terminal to change the screen mode of the terminal to a specific screen mode; And a third step of switching the video call screen to a specific screen mode based on the screen mode set in the screen mode control message in the terminal receiving the screen mode control message.
On the other hand, the video call screen mode control method according to another embodiment of the present invention, after the calling terminal sends a video call call to the called terminal and the call is connected between the calling terminal and the called terminal, for generating a video and audio channel A first step of providing information indicating that the screen mode control function is supported to the counterpart terminal when the negotiation is performed; After the negotiation for generating the video and audio channels is completed, the caller terminal and the called terminal may be selected from the calling terminal and the called terminal at the request of the terminal user who wants to control the screen mode of the other terminal while performing a video call using the video and audio channel. Transmitting, by a terminal, a screen mode control message set to a screen mode designated by the terminal user to a counterpart terminal; And a third process of switching the video call screen based on the screen mode set in the screen mode control message at the counterpart terminal receiving the screen mode control message.
According to a video call screen mode control system and method of the present invention, a video service screen mode of a terminal connected to a video call call is controlled by a video service server so that video data provided by a video service server is displayed on the entire screen. The terminal connected to the server can effectively check the image provided by the image service server.
Further, by controlling the video call screen mode of the counterpart terminal in which the video call is set in the terminal of one side, the video call screen mode of the counterpart terminal can be controlled according to the image provided from the terminal of the one side to the counterpart terminal.
Hereinafter, a video call screen mode control system and method according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.
2 is a road showing an example of a mobile communication network including a video call screen mode control system according to an embodiment of the present invention, the video call screen mode control system according to the present invention includes a WCDMA network LTE (Long) It can be applied to all networks capable of video call such as Term Evolution (HSDPA) network, HSDPA (High Speed Downlink Packet Access) network, CDMA 2000 1x EV-DO network, IP network.
