Screen sharing system and method for sharing screen

A screen sharing system for sharing a screen with a destination terminal by an operator terminal, comprising:

• a communication device;
• a display device;
• and
• a processor that
• receives an operation in a shared area where a screen is shared with the destination terminal;
• transmits, via the communication device, request data to request a change of a display format of screen data displayed in an area corresponding to the received operation to the destination terminal;
• receives, via the communication device, response data responding to the request from the destination terminal through a first communication channel being different from a second communication channel through which the screen data to be shared are transmitted, the response data being data in which the display format of the screen data is changed;
• changes the display format of the screen data displayed in the area corresponding to the received operation based on the received response data to generate a response screen;
• and
• displays, on the display device, the response screen together with the screen data of the area corresponding to the received operation.

A screen sharing system for sharing a screen with a destination terminal by an operator terminal, comprising:

• a communication device;
• a display device;
• and
• a processor that
• detects an area moving in a shared area where a screen is shared with the destination terminal;
• transmits, via the communication device, request data to request a change of a display format of screen data displayed in the detected area to the destination terminal;
• receives, via the communication device, response data responding to the request from the destination terminal through a first communication channel being different from a second communication channel through which the screen data to be shared are transmitted, the response data being data in which the display format of the screen data is changed;
• changes the display format of the screen data displayed in the detected area based on the received response data to generate a response screen;
• and
• displays, on the display device, the response screen together with the screen data of the detected area.

A method for sharing a screen with a destination terminal by an operator terminal, comprising the steps of:

• receiving a specified area of a predetermined area in a shared area where a screen is shared with the destination terminal;
• transmitting request data to request a change of a display format of screen data displayed in the received specified area to the destination terminal;
• receiving response data responding to the request from the destination terminal through a first communication channel being different from a second communication channel through which the screen data to be shared are transmitted, the response data being data in which the display format of the screen data is changed;
• changing the display format of the screen data displayed in the specified area based on the received response data to generate a response screen;
• and
• displaying the response screen together with the screen data of the specified area.
