External input apparatus, communication terminal, display data sharing system and computer readable information recording medium

A display data sharing system comprising:

• a first communication terminal configured to deliver video data to a second communication terminal connected via a network;
• and
• an external input apparatus connected with the first communication terminal, wherein
• the external input apparatus comprises:
• a first display configured to display an image;
• circuitry configured to
• obtain image data of the image displayed on the first display,
• transmit the obtained image data to the first communication terminal, the first communication terminal being connected to a second display and an image capturing device, the second display displaying the video data which is delivered to the second communication terminal and which includes second image data captured by the image capturing device that is different than the image data displayed on the first display,
• receive, from the first communication terminal, display control information indicating whether or not the first communication terminal receives the image data transmitted by the external input apparatus for transmission to the second communication terminal as part of the video data, and
• update a menu to be displayed on the first display based on the received display control information, the menu indicating whether or not the image data is shared by the first communication terminal with the second communication terminal as part of the video data.

A non-transitory computer readable information recording medium storing a program executed by an external input apparatus which includes a first display configured to display an image and is connected with a first communication terminal that delivers video data to a second communication terminal connected via a network, the program when executed by the external input apparatus, causes the external input apparatus to perform a method comprising:

• obtaining image data of the image displayed on the first display,
• transmitting the obtained image data to the first communication terminal, the first communication terminal being connected to a second display and an image capturing device, the second display displaying the video data which is delivered to the second communication terminal and which includes second image data captured by the image capturing device that is different than the image data displayed on the first display,
• receiving, from the first communication terminal, display control information indicating whether or not the first communication terminal receives the image data transmitted by the external input apparatus for transmission to the second communication terminal as part of the video data, and
• updating a menu to be displayed on the first display based on the received display control information, the menu indicating whether or not the image data is shared by the first communication terminal with the second communication terminal as part of the video data.

A system which delivers video data to a communication terminal connected via a network, comprising:

• circuitry configured to:
• control display of an image corresponding to a first application in a first display area,
• obtain image data of the image,
• share the obtained image data with a second application, the second application corresponding to a second display area, the second application controlling display of the video data which is delivered to the communication terminal and which includes second image data captured by an image capturing device that is different than the image data displayed on the first display,
• receive, by the first application, display control information from the second application indicating whether or not the second application receives the image data for transmission to the communication terminal as part of the video data, and
• update a menu to be displayed on the first display area based on the received display control information, the menu indicating whether or not the image data is shared by the second application with the communication terminal as part of the video data.
