Abstract

A display device includes a display section configured to perform display and provided with a display screen; communicating sections configured to perform communication to receive pieces of content data from supply devices, respectively; and a controller configured to cause the received pieces of content data to be simultaneously displayed on corresponding divided areas of the display screen and to control the communicating sections to transmit, to the supply devices. The notification indicates that the pieces of content data are simultaneously displayed on the corresponding areas.

Claims

means for causing the received pieces of content data to be simultaneously displayed on corresponding divided areas of the display screen and for controlling the multiple communicating means to transmit, to the supply devices, a notification indicating that the pieces of content data are simultaneously displayed on the corresponding areas.

2. The display device according to claim 1, wherein, when the pieces of content data are simultaneously displayed on the corresponding areas, the controlling means controls the multiple communicating means to transmit, to the supply devices, a command for suspending superimposition of a control representation on video data of the content data.

3. A display method comprising the steps of:

receiving, using multiple means for performing communication, pieces of content data from supply devices, respectively;

simultaneously displaying, on corresponding divided areas of a display screen of displaying means, the pieces of content data received in the receiving step; and

transmitting a notification to the supply devices by using the multiple communicating means, the notification indicating that the pieces of content data are simultaneously displayed on the corresponding areas.

4. A computer-readable storage medium that stores a program for causing a computer to execute the steps of:

receiving, using multiple means for performing communication, pieces of content data from supply devices, respectively;

simultaneously displaying, on corresponding divided areas of a display screen of displaying means, the pieces of content data received in the receiving step; and

transmitting a notification to the supply devices by controlling the multiple communicating means, the notification indicating that the pieces of content data are simultaneously displayed on the corresponding areas.

5. A supply device comprising:

means for generating content data;

means for performing communication to transmit the content data;

means for superimposing a control representation on video data of the content data; and

means for controlling the superimposing means to suspend the superimposition of the control representation, on a basis of a notification that is transmitted from a display device having a display screen and that indicates that pieces of content data supplied from supply devices are simultaneously displayed on corresponding divided areas of the display screen.

6. A supply method comprising the steps of:

generating content data;

performing, using a communicating means, communication to transmit the content data;

superimposing a control representation on video data of the content data; and

performing control for suspending the superimposition of the control representation, on a basis of a notification that is transmitted from a display device having a display screen and that indicates that video of pieces of content data supplied from supply devices are simultaneously displayed on corresponding divided areas of the display screen.

7. A computer-readable storage medium that stores a program for causing a computer to execute the steps of:

generating content data;

performing communication, using means for performing communication, to transmit the content data;

superimposing a control representation on video data of the content data; and

performing control for suspending the superimposition of the control representation, on a basis of a notification that is transmitted from a display device having a display screen and that indicates that video of pieces of content data supplied from supply devices are simultaneously displayed on corresponding divided areas of the display screen.

8. A control system comprising:

supply devices, each including

means for generating content data,

means for performing communication to transmit the content data, and

means for superimposing a control representation on video data of the content data; and

a display device including

means for performing display, the means having a display screen,

multiple means for performing communication to receive pieces of content data from the supply devices, respectively, and

means for causing the received pieces of content data to be simultaneously displayed on corresponding divided areas of the display screen and for controlling the multiple communicating means of the display device to transmit, to the supply devices, a notification indicating that the pieces of content data are simultaneously displayed on the corresponding areas;

wherein each supply device further includes means for controlling the superimposing means to suspend the superimposition of the control representation, on a basis of the notification that is transmitted from the display device and that indicates that the pieces of content data are simultaneously displayed on the corresponding areas.

9. A display device comprising:

a display section configured to perform display, the display section having a display screen;

communicating sections configured to perform communication to receive pieces of content data from supply devices, respectively; and

a controller configured to cause the received pieces of content data to be simultaneously displayed on corresponding divided areas of the display screen and to control the communicating sections to transmit, to the supply devices, a notification indicating that the pieces of content data are simultaneously displayed on the corresponding areas.

10. The display device according to claim 9, wherein, when the pieces of content data are simultaneously displayed on the corresponding areas, the controller controls the communicating sections to transmit, to the supply devices, a command for suspending superimposition of a control representation on video data of the content data.

11. A display method comprising the steps of:
