## Abstract

An information processing apparatus which displays a video image on a display unit, comprises a communication unit configured to communicate with a display apparatus via a network, and a control unit configured to generate a video image for an extended display on which the display apparatus displays when the communication unit establishes a connection with the display apparatus, the video image being different from the video image displayed on the display unit.

## Claims

### Claim 1

An information processing apparatus which displays a video image on a display unit, comprising:
a communication unit configured to communicate with a display apparatus via a network; and
a control unit configured to generate a video image of an extended display to be displayed on the display apparatus when the communication unit establishes a connection with the display apparatus, the video image being different from the video image displayed on the display unit.

### Claim 2 (depends on 1)

The apparatus according to claim 1, wherein the control unit does not generate the video image of the extended display if a plurality of display units provided.

### Claim 3 (depends on 1)

The apparatus according to claim 1, wherein the control unit receives the resolution of the display apparatus from the display apparatus when the communication unit establishes a connection with the display apparatus.

### Claim 4 (depends on 1)

The apparatus according to claim 1, wherein the control unit determines the resolution of the video image of the extended display based on the resolution of the display apparatus and the resolution of video images that the control unit is able to generate.

### Claim 5 (depends on 4)

The apparatus according to claim 4, further comprising a plurality of display apparatuses;
wherein the control unit determines the resolution of the video image of the extended display based on the resolutions of the plurality of display apparatuses and the resolution of video images that the control unit is able to generate.

### Claim 6 (depends on 5)

The apparatus according to claim 5, wherein the control unit applies, as the resolution of the video image of the extended display, the resolution closest to the smallest resolution of the resolutions of the plurality of display apparatuses, from among the resolutions at which the control unit is able to generate video images.

### Claim 7 (depends on 5)

The apparatus according to claim 5, wherein the control unit applies, as the resolution of the video image of the extended display, the resolution closest to the largest resolution of the resolutions of the plurality of display apparatuses, from among the resolutions at which the control unit is able to generate video images.

### Claim 8 (depends on 1)

The apparatus according to claim 1, wherein the control unit discards the video image of the extended display if a connection with the display apparatus is interrupted.

### Claim 9 (depends on 5)

The apparatus according to claim 5, wherein, if a new information processing apparatus participates in a group to which the plurality of display apparatuses belong and with which a connection is established by the communication unit, the control unit transfers a video image of an extended display generated at the new information processing apparatus to at least one of the plurality of display apparatuses.

### Claim 10 (depends on 1)

The apparatus according to claim 1, wherein the control unit captures and transmits the video image of the extended display to the display apparatus.

### Claim 11

A method of controlling an information processing apparatus that includes a communication unit configured to communicate with a display apparatus via a network and display a video image on a display unit, the method comprising:
generating a video image of an extended display to be displayed on the display apparatus displays when the communication unit establishes a connection with the display apparatus, the video image being different from the video image displayed on the display unit.

### Claim 12

A non-transitory computer-readable storage medium storing a program for causing a computer to execute a method of controlling an information processing apparatus that includes a communication unit configured to communicate with a display apparatus via a network and display a video image on a display unit, the method comprising:
generating a video image of an extended display to be displayed on the display apparatus displays when the communication unit establishes a connection with the display apparatus, the video image being different from the video image displayed on the display unit.
