## Abstract

A method for intelligent screen sharing, a screen sharing application and a system for multi-party and multi-media conferencing can be configured to allow an efficient temporary switching of screen sharing in a multi-party multi-media conference and/or automatically returning to previous presenter(s) without the need to restart the screen sharing again. In some embodiments, an automatic re-establishment of the screen sharing session can be provided as well (e.g. after a presenting user had temporarily lost network connection).

## Claims

initiating a second screen sharing in the screen sharing session of the screen sharing application service to share a screen content of the second user device of a second user during the screen sharing session;
checking, by the screen sharing application service, whether multi-screen sharing is allowed and/or provided for the screen sharing session;
pausing, by the screen sharing application service, the first screen sharing of the first user upon a determination that multi-screen sharing is not allowed and/or not provided for the screen sharing session;
sharing the screen content of the second user device in the second screen sharing during the screen sharing session such that the screen content of the second user device is shared during the screen sharing session with at least the first user device to display the screen content of the second user device via the first user device;
ending the second screen sharing during the screen sharing session;
automatically resuming, by the screen sharing application service, the first screen sharing of the share screen content of the first user device during the screen sharing session; and
sharing, by the first user device, the screen content of the first user device after the first screen sharing is resumed.

### Claim 2 (depends on 1)

The method of claim 1, wherein the at least one other user device of the screen sharing session includes a third user device, the method further comprises:
initiating a third screen sharing in the screen sharing session of the screen sharing application service to share a screen content of the third user device of a third user before the second screen sharing ends;
checking, by the screen sharing application service whether multi-screen sharing is allowed and/or provided for the screen sharing session;
pausing, by the screen sharing application service, the second screen sharing when multi-screen sharing is not allowed and/or not provided for the screen sharing session; and
sharing, the screen content of the third user device in the third screen sharing during the screen sharing session such that the screen content of the third user device is shared during the screen sharing session with at least the first user device and the second user device to display the screen content of the third user device via the first user device and the second user device.

### Claim 3 (depends on 2)

The method of claim 2, comprising:
in response to the third screen sharing stopping, automatically resuming, the first screen sharing and/or the second screen sharing according to one or more pre-defined screen sharing options.

### Claim 4 (depends on 3)

The method of claim 3, comprising:
after the automatic resumption of the second screen sharing, sharing the screen content of the second user device of the second user during the screen sharing session.

### Claim 5 (depends on 1)

The method of claim 1, comprising:
in response to determining that multi-screen sharing is allowed and/or provided for the screen sharing session, initiating a multi-screen sharing of the first user device and the second user device according to one or more pre-defined screen sharing options.

### Claim 6 (depends on 1)

The method of claim 1, comprising:
in response to the first screen sharing or the second screen sharing stopping due to a loss of network connectivity in which network connectivity is subsequently re-established after the loss of network connectivity during the screen sharing session, resuming, by the screen sharing application service, automatically back to the first screen sharing or second screen sharing which was stopped due to the loss of the network connectivity.

### Claim 7 (depends on 3)

The method of claim 3, wherein the one or more pre-defined screen sharing options comprises:
resuming, by the screen sharing application service, automatically back to the first user device which was an initial screen sharing user in the screen sharing session; or
resuming, by the screen sharing application service, automatically back to the first, second, third or any further user which was a latest previous screen sharing user in the screen sharing session; or
resuming, by the screen sharing application service, automatically back to the first, second, third or any further user appointed as a moderator of the screen sharing session or appointed as a main presenter for the screen sharing session.

### Claim 8 (depends on 3)

The method of claim 3, wherein the one or more pre-defined screen sharing options are carried out by means of a screen sharing historical data analytics application and/or a real-time, voice analytics application and/or a real-time video analytics application that are supported by artificial intelligence, machine learning and/or natural language processing.

### Claim 9 (depends on 3)

The method of claim 3, wherein the one or more pre-defined screen sharing options comprises:
resuming automatically back to screen sharing of the first, second, third or any further user device upon a detection and analysis of a key word or a key phrase by a real time voice analytics application and/or upon a detection and analysis by a video analytics application of a gesture and/or an enabling of video data by the first, second, third or any further user device.

### Claim 10 (depends on 1)
