Method of managing control right, client device therefor, and master device therefor

A client device mirroring a master device, the client device comprising:

• a transceiver;
• and
• at least one processor configured to control the transceiver to:
• request establishment of a mirroring connection with the master device,
• transmit a request to the master device for at least one right from among a plurality of rights for controlling the master device, and
• receive the requested at least one right from the master device in response to the request, wherein the requested at least one right is a first screen control right controlling a first screen region among the first screen and a second screen divided on a screen displayed on the master device,
• wherein the received at least one right is determined by the master device based on the request and another request for at least one right from among the plurality of rights which is transmitted from another client device to the master device, and
• wherein the requested at least one right is granted according to predetermined priorities of the plurality of client devices.

A method of managing a control right, the method being performed in a master device, the method comprising:

• establishing a mirroring connection with a plurality of client devices;
• receiving requests for rights from among a plurality of rights for controlling the master device from each of a first and a second client device among the plurality of client devices, wherein the rights comprise a first screen control right and a second screen control right;
• transmitting, to the plurality of client devices, a response for granting the requested rights to the first and second client devices among the plurality of client devices in response to each request;
• dividing a screen into at least two regions comprising a first screen region and a second screen region;
• and
• granting the first screen control right controlling the first screen region to the first client device and the second screen control right controlling the second screen region to the second client device,
• wherein granting the requested rights is according to predetermined priorities of the plurality of client devices.

A method of managing a control right, the method being performed in a client device which mirrors a screen displayed on a master device, the method comprising:

• establishing a mirroring connection with the master device;
• requesting, by the client device from the master device, at least one right from among a plurality of rights for controlling the master device;
• and
• receiving the requested at least one right from the master device in response to the request, wherein the requested at least one right is a first screen control right controlling a first screen region among the first screen and a second screen divided on a screen displayed on the master device;
• wherein the received at least one right is determined by the master device based on the request and another request for at least one right from among the plurality of rights which is transmitted from another client device to the master device, and
• wherein the requested at least one right is granted according to predetermined priorities of the plurality of client devices.
