## Abstract

An electronic device comprises: a plurality of scalers for processing respective images of a plurality of content received from a plurality of sources devices; and a processor configured to change information on whether at least one scaler of the plurality of scalers supports high dynamic range (HDR) when a request for simultaneously displaying the plurality of content is received.

## Claims

### Claim 1

An electronic device, comprising:
a plurality of scalers configured to perform image processing of a plurality of content received from a plurality of source devices, respectively; and
a processor configured to change, based on a request for simultaneously displaying the plurality of content being received, information on whether to support high dynamic range (HDR) of at least one scaler among the plurality of scalers.

### Claim 2 (depends on 1)

The electronic device of claim 1, wherein the information on whether to support HDR is comprised in Extended Display Identification Data (EDID) information of a corresponding scaler among the plurality of scalers.

### Claim 3 (depends on 2)

The electronic device of claim 2, wherein the processor is configured to:
change the information on whether to support HDR of the at least one scaler among the plurality of scalers to an HDR unsupported state.

### Claim 4 (depends on 3)

The electronic device of claim 3, further comprising:
a communication interface,
wherein the processor is configured to control the communication interface to transmit updated EDID information of each of the plurality of scalers to a corresponding source device among the plurality of source devices by changing to the HDR unsupported state.

### Claim 5 (depends on 2)

The electronic device of claim 2, wherein the EDID information is stored in an internal memory of the plurality of scalers respectively, or stored in an external memory outside of the plurality of scalers.

### Claim 6 (depends on 1)

The electronic device of claim 1, wherein the plurality of scalers are a plurality of first scalers and the electronic device further comprises:
a second scaler,
wherein the processor is configured to,
control the plurality of first scalers to perform image processing of the plurality of content received from the plurality of source devices based on size information that is same, and
control the second scaler to merge the plurality of content which is image processed by the plurality of first scalers.

### Claim 7 (depends on 6)

The electronic device of claim 6, wherein the size information comprises at least one from among resolution information, HDR information, high-bandwidth digital content protection (HDCP) information, color gamut information, or frame rate information.

### Claim 8 (depends on 1)

The electronic device of claim 1, wherein the request for simultaneously displaying the plurality of content comprises a user request for displaying the plurality of content in a picture by picture (PBP) form.

### Claim 9 (depends on 1)

The electronic device of claim 1, wherein the processor is configured to:
change, based on the request for simultaneously displaying the plurality of content being received and the information on whether to support HDR of the plurality of content being different, the information on whether to support HDR of the at least one scaler among the plurality of scalers.

### Claim 10 (depends on 1)

The electronic device of claim 1, wherein the electronic device and each of the plurality of source devices are connected to a size of High-Definition Multimedia Interface (HDMI) 2.1.

### Claim 11

A control method of an electronic device, the control method comprising:
receiving a plurality of content from a plurality of source devices; and
changing, based on a request for simultaneously displaying the plurality of content being received, information on whether to support high dynamic range (HDR) of at least one scaler among a plurality of scalers comprised in the electronic device.

### Claim 12 (depends on 11)

The control method of claim 11, wherein the information on whether to support HDR is comprised in Extended Display Identification Data (EDID) information of a corresponding scaler among the plurality of scalers.

### Claim 13 (depends on 12)

The control method of claim 12, wherein the changing comprises:
changing the information on whether to support HDR of at least one scaler among the plurality of scalers to an HDR unsupported state.

### Claim 14 (depends on 13)

The control method of claim 13, further comprising:
transmitting updated EDID information of each of the plurality of scalers to a corresponding source device among the plurality of source devices by changing to the HDR unsupported state.

### Claim 15 (depends on 12)

The control method of claim 12, wherein the EDID information is stored in an internal memory of the plurality of scalers respectively, or stored in an external memory outside of the plurality of scalers.
