## Abstract

A method for identifying a device comprising generating, by a control device, an identification identifier of a multimedia device according to device description information of the multimedia device, sending the identification identifier to the multimedia device, so that the multimedia device displays the identification identifier, acquiring, by the control device, the identification identifier displayed by the multimedia device and an appearance image of the multimedia device, and acquiring the device description information according to the identification identifier displayed by the multimedia device, and associating, by the control device, the device description information with the appearance image of the multimedia device, so that a user equipment identifies the multimedia device according to the appearance image.

## Claims

### Claim 1

A method for identifying a device, comprising:
generating, by a control device, an identification identifier of a multimedia device according to device description information of the multimedia device, wherein the multimedia device is an audio device, and wherein the identification identifier is at least one of preset music and a sound with a preset frequency;
sending, by the control device, the identification identifier to the multimedia device, so that the multimedia device displays the identification identifier;
acquiring, by the control device, the identification identifier displayed by the multimedia device and an appearance image of the multimedia device;
acquiring, by the control device, the device description information according to the identification identifier displayed by the multimedia device; and
associating, by the control device, the device description information with the appearance image of the multimedia device, so that a user equipment identifies the multimedia device according to the appearance image.

### Claim 2 (depends on 1)

The method according to claim 1, wherein acquiring, by the control device, the device description information according to the identification identifier displayed by the multimedia device comprises determining, by the control device, that the identification identifier displayed by the multimedia device is consistent with the identification identifier generated by the control device.

### Claim 3 (depends on 1)

The method according to claim 1, before generating, by the control device, the identification identifier of the multimedia device according to the device description information of the multimedia device, the method further comprises acquiring, by the control device, the device description information and device capability information of the multimedia device.

### Claim 4 (depends on 1)

The method according to claim 1, wherein generating, by the control device, the identification identifier of the multimedia device according to the device description information of the multimedia device comprises generating, by the control device, the identification identifier of the multimedia device according to a universally unique identifier (UUID) and an internet protocol (IP) address of the multimedia device in the device description information of the multimedia device, and wherein associating, by the control device, the device description information with the appearance image of the multimedia device comprises associating, by the control device, the UUID and the IP address with the appearance image of the multimedia device.

### Claim 5 (depends on 1)

The method according to claim 1, wherein acquiring, by the control device, the appearance image of the multimedia device comprises acquiring, by the control device, the appearance image of the multimedia device by using a camera.

### Claim 6

A method for identifying a device, comprising:
receiving, by a multimedia device, an identification identifier of the multimedia device from a control device, wherein the multimedia device is an audio device, and wherein the identification identifier is at least one of preset music and a sound with a preset frequency; and
displaying, by the multimedia device, the identification identifier, so that the control device acquires device description information of the multimedia device according to the identification identifier and associates the device description information with an appearance image, wherein the identification identifier is generated by the control device according to the device description information of the multimedia device.

### Claim 7

A control device, comprising:
a generating module configured to:
generate an identification identifier of a multimedia device according to device description information of the multimedia device, wherein the multimedia device is an audio device, and wherein the identification identifier is at least one of preset music and a sound with a preset frequency; and
send the identification identifier to the multimedia device, so that the multimedia device displays the identification identifier;
a first acquiring module configured to acquire the identification identifier displayed by the multimedia device and an appearance image of the multimedia device;
a second acquiring module configured to acquire the device description information according to the identification identifier displayed by the multimedia device; and
an associating module configured to associate the device description information with the appearance image of the multimedia device, so that a user equipment identifies the multimedia device according to the appearance image.

### Claim 8 (depends on 7)

The control device according to claim 7, wherein the second acquiring module is further configured to:
determine that the identification identifier displayed by the multimedia device is consistent with the identification identifier generated by the control device, and
acquire the device description information corresponding to the identification identifier generated by the control device.

### Claim 9 (depends on 7)

The control device according to claim 7, further comprising a determining module, wherein before the identification identifier of the multimedia device is rated according to the device description information of the multimedia device, the determining module is configured to acquire the device description information and device capability information of the multimedia device.

### Claim 10 (depends on 7)

The control device according to claim 7, wherein the generating module is further configured to generate the identification identifier of the multimedia device according to a universally unique identifier (UUID) and an internet protocol (IP) address of the multimedia device in the device description information of the multimedia device, and wherein the associating module is further configured to associate the UUID and the IP address with the appearance image of the multimedia device.

### Claim 11 (depends on 7)

The control device according to claim 7, wherein the first acquiring module is further configured to:
acquire the identification identifier displayed by the multimedia device; and
