Detecting device information including information about a device
First Claim
1. An apparatus which detects device information including information about a device, said apparatus comprising:
- a control unit which obtains first ID information specific to the device via a digital interface after second ID information is assigned to the device, wherein the first ID information includes the device information, and the second ID information is used for communicating with the device;
a memory which is coupled to the control unit, and stores the first ID information and the second ID information; and
a detecting unit which detects the device information from the first ID information,wherein if a new second ID information is assigned to the device, the control unit checks the new second ID information using the first ID information.

Abstract
The present invention provides for detecting device information including information about a device. First ID information is obtained which is specific to the device via a digital interface after second ID information is assigned to the device, wherein the first ID information includes the device information, and the second ID information is used for communicating with the device. The first ID information and the second ID information are stored in a memory. The device information is detected from the first ID information. A new second ID information is checked using the first ID information, if the new second ID information is assigned to the device.
