Network device
First Claim
1. A digital device connected to a network, comprising:
- a device description for describing a digital device arrangement as predetermined information in order to utilize a function provided by the digital device from another digital device, corresponding to Plug and Play (PnP) capable of providing the function to the other digital device by communicating the predetermined information via the network by the digital device, and description restructuring means for updating the device description by detecting a change of an own device arrangement.

Abstract
There are disclosed a digital device in compliance with UPnP and its telecommunication method for restructuring a device description in accordance with a change of arrangements of own digital devices, such as a change of connection of extended peripheral devices, for example, and transmitting and reflecting a restructured device description to other digital devices. It is determined whether or not a change for the peripheral device of the own digital device is made by referring to a device information table stored in a memory for storing information for the peripheral device included in the own digital device. If it is determined that there is a change for the peripheral devices as a result, the device description is obtained and further a device name of the peripheral device associated with the change is obtained from the device information table. Then, the device description is updated by executing a procedure for information for the device description based on the obtained device name. Information for indicating a location for storing the updated device description, such as a new advertise message describing URL, for example, is transmitted from the own digital device to a network.

10. A method for processing information between a first device and a second device, wherein a device description for describing information for a structure of the peripheral device of the first device capable of connecting a peripheral device is transmitted to the second device via a network, and further a function of the peripheral device included in the first device can be utilized from the second device, comprising the steps of:
-
keeping information for the peripheral device included in the first device in a memory as a device information table;
referring to the device information table and determining whether or not a change is associated with the peripheral device of the first device;
if there is a change for the peripheral device as a result of determination, obtaining the device description and further obtaining a device name of the peripheral device for the change from the device information table;
updating the device description by processing information for the device description based on the obtained device name; and
transmitting information for indicating a location for storing the updated device description from the first device to the network. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A computer processable program for executing a method of reflecting a change for a peripheral device of a first device in a second device by transmitting a device description describing information associated with a peripheral device arrangement of the first device for allowing peripheral device connection to the second device via a network, comprising the steps of:
-
referring to device arrangement information stored in a memory for recording information associated with the peripheral device of the first device and determining whether or not the information indicates a change for the peripheral device of the first device;
if there is a change for the peripheral device as a result of determination, obtaining the device description and a device name of the peripheral device for the change from a device information table;
updating the device description by processing associated information for the device description based on the obtained device name; and
transmitting information for indicating a location for storing the updated device description from the first device to the network.
