Abstract

The present invention relates to a method for providing information for power management of devices connected to a network. The present method creates a PM (Power Management) server list which includes, for at least one PM server, a pair of friendly names including a friendly name allocated to the PM server, and displays, for the at least one PM server, the other friendly name of the pair of friendly names, i.e., a friendly name allocated to an AV media server or an AV device instead of one friendly name allocated to the PM server in the event that information included in the created PM server list is provided to a user.

Claims

1. A method for preparing information for power management of devices on a network, comprising:

a step, conducted by a first application, for receiving name and network address from each of power management servers on the network and creating a power management server list;

a step for checking whether an address identical to the received network address is registered in a device list created by a second application; and

a step for, if registered, updating the power management server list such that information written in the device list is added to the power management server list.

2. The method of claim 1, wherein the network address is a unique address allocated to a communication module, physically connected to the network, for carrying out signal exchange.

3. The method of claim 2, wherein the unique address is MAC (Media Access Control) address.

4. The method of claim 1, wherein the first application is a control point for invoking an action for power management to the power management servers.

5. The method of claim 1, wherein the second application is a control point for invoking an action to AV devices on the network.

6. The method of claim 1, wherein the information written in the device list to be added to the power management server list is user friendly name assigned to an AV device.

7. The method of claim 6, wherein the updating step adds a user friendly name associated with the address on the device list identical to the received network address to the power management server list in association with a network address in the power management server list identical to the received network address.

8. A method for providing information for power management of devices on a network, comprising:

for at least one power management server, creating a power management server list which contains a pair of user friendly names including a user friendly name allocated to the one power management server; and

displaying, for the at least one power management server, one user friendly name of the pair of user friendly names instead of other user friendly name of the pair allocated to the one power management server, when displaying information of the power management server list.

9. The method of claim 8, wherein the one user friendly name to be displayed is a user friendly name allocated to an AV device on the network.

10. The method of claim 8, wherein the at least one power management server is a power management server integrated in a single embedded device together with other device.

11. The method of claim 10, wherein the other device is an AV media server.

12. The method of claim 8, further comprising, in response to a particular operation requested from selection of the one user friendly name displayed instead, invoking an action for asking a server, corresponding to the not-displayed other user friendly name of the pair to which the one user friendly name belongs, to carry out the particular operation.

13. The method of claim 12, wherein the particular operation includes inquiry about power status for power management and/or switchover between power statuses.
