Abstract

The invention concerns a 1. Method for interfacing communication between a first device on a first network and a second device on a second network, the networks being connected by an interface device, the method being carried out by the interface device and being characterized by the steps of: detecting a first message on the first network, said first message being generated by the first device, said first message being relevant for the second device; translating the first message into a format compatible with the second device; sending a second message to the second device on the second network, the second message informing the second device that the first message has been detected; upon reception of a request from the second device, transmitting the translated first message. The invention also concerns a device for implementing the method.

Claims

1. Method for interfacing communication between a first device on a first network and a second device on a second network, the networks being connected by an interface device, the method being carried out by the interface device and comprising the steps of:

detecting a first message on the first network, said first message being generated by the first device, said first message being relevant for the second device;

translating the first message into a format compatible with the second device;

sending a second message to the second device on the second network, the second message informing the second device that the first message has been detected;

upon reception of a request from the second device, transmitting the translated first message.

2. Method according to claim 1, wherein the interface device further carries out the steps of

providing at least one applet, wherein said applet is adapted to receive the second message and to generate the request;

and

transmitting the applet to the second device.

3. Method according to claim 2, further comprising the step of

including the at least one applet into at least one html page, and transmitting the at least one page to the second device.

4. Method according to claim 3, wherein the step of translating the first message comprises the steps of updating at least one relevant object of the html page with parameters contained in the first message.

5. Method according to claim 2, further comprising the step of:

retrieving user interface elements of the first device;

translating the user interface elements into a format compatible for control of the first device through the second device;

including the translated user interface elements into the html page.

6. Method according to claim 5, wherein the step of translating the first message comprises updating at least one translated user interface element, based on parameters comprised in the first message.

7. Method according to claim 3, wherein the html page comprises at least one java object and/or at least one html object.

8. Method according to claim 3, wherein the step of sending the second message to the second device comprises performing a remote method invocation call to the applet, the remote method of the applet being such as to trigger an appropriate request from the second device to the interface device for transmission of the translated first message.

9. Method according to claim 8, wherein the request comprises one of the following:

an HTML GET message, a remote method invocation call to the interface device.

10. Method according to claim 2, wherein the applet is adapted to regularly poll a predetermined port of the interface device for determining whether a translated message is available at the interface device.

11. Method according to claim 1, wherein the request for transmission of the translated first message comprises one of the following:

a request to transmit an update of part of an html page;

or

a request to transmit an update of an entire html page;

or

a request to transmit an update of a java object or an HTML object.

12. Method according to claim 1, the first network is a HAVi network.

13. Method according to claim 1, wherein the second network is an Internet Protocol based network.

14. Method according to claim 1, wherein the first network is an Internet Protocol based network and the step of receiving the first message comprises receiving said message on a predetermined port from an applet in the first device.

15. Method according to claim 1, wherein the first network is an Internet Protocol based network and the step of receiving the first message comprises receiving said message through a remote method invocation call performed by an applet in the first device.

16. Device for interfacing communication between a first device on a first network and a second device on a second network, said device comprising

means for detecting a first message on the first network, said first message being generated by the first device, said first message being relevant for the second device;

means for translating the first message into a format compatible with the second device;

means for sending a second message to the second device on the second network, the second message informing the second device that the first message has been detected and upon reception of a request from the second device, transmitting the translated first message.

17. Device according to claim 16, further comprising memory for storing user interface element representations for user interface elements of devices of the first network for control by devices of the second network and vice-versa, and means for translating the user interface elements of the first device according to the representations, for transmission of the translated elements to the second device, wherein the translation means are adapted to translating actions performed on one device or notifications generated by one device to a format compatible with the other device.

18. Method for interfacing communication between a first device on a first network and a second device on a second network, the networks being connected by an interface device, the method being carried out by the interface device and comprising the steps of:

detecting a first message on the first network, said first message being generated by the first device, said first message being relevant for the second device;

translating the first message into a format compatible with the second device;

transmitting the translated message to the second device,

wherein the first and second networks are IP and HAVi networks or vice-versa, and wherein the message is a notification or an action.

19. Method according to claim 18, wherein the exchange of a notification or action between the interface device and a device on an IP based network is carried out through a remote method invocation call.

20. Method according to claim 19, wherein the transmission of a notification from the interface device to the second device on an IP based network includes having the second device regularly poll a fixed port of the interface device acting as a server.
