Communication method in a home network, network and device for implementing such a method
First Claim
1. A communication method in a first network comprising at least first and second devices connected to a communication bus, wherein, the first device includes an internet application and second device includes means for connecting to a second network comprising an internet network, said method comprises:
- sending a first request from said first device to said second device for opening a connection between said first and second devices;
sending an internet protocol request from said first device to said second device;
forwarding said internet protocol request from said second device to a third device comprising an internet server in said second network;
upon receipt, transferring a response from said third device in said second network to said first device through said second device over said communication bus; and
sending by the first device an internet application protocol identifier to the second device to identify an internet application protocol to be used between the first device and the third device in said second network for sending and/or receiving data, said internet application protocol being selected from among a plurality of protocols supported by the second device.

Abstract
The invention concerns a communication method in a home network comprising at least two devices connected to a communication bus, characterized in that, a first device including an internet application and a second device including means for connecting to the internet, said second device being able to manage at least one internet application protocol, said method comprises the steps of: sending a request from said first device to said second device for opening a connection between said first and second devices, wherein said request contains an internet application protocol identifier to identify the internet application protocol to be used over said connection; sending an internet protocol request under the format of said internet application protocol from said first device to said second device; forwarding said internet protocol request from said second device to an internet server; upon receipt; transferring a response from said internet server to said first device through said second device over said communication bus. The invention also concerns a network and a device for implementing the method above.
