System and method for establishing master component in multiple home networks
First Claim

1. A system communicating with a first home network, in a first dwelling, the first home network having plural components, one of which is a first master, the system further communicating with a second home network in a second dwelling, the second home network having plural components, one of which is a second master, the system comprising:
- a digital processing circuit executing in the first home network to transfer a master function away from the first master if the first master cannot detect the second master because signals between the masters are obstructed such that the first master no longer has any master function, wherein the first master transmits a query signal, and if the first master does not detect a response from the second master and a detecting component in the first home network detects a response from the second master, the master function is transferred to the detecting component, wherein the digital processing circuit resides on the first master, after transferring the master function away, assuming a role of slave searching for other masters;
wherein the first and second masters communicate with each other for bandwidth management;
wherein the components in the first home network communicate with each other over a power line communication network and the components in the second home network communicate with each other over a power line communication network.

Abstract
Which device in a first home network is a master device is dynamically established based on the device reporting successful communication with a master device in a second home network, to ensure that the networks have master devices that can “se” each other for, e.g., managing bandwidth.

1. A system communicating with a first home network, in a first dwelling, the first home network having plural components, one of which is a first master, the system further communicating with a second home network in a second dwelling, the second home network having plural components, one of which is a second master, the system comprising:

a digital processing circuit executing in the first home network to transfer a master function away from the first master if the first master cannot detect the second master because signals between the masters are obstructed such that the first master no longer has any master function, wherein the first master transmits a query signal, and if the first master does not detect a response from the second master and a detecting component in the first home network detects a response from the second master, the master function is transferred to the detecting component, wherein the digital processing circuit resides on the first master, after transferring the master function away, assuming a role of slave searching for other masters; wherein the first and second masters communicate with each other for bandwidth management; wherein the components in the first home network communicate with each other over a power line communication network and the components in the second home network communicate with each other over a power line communication network. - View Dependent Claims (2)

3. A logic device, comprising:
- a processor determining whether a master device in a first network adequately receives signals from a master device in a second network that shares bandwidth with the first network;
and the processor, responsive to a determination that the master device in the first network does not adequately receive signals from the master device in the second network, transferring at least one master device function to a component in the first network other than the master device in the first network, wherein the master device transmits queries to non-master devices in the first network, and each non-master device in the first network that receives a query reports to the master device including informing the master device if the non-master device has received signals from the second master, wherein if the master device in the first network receives a response from a first non-master device indicating that the first non-master device communicates with the second master, the master device transfers master functionality to the first non-master device, which becomes the new master device of the first network, wherein non-master devices in the first network do not appear in the second network, wherein after transferring the master function away, the master device assumes a role of slave searching for other masters, wherein the first and second networks are first and second PLC networks.
- a processor determining whether a master device in a first network adequately receives signals from a master device in a second network that shares bandwidth with the first network;
