Abstract:
An audio distribution network for homes, businesses, apartments complexes, and other residential buildings is provided that performs audio distribution over a power line among one or more devices, with either the same audio content being sent to all devices, or different audio content being sent to different devices based on end-user input. This system and method provides for the management and control of these audio streams, as well as the bandwidth management of the power line network, to be performed by one device, or by a number of devices working in unison.
Abstract:
In a typical powerline communications environment, all electrical outlets and branches are connected to a load center. In this type of electrical system, all communication devices will share the same frequency spectrum, limiting the maximum bandwidth of the network, where all nodes are in contention with each other. In the inventive system, the electrical load center would provide filtering to isolate all branches off the load center into different network segments all capable of carrying the maximum bandwidth allowed by the physical layer technology. The advantages of the method described by this invention will be most noticeable when high bandwidth devices are communicating with each other on the same electrical segment, for example a HDTV receiver communicating with a HDTV monitor in the same room.
Abstract:
An integrated network adapter is operable to establish a network interface with a plurality of media types, including at least a power line network and a telephone line network, based on pre-configuration, upon initialization and dynamically during operation. The adapter further is operable to establish network interfaces simultaneously or separately with a plurality of media types and provide that a communications event can occur simultaneously or separately over a plurality of media types.
Abstract:
A power outlet adaptor device having a housing, at least one multimedia, networking and/or communications component, and an electrical socket box including at least one electrical socket is provided. The multimedia, networking, and/or communications component is secured within the housing and provides multimedia, networking and/or communications capabilities. The electrical socket accommodates an electrical device plug. The housing fits around the electrical socket box. The electrical socket box electrically couples to the multimedia, networking, and/or communications component.

Abstract:
A power line communications (“PLC”) transmitter and receiver device includes a physical communications protocol layer that provides for dynamic selection of a communications signal transmission operating mode from a plurality of such modes, where each has a corresponding transmission data structure that is based on characteristics of the electric power distribution network to which the PLC device is to be coupled and also the communications protocol profile requirements for the network.

Abstract:
A time synchronization beacon, which includes a plurality of timing signals at a plurality of different respective carrier frequencies, is synchronously transmitted over a power line network to synchronize consumption of media content data, such as audio data, which has been transmitted over the network from a power line communications (“PLC”) audio source to PLC equipped media content consumption devices, such as stereo audio speaker sets. The sets of speakers can be located in different respective rooms throughout a facility. The audio data can be in the form of network audio network data packets including one or more channels of audio data. The PLC consumption devices select which transmitted channel data is received and consumed. The beacon coordinates the start time of consumption of segments of audio data samples, and the sample-to-sample consumption time interval at PLC equipped consumption devices. The network packets can be addressed for desired PLC consumption devices using PLC network addressing methods.
Abstract:
Data throughput rate in a power line communications (“PLC”) system is controlled by generating PLC carrier signals in accordance with a PLC signal frame structure containing payload symbols where orders of modulation are selected for the individual PLC carriers based on evaluation of at least one of a PLC system channel quality and node configuration data. The selected orders of modulation determine the processing operations that a source PLC transceiver performs for generating PLC signals or that a destination PLC transceiver performs for extracting information content from received PLC signals. The orders of modulation can be selected to maximize the data throughput rate while maintaining compatibility with prior art PLC system protocols and standards that require a PLC signal frame structure and its payload portion to have fixed, predetermined lengths.
Abstract:
Powerline networks are inherently noisy and subject to power surges, spikes, and other events. Devices exist to combat these issues and protect electrical appliances that are connected downstream from the power sources for theses devices, but these devices usually also severely limit data communication that may also be desired on this network. This invention provides an intelligent, self-aware powerline conditioning and communication node that allows for, or even improves, data communication on the network, and still provides for noise reduction, line filtering, and surge protection for downstream electrical appliances.
