According to an aspect, an apparatus may include a media streaming device including electronic circuitry configured to receive media content wirelessly from a media content source, and an audio output cord segment having a first end portion configured to be coupled to an audio input port of the media streaming device, and a second end portion configured to be coupled to an audio rendering device, where the electronic circuitry is further configured to transmit audio content through the audio output cord segment to the audio rendering device.

A method of managing communications between communication devices within a digital intercom system includes providing input and output tables for each communication device. The tables for each device are made up of cells formed from linear arrays corresponding to communication channels and the other devices. When two devices communicate on a given channel, a cell in the appropriate input and output table is identified based on the channel and the devices communicating. The cells provide volume control information which can be relied upon to determine if or to what degree audio signals should be transferred between the devices.

The technology provides for a power line communication system capable of providing data from a first device to a second device over a power line. The first device may include a set of contacts and a second device may include a second set of contacts. The second set of contacts may be adapted to electronically engage with the first set of contacts of the first device to form at least a power and ground lines connection. Circuitry within the first device and the second device may include circuitry for providing data over the power line connection between the first device and the second device. The circuitry may comprise a power line, a ground line, a transmitter line carrying data signals, a capacitor coupling the transmitter line to the power line at a connection point, and a receiver comprising two field effect transistors.

A digital intercom system includes a master station having hardware and software configured to allow duplex communication between a plurality of communication devices. The software runs a plurality of settings for directing communication between the communication devices. The master station is configured to modify the settings based on input entered into a browser based program run on an input/output (I/O) device by a user.

In one example, the present disclosure describes a device, computer-readable medium, and method for the delivery of video data and power via a single device port. For instance, in one example, a device includes a processor and a computer-readable medium storing instructions which, when executed by the processor, cause the processor to perform operations. The operations include receiving a power signal via a first port of the device, receiving a data stream via the first port of the device, and decoding the data stream to extract displayable content from the data stream.

Presented and described is, amongst other items, an intercom plug-in connector (10) for audio connections, comprising a cylindrical housing (19) extending in the axial direction (27), in particular with a circular, or essentially circular, cross-section, whose first axial end (20) is formed by a plug-in extension (22) that on its front face (39) has a plurality of sockets (23a, 23b, 23c, 23d), in particular four sockets positioned relative to one another in an approximately V-shape, for contact pins (24a, 24b), and which at its second axial end (21) has a phone jack (25) for a phone plug (14).

Embodiments are described for a hybrid amplification architecture that separates individual audio amplifier stages from the power supply and a simple two- or three-conductor bus that transmits both power and audio signal to a plurality of daisy-chained speakers to playback adaptive audio content in an expanded surround-sound environment including surround and overhead speakers or for use within professional live sound applications and/or distributed audio systems. A control unit generates digital audio and power and transmits both simultaneously over the bus to individual speaker units associated with each speaker. The speaker units recover the power decode the channel assignment to route the audio to the appropriate speakers.

A set-top-box (STB) provides capability for monitoring and control of power usage and the ability to establish communications. A smart residential service system (SRSS) is provided that uses power line communication (PLC) technology to provide secure in-home LAN communication and also to monitor and provide remote control of connected appliances in the home. An embodiment combines the STB with a master unit (MST) that is used with PLC to meet the requirements of the central device in the SRSS.

Exemplary embodiments of the present invention relate to a power line communication (PLC) system. For example, the PLC system may include a PLC server configured to provide electrical power and electronic communications through a PLC bus to a number of electronic devices, such as an instrument cluster, infotainment interface, rear-seat entertainment console, aftermarket accessories, and the like. The PLC system may also include a power system that may be coupled to an electrical grid for charging a battery associated with one or more of the electronic devices. The power system may be communicatively coupled to the PLC bus, enabling the devices coupled to the PLC bus to communicate with a service provider through the electrical grid. The communications between the devices coupled to the PLC bus and remote devices coupled through the electrical grid may be conducted using a common communication protocol.
