    Abstract: Signals may be communicated between a video source and a video rendering device via and asymmetrical multi-rate Ethernet physical layer (PHY). The asymmetric multi-rate PHY may support multiple rates. The asymmetrical multi-rate Ethernet PHY may handle compressed and/or uncompressed, encrypted and/or unencrypted video signals and may handle audio/video bridging. One or more of the communicated signals may be modified by an echo cancellation operation, a near end cross talk (NEXT) cancellation operation, equalization, a far end cross talk (FEXT) cancellation operation and/or a forward error correction (FEC) operation. An aggregate communication rate may be evenly or unevenly distributed among one or more links coupling the video signal source to the video rendering device. A plurality of links coupling the video signal source to said video rendering device may also be aggregated.

    Abstract: A wireless communication device communicating with a serving base station in a wireless communication environment may have one or more applications running. When seeking to handover from the serving base station to a target base station, the wireless communication device adjusts the configurations of the applications based on the new communication link properties. Likewise, when an application is loaded that prefers communication link properties that exceeds a current communication link's capabilities, the wireless communication device may seek out and hand over to other communication links. By cooperatively coordinating the functionality of installed applications with communication link properties, the wireless communication device can maintain high levels of device and application functionality.

    Abstract: Systems and methods for providing dynamic substream definition and handover are provided. In embodiments, a user device includes a multiple radio access technology (RAT) communications modules and a communication controller. Each RAT communication module is further configured to communicate using a different RAT. The user device identifies available networks for communication. Then, the controller determines whether a need to split a communications stream exists (e.g., the user device is engaged in a bandwidth intensive application). If the communications stream is to be split, the controller defines the substreams (either equally or unequally) and assigns a first substream to a communication pathway in a first available network and assigns a second substream to a communication pathway in a second available network. The destination then recombines the substreams. In embodiments, the controller inserts synchronization in the substreams.

    Abstract: Systems and methods for staged connectivity and sleep mode are provided. Embodiments of the present disclosure optimize power consumption for a user across user devices by creating an ad hoc co-located network of user devices and establishing a device in the co-located network to act as a master (hub) device. In an embodiment, the system includes multiple user wireless devices and a network controller. The network controller identifies a set of proximate wireless devices and the power capability for each wireless device in the set. The network controller then selects a wireless device in the set to act as the hub (master) wireless device based on factors such as the power capabilities of each wireless device. The network controller then instructs the other wireless devices in the set to power down and instructs the appropriate network providers to handover communications to the hub (master) device.

    Abstract: Embodiments of the present disclosure provide systems and methods for reducing discovery time in a power over Ethernet (PoE) system where the nature of a load is known or can be safely assumed. By using prior knowledge of the nature of the load, the discovery procedure can be simplified. A power source device (PSE) controller measures a port voltage to determine if an open circuit exists or if a short circuit exists. If neither an open circuit or a short circuit exists, the system can be safely powered up.
