  • Patent number: 9014014
    Abstract: Methods and systems for operating a physical layer device (“PHY”) in an Ethernet network include methods and systems for detecting active link partners and for selecting a mode of operation based on detected active link partners. The PHY monitors fiber link media and copper link media for active link partners. The PHY selects a mode of operation according to detected active link partners. For example, a copper mode of operation is selected, preferably through logic circuitry, when an active copper link partner is detected and an active fiber link partner is not detected. Similarly, a fiber mode of operation is selected, preferably through logic circuitry, when an active fiber link partner is detected and an active copper link partner is not detected. The PHY interfaces with the active copper link partner when the copper mode of operation is selected. Similarly, the PHY interfaces with the active fiber link partner when the fiber mode of operation is selected.

  • Patent number: 9015230
    Abstract: A gateway includes at least one communications interface and processing circuitry and establishes communications with at least one service provider device and with a serviced client device. The gateway receives serviced client device display structure instructions, first streamed content from a service provider device, and second streamed content from a cloud server, the second streamed content based upon an Internet session hosted by the cloud server. Based upon the serviced client device display structure instructions, the gateway combines the first streamed content with the second streamed content to form merged streamed content and transmits the merged streamed content to the serviced client device. In another operation the gateway forwards the first streamed content to a first client device and the second streamed content to a second client device based upon the serviced client device display structure instructions.

  • Patent number: 9013311
    Abstract: A Method and system for a RFID transponder with configurable feed point for RFID communications is provided. In this regard, an RFID transponder may receive RF signals via a leaky wave antenna and modulate an amplitude of a backscattered signal associated with the received RF signals by switching between a plurality of feed points of the leaky wave antenna to vary an input impedance of said RFID transponder. Each of the plurality of feed points may be located in a different position in the resonant cavity of the leaky wave antenna. The input impedance may be controlled by switching a load in and out of a receive path of the RFID transponder. The leaky wave antenna may be integrated within and/or on an integrated circuit, an integrated circuit package, or a combination thereof.

  • Patent number: 9013997
    Abstract: A data segment of a data packet destined for an egress port of an egress node may be received at a first ingress node. An egress statement vector and an ingress statement vector may be identified at the first ingress node. A determination may be made, based on the egress statement vector and ingress statement vector, whether the first ingress node is authorized to transfer the data segment to the egress port before the other data segments of the data packet are received at the first ingress node. The data segment may be transferred to the egress port before the other data segments of the data packet are received at the first ingress node when the determination indicates the first ingress node is authorized. The data segment may be stored in a buffer of the first ingress node when the determination indicates the first ingress node is not authorized.

  • Patent number: 9014276
    Abstract: A 3-dimensional (3D) video transmitter may be operable to encode a 3D video to generate a scalable video coding (SVC) base layer and a SVC enhancement layer. A first view such as a first high-resolution view and a second view such as a second high-resolution view of the 3D video in the SVC enhancement layer may be separate frames. A first half-resolution view and a second half-resolution view of the 3D video in the SVC base layer may be packed in a single frame. The first half-resolution view in the SVC base layer may be a base-layer reference for the first high-resolution view in the SVC enhancement layer for inter-layer prediction of spatial scalable coding. The first high-resolution view in the SVC enhancement layer may be an intra-layer reference for the second high-resolution view in the SVC enhancement layer for intra-layer prediction of temporal scalable coding.
