  • Patent number: 9544629
    Abstract: A video processing system located at a remote location such as a TV broadcasting station or an Internet media server stores a plurality of video elements at that are delivered to a viewing system located at a viewer's premises. The video processing system is capable of receiving a selection request comprising two or more video elements or subsets thereof, wherein the subsets are regions of interest or portions of the corresponding video elements. The video processing system constructs a custom video by combining them based on the viewer' selection and using the region of interest that are provided, and forwards the custom video to the viewing system. Billing based on record of usage is also supported for the custom video.

  • Patent number: 9544665
    Abstract: An device and method for providing multiple adaptive bit rate (ABR) streams using a single transcoder is disclosed. The device receives a group of content segments for a media channel, and converts, using a transcoder, a first of the content segments from a source format to a first data format, a first time duration for converting the first content segment being less than a second time duration for receiving each group of segments. The converted segment is then sent to a client device. On receiving a request from the device for content segments in a second data format, the device performs an initialization of the transcoder to convert content segments from the source format to the second data format, the initialization being completed during a residual period of time, or “operational gap” produced by a difference between the first time duration and the second time duration.

  • Patent number: 9543645
    Abstract: A transmitter front-end for wireless chip-to-chip communication, and for other, longer-range (e.g., several meters or several tens of meters) device-to-device communication is disclosed. The transmitter front-end can include a plurality of reflector power amplifiers implemented on an IC chip and an on-chip or on-package antenna for wireless transmitting a signal to another IC chip or device. The plurality of reflector power amplifiers can reflect the radiation of the on-chip or on-package antenna in a particular pattern such that the effective radiation pattern is reinforced in a desired direction and suppressed in an undesired direction. This helps to reduce the required output power of the transmitter front-end and mitigate interference with other potential wireless chip-to-chip or longer-range communications.

  • Patent number: 9542267
    Abstract: Aspects of enhanced recovery mechanisms are described. A predetermined operating parameter for a power rail is set at the outset of system start. Afterwards, a processor is released to start with a power management circuit. In turn, the power management circuit receives a default operating parameter for the power rail from the processor, and stores the default operating parameter. The power management circuit also receives a runtime operating parameter for the power rail from the processor and modifies the operating parameter for the power rail according to the runtime operating parameter. If an error condition in the processor is encountered, the power management circuit may modify the operating parameter for the power rail according to the default operating parameter in response to a reset control signal from the processor. Use of the default operating parameter for the power rail may assist the processor to recover from the error condition.

  • Patent number: 9544083
    Abstract: Methods and systems for removing interference from strongly powered SSS sequences in a received signal so that comparatively weakly powered SSS sequences in the received signal can be detected are disclosed. The methods and systems can perform a first cell search using the received signal to detect a strongly powered SSS sequence. Using a known SSS sequence corresponding to the strongly powered SSS sequence, the channel over which the strongly powered SSS sequence is received can be estimated. The estimated channel can then be used to determine the contribution of the strongly powered SSS and PSS sequence to the received signal so that it can be canceled. With the contribution of the strongly powered SSS and PSS sequence canceled from the received signal, a second cell search can be performed using the received signal to detect a weakly powered SSS sequence.

  • Patent number: 9544074
    Abstract: A system may time-shift the distribution high-definition (HD) audio. The system can obtain an audio stream from a specified audio source, transcode the audio stream into an HD audio stream, and store the HD audio stream in a memory. The system may later forward the stored HD audio stream to a destination device, which can be a communication device linked to the system through a local telephone network or a remote communication device. The system can also store HD audio when a local communication device receives an incoming call request that interrupts a current HD audio distribution process. The system may resume distribution of the HD audio after processing the incoming call request from a point when the distribution was interrupted.

  • Patent number: 9544091
    Abstract: A network device includes a communication interface and a transmitter coupled to the communication interface. The transmitter is configured to determine to start an auto-negotiation page with a link partner, and transmit, through the communication interface, a start delimiter for the auto-negotiation page. The transmitter transmits the start delimiter by transmitting a first pulse comprising a first encoding violation, followed by a second pulse comprising a second encoding violation. The transmitter may shorten the first pulse and the second pulse relative to a different pre-defined start delimiter to define spectral content for the first pulse and the second pulse that passes different first and second receiver filters in the link partner for different first and second communication standards.

  • Publication number: 20170005093
    Abstract: A field effect transistor (FET) configuration is provided having a gate region with a split work function for the source-side and drain-side of the gate region. The work function of a material is defined as the minimum energy required to extract an electron from the surface of the material to free space. Accordingly, the source-side portion of the gate region has a first work function that less than a second work function of the drain-side portion, the result of which is increased breakdown voltage at the drain-gate interface, without significantly increasing the threshold voltage of the FET. The split work function is achieved by layering n-type gate material over p-type gate material in the drain-side portion of the gate region, while only the n-type gate material us used in the source-side portion of the gate region.

  • Patent number: 9537781
    Abstract: Aspects of a method and system for an extended range copper transceiver are provided. Reducing the communication rate provided by multi-rate physical (PHY) layer operations in an Ethernet transceiver may extend the range of the Ethernet transceiver over twisted-pair copper cabling from a standard connection length. The Ethernet transceiver may support up to 1 Gbps or up to 10 Gbps transmission rate over copper cabling. The multi-rate PHY layer architecture in the Ethernet transceiver may support signal-processing operations, such as echo cancellation and/or equalization, which may be applied to the reduced communication rate to enable range extension. The reduced communication rate may be achieved by reducing the symbol rate provided by the multi-rate PHY layer operations. Reducing the communication rate may also enable utilizing greater insertion loss cabling for a standard connection length.
