  • Publication number: 20140128015
    Abstract: A direct sampling tuner includes a low noise amplifier and an optional dynamically configurable band pass filter coupled to the lose noise amplifier. The optional filter is configured to pass a selected band of channels. The tuner further includes a relatively high accuracy, multi-bit analog-to-digital converter (“ADC”) coupled to the LNA or to the optional dynamically configurable band pass filter. The ADC operates at greater than about twice a frequency of a sampled signal. The ADC directly samples the spectrum of the selected channels at the Nyquist rate, thus avoiding image problems presented by conventional tuners.

  • Publication number: 20140126395
    Abstract: Disclosed are various embodiments that relate to a network switch. The network switch obtains a network state metric, the network state metric quantifying a network traffic congestion associated with a switch. The network switch identifies a synchronous time stamp associated with the network state metric and generates an network state reporting message, the network state reporting message comprising the network state metric and the synchronous time stamp. The network state reporting message may be transmitted to a monitoring system.

  • Publication number: 20140127998
    Abstract: A communications device is disclosed that includes a united integrated circuit card (UICC) that provides a single wire protocol (SWP) current signal to a near field communications (NFC) device. The SWP current signal is filtered by a filter to remove noise from the SWP current signal. The filter is precharged by a reference voltage when the SWP current signal is in a low state and then filters the SWP current signal when the SWP current signal is in a high state. A switching network provides the filter with the reference voltage to precharge when the SWP is current signal is in the low state and then provides the filter with the SWP current signal to filter when the SWP current signal is in the high state.

  • Publication number: 20140125764
    Abstract: Methods, systems, and apparatuses are provided for enabling three-dimensional video and additional graphics to be displayed together without interference. A media content signal is received. The media content signal includes graphics overlay data representative of a graphics overlay, first image data representative of a first image, and second image data representative of a second image. The first and second images are representative of three-dimensional content. An interference is detected between the graphics overlay and the three-dimensional content in a three-dimensional view volume. At least one of the graphics overlay data, the first image data, or the second image data is modified to cause the graphics overlay and the three-dimensional content to be non-interfering. The non-interfering graphics overlay and three-dimensional content are enabled to be viewed by a viewer based on the modified graphics overlay data, first image data, and/or second image data.

  • Publication number: 20140126613
    Abstract: Methods, systems, and apparatuses are described for reducing the latency in a transceiver. A transceiver includes a high latency communication channel and a low latency communication channel that is configured to be a bypass channel for the high latency communication channel. The low latency communication channel may be utilized when implementing the transceiver is used in low latency applications. By bypassing the high latency communication channel, the high latency that is introduced therein (due to the many stages of de-serialization used to reduce the data rate for digital processing) can be avoided. An increase in data rate is realized when the low latency communication channel is used to pass data. A delay-locked loop (DLL) may be used to phase align the transmitter clock of the transceiver with the receiver clock of the transceiver to compensate for a limited tolerance of phase offset between these clocks.

    Abstract: A data rate control system for an optical line terminal (OLT) may include a processor, an OLT Medium Access Control (MAC) device that includes passive optical network (PON) ports that are mapped to identifiers, and a switch device coupled to the OLT MAC device. The OLT MAC device may determine that a PON port is congested, and may transmit a message to the switch device indicates the congestion at the PON port based on the mapped identifier. The switch device may transmit data items to the OLT MAC device for transmission over the PON ports at data rates respective to the PON ports, may receive the message, and may reduce the rate at which the data items are being transmitted to the OLT MAC device for transmission over the congested PON port without changing the rates at which other data items are being transmitted to the OLT MAC device.

  • Patent number: 8718084
    Abstract: A system and method for dynamic power control for energy efficient physical layer communication devices. Energy-efficiency features are continually being developed to conserve energy in links between such energy-efficient devices. These energy-efficient devices interoperate with many legacy devices that have already been deployed. In these links, energy savings can be produced by having a local receiver enter an energy saving state based upon the receipt of standard IDLE signals.

  • Patent number: 8717957
    Abstract: Preamble and header bit allocation for power savings within multiple user, multiple access, and/or MIMO wireless communications. Within a multi-user packet, information (e.g., partial address information) related to a recipient group of wireless communication devices (e.g., as few as one wireless communication device or any subset of a number of wireless communication devices, sometimes including all of the wireless communication devices) is emplaced within a PHY (e.g., physical layer) header of such a multi-user packet to be communicated within a multi-user (MU) environment. Such recipient indicating information can be encoded with relatively higher robustness (e.g., lower coding rates, lower ordered modulation, cyclic redundancy check (CRC), etc.) that remaining portions of the multi-user packet. Various portions of the remainder of the multi-user packet may respectively correspond to different wireless communication devices (e.g.
