    摘要： A first device of a Multimedia Over Coax Alliance (MoCA) network may communicate with a second device of the MoCA network to control power-save operation of the second MoCA device. The first device may control the power-save operation of the second MoCA device based on an amount of data stored in a buffer, wherein the data stored in the buffer is destined for the second device. The buffer may be in a third device which sends the data to the second device, and/or the buffer may be in the first device. The first device may be operable to buffer data destined for the second device while the second device is in a power-saving state.

    摘要： Aspects of a method and apparatus for communicating electronic service guide information in a satellite television system are provided. A satellite communication system may receive a signal via an interface to a satellite dish, and receive data from a network via a second interface (e.g., an interface to a LAN or a WAN, such as the Internet). The satellite communication system may be operable to channelize the received satellite signal into a plurality of channels, wherein a first channel of the plurality of channels carries electronic service guide (ESG) data. The satellite communication system may select which of the plurality of channels to input to a demodulator based, at least in part, on whether ESG data is available via the second interface. A second channel carrying media data may be input to the demodulator while the ESG data is available via the second interface.

    摘要： A network device may be operable to manage a network connection of customer premise equipment (CPE). While the CPE is operating in a normal mode of operation, the network device may communicate with the CPE utilizing one or more messages of a first type. While the CPE is operating in a low-power mode of operation, the network device may communicate with the CPE utilizing one or more messages of a second type. The network device may be operable to determine a particular program identifier to be utilized for messages the first type of message, and transmit such message(s) to the CPE. The message(s) transmitted while the CPE is in a low-power mode may comprise MPEG-TS packets having the particular program identifier. The message(s) transmitted while the CPE is not in the low-power mode may comprises MPEG-TS packets not having the particular program identifier.

    摘要： To determine the level of frequency drift of a crystal oscillator as a result of a change in the its temperature, the temperature of the crystal oscillator is sensed and used together with previously stored data that includes a multitude of drift values of the frequency of the crystal oscillator each associated with a temperature of the crystal oscillator. Optionally, upon initialization of a GPS receiver in which the crystal oscillator is disposed, an initial temperature of the crystal oscillator is measured and a PLL is set to an initial frequency in association with the initial temperature. When acquisition fails in a region, the ppm region is changed. The temperature of the crystal oscillator is periodically measured and compared with the initial temperature, and the acquisition process is reset if there is a significant change in temperature. The GPS processor enters the tracking phase when acquisition is successful.

    摘要： A receiver can be configured to include an RF front end that is configured to downconvert a received signal to a baseband signal or a low Intermediate Frequency (IF) signal. The receiver can downconvert the desired signal from an RF frequency in the presence of numerous interference sources to a baseband or low IF signal for filtering and channel selection. The filtered baseband or low IF signal can be converted to a digital representation. The digital representation of the signal can be upconverted in the digital domain to a programmable IF frequency. The digital IF signal can be converted to an analog IF signal that can be processed by legacy hardware.
