    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: 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.

    摘要: A GNSS system operates intermittently and has adaptive activity and sleep time in order to reduce power consumption. The GNSS system provides an enhanced estimate of its position in the absence of GNSS signals of sufficient strength. The user's activity and behavior is modeled and used to improve performance, response time, and power consumption of the GNSS system. The user model is based, in part, on the received GNSS signals, a history of the user's positions, velocity, time, and inputs from other sensors disposed in the GNSS system, as well as data related to the network. During each activity time, the GNSS receiver performs either tracking, or acquisition followed by tracking. The GNSS receiver supports both normal acquisition as well as low-power acquisition.

    摘要: A filter for processing a digital TV composite signal having a video component and an audio component includes a digital video filter and a digital audio filter. The digital video filter includes a lowpass finite impulse response (FIR) filter, an up-mixer, an asymmetric filter for compensating a Nyquist slope of the video component, and a down-mixer connected in this order. The digital audio filter includes an audio down-mixer, a decimated FIR filter, an enhancing FIR filter, an interpolated FIR filter, and an audio up-mixer. These components are connected in series. Optionally, the decimating FIR filter is decimated by an integer decimation factor M, and the interpolated FIR filter is interpolated by an integer factor N. The integer M and N may have the same value.
