Abstract: A dual conversion receiver architecture that converts a radio frequency signal to produce a programmable intermediate frequency whose channel bandwidth and frequency can be changed using variable low-pass filtering to accommodate multiple standards for television and other wireless standards. The dual conversion receiver uses a two stage frequency translation and continual DC offset removal. The dual conversion receiver can be completely implemented on an integrated circuit with no external adjustments.

Abstract: 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.

Abstract: A satellite reception assembly may comprise a memory collocated with a receive module and a basestation module. The receive module may receive a satellite signal and recover data carried in the satellite signal. The data may be stored in the memory. The stored data may be transmitted to mobile devices via the basestation module. Which portion of the recovered data is store in the memory may be based on demand for particular data in the coverage area served by the basestation module. Which portion of the recovered data is stored in the memory may be based on information provided by a satellite subscriber, such as the subscriber's anticipated location at one or more future time intervals.

Abstract: An automatic gain control loop disposed in a receiver is adapted to compensate for varying levels of out of band interference sources by adaptively controlling the gain distribution throughout the receive signal path. One or more intermediate received signal strength indicator (RSSI) detectors are used to determine a corresponding intermediate signal level. The output of each RSSI detector is coupled to an associated comparator that compares the intermediate RSSI value against a corresponding threshold. The take over point (TOP) for gain stages is adjusted based in part on the comparator output values. The TOP for each of a plurality of gain stages may be adjusted in discrete steps or continuously.
