摘要： A power supply for a satellite receiver system includes a dual input supply voltage arrangement. When a higher output voltage is selected, a source of a lower supply input voltage is coupled to an input main current conducting terminal of a series pass transistor. On the other hand, when a lower output voltage is selected, a source of a lower supply input voltage is coupled to the input main current conducting terminal of the series pass transistor. A comparator senses a magnitude of an output voltage produced by the series pass transistor. When, as a result of an over current condition, the output voltage is lower than a reference threshold level, any selection of the higher output voltage is automatically overridden and the source of the lower supply input voltage, instead, is coupled to the input main current conducting terminal of the series pass transistor.

摘要： Hacking of a class of Set-Top Boxes known as Integrated Receiver-Decoders (IRDs) used to receive satellite broadcasts for display on television sets is prevented by use of connections to the reprogramming enable pin of a flash memory. If a user attempts to reprogram the boot sector of the flash memory in order to obtain free service via privacy, the set-top box is destroyed. The invention relates to the design and manufacture of IRDs that are resistant to hacking via unauthorized reprogramming.

摘要： The RF signals received from the LNB and the corresponding IF signal produced by the tuner may be offset in frequency due to reasons other than a frequency drift of the oscillator of the LNB, such as satellite transponder frequency adjustments made by the satellite transmission system. A tuner (9) includes a local oscillator (911) controlled by a controller. The controller (a) controls the frequency of the local oscillator (911); (b) stores digital nominal frequency representative words for respective ones of RF signals received; (c) stores digital offset representative words for respective ones of the RF signals; (d) determines a frequency offset of said carrier signal after a RF signal has been tuned; (e) updates all of the digital offset representative words in accordance with the frequency offset of the carrier; (f) derives the tuning representative word for an RF signal selected to be tuned by combining said nominal frequency representative word for the RF signal selected to be tuned with the previously updated offset representative word for the RF signal selected to be tuned; and (g) updates the respective digital offset representative word for an individual RF signal presently being tuned if correct tuning is not achieved with the previously updated offset representative word.

摘要： An RF multiple switching apparatus, such as one included in or coupled to a broadcast satellite signal receiver, having a plurality of multiple RF signal input ports for receiving respective ones of a plurality of RF signals, such as broadcast satellite television signals, utilizes a relative signal strength indicator, such as an automatic gain control signal, to determine the difference between the actual input signal that is present at one of the plurality of signal input ports and a false signal that appears to be present at another signal input port of the plurality of signal input ports due to the RF signal bleeding between the multiple signal input ports. During a setup configuration determination or routine, the switching apparatus steps through each RF signal input, extracts pertinent transmission network (such as a satellite transmission network) information, determines a relative signal strength indicator for the RF signal, and compares the obtained information. Setup data for each RF signal input is stored according to the comparison.
