摘要： A tuner includes a tunable filter for selecting a desired RF signal in response to a tuning control signal and a tunable image trap for rejecting the undesired image signal corresponding to the desired RF signal responsive to the tuning control signal coupled in cascade between an RF amplifier and a mixer. The tunable trap also serves as an impedance transformation element between the tunable filter and said mixer. The arrangement is particularly useful in a tuner in which the frequency range of the local oscillator signal is below the frequency range of the received RF signals.

摘要： A method for compatibly tuning a video signal receiver to an image processing device involves generating a prompting message for display to prompt a user to initiate a command response. First and second signals are generated. Each signal incorporates the prompting message but only one of the signals is compatibly tuned to the display. The first and second signals are alternately provided to the display and the prompting message is legibly displayed when the compatibly tuned signal is provided. The signal that is compatibly tuned to the display is selected in response to the command.

摘要： A satellite video receiver (12) for providing output signals to a television signal receiver (52) includes apparatus (10, 15, 16, 20, 45, 60, 65, 70) for operator selection of the modulator output channel frequency of the satellite receiver. The operator may select a modulator main channel, or an alternative manufacturer pre-set modulator default channel. In a first recovery mode, the operator may automatically replace an existing modulator channel with a manufacturer pre-set default channel, e.g., if a chosen main channel is forgotten. In another recovery mode, the operator may automatically re-establish a previously selected modulator main channel recalled from memory.

摘要： An economical tuning system for a digital satellite television receiver includes a phase locked loop (PLL) tuning control IC of the which is normally used in a tuning system of a conventional terrestrial broadcast or cable television reciever to control the frequency of the local oscillator (LO). Unfortunately, the PLL IC is only capable of changing the frequency of the LO in relatively large steps. As a result, the operation of a carrier recovery loop which demodulates the digitally encoded IF signal produced by the tuner may be interrupted during a fine tuning mode because the carrier recovery loop may not be able to track frequency changes of the LO. To reduce such possibility, the integrator filter associated with the PLL IC is modified to decrease the rate of change of the LO frequency during the fine tuning mode.
