Title: Characterized fast tuning control for a television system

Granted: 1993-04-06
Abstract: CHARACTERIZED FAST TUNING            CONTROL FOR A TELEVISION SYSTEM               Abstract of the Disclosure A fast tuning subsystem for use in switching from a current channel to a selected channel of a television system includes a tuner for selecting a channel to be received, the tuner having a voltage controlled oscillator responsive to voltage applied to its control input for determining the channel frequency the tuner selectively receives.  Predictive means supplies a selected predicted voltage signal to the control input.  This predictive means has an associated memory in which is stored signals corresponding to respective voltage signals predicted for tuning to receive the channel frequencies of the respective channels.  A selected predicted voltage signal is applied to the control input to cause the selected predicted voltage signal to slew the channel frequency at a rapid slew rate to the frequency corresponding to the selected predicted voltage signal.  An error detector including a reference, generates a tuning error signal indicative of the tuning error of the tuner off the frequency for the selected channel.  Feedback combines the tuning error signal with the selected predicted voltage signal to provide a control signal at the control input for adjusting the channel frequency to reduce the tuning error.  The predictive means is substantially decoupled from the operation of the feedback means to prevent transients in the slew mode from substantially perturbing the feedback mode. Preferably, the subsystem utilizes a phase-locked loop in the feedback mode.  A method for predicting control voltages for a slew control for a fast tuning subsystem is also disclosed, preferably utilizing a combination of binary and linear search.
