ABSTRACT:
The operation of a tuner of a television receiver for tuning nonstandard, as well as standard, frequency RF television signals, requiring a relatively long time for completion, is partitioned into a number of shorter duration sections or "slices" which are individually time-multiplexed with other control operations under the control of a microprocessor. This allows the microprocessor to more frequently respond to new user initiated commands than otherwise possible. An interrupt subroutine of the stored program under which the microprocessor operates establishes time delays, required for the tuning system to settle before new operations are performed, outside the main control loop including the user command processing and tuner control subroutines so as not to slow the response of the microprocessor to user commands.
