Video signal control system

Claim 1

In a system for controlling electrical parameters requiring repetitive adjustments, apparatus for controlling a controlled parameter of of an event for each one of a plurality of events, comprising: operator signal means responsive to actuation by an operator for providing control signals indicative of a desired increase or decrease in the controlled parameter, said control signals being provided upon actuation from an indeterminate initial setting to a second setting displaced relative to said initial setting; addressable memory means, including a plurality of addressable memory locations, for storing said control signals in a predetermined one of said memory locations; mark signal means for providing a mark signal in response to actuation by an operator indicative that control signals provided by said operator signal means subsequent to said mark signal are associated with an event subsequent to said mark signal; and control means responsive to a first mark signal to cause said memory means to store control signals provided by the actuation of said operator signal means from said initial setting to said second setting in a first memory location associated with a first event, and further responsive to a second mark signal subsequent to said first mark signal to store control signals provided by the actuation of said operator signal means from said second setting to a third setting displaced relative to said second setting in a second memory location associated with a second event, whereby the apparatus is rendered operative to control the controlled parameter for said second event without requiring physical movement or physical resetting of the operator signal means from the second setting back to the initial setting.

Claim 8

An apparatus for operator control of an electrical parameter for a plurality of events without requiring physical movement or resetting of a control for each controlled event, comprising: operator control means for providing electrical control signals indicative of a desired increase or decrease in the controlled parameter in response to actuation by an operator; mark signal means for providing a mark signal in response to actuation by the operator; and control circuit means responsive to associate said control signals occurring in response to movement of said control means from an indeterminate initial position to a second position prior to said mark signal with a first controlled event, and to associate said control signals occurring in response to movement of said control means from said second position to a third position subsequent to said mark signal with a subsequent, second controlled event.

Claim 9

An apparatus for operator control of an electrical parameter for a plurality of events without requiring physical movement or resetting of a control for each controlled event, comprising: operator control means for providing electrical control signals indicative of a desired increase or decrease in the controlled parameter in response to actuation by an operator; mark signal means for providing a mark signal in response to actuation by the operator; and control circuit means responsive to associate said control signals occurring in response to movement of said control means from an indeterminate initial position to a second position prior to said mark signal with a first controlled event, and to associate said control signals occurring in response to movement of said control means from said second position to a third position subsequent to said mark signal with a subsequent, second controlled event.
