An electronic apparatus having two or more functions includes a nonvolatile store in which the identities of two or more keys are stored and two or more functions are classified into groups, each group being distinguished by two or more of the keys. A controller is coupled with the nonvolatile store and enables a function that is selected by operating a key, which function matches an identification number to be entered by a user.

Knowledge-based access system for control functions

During channel selection on automatic fine tuning (AFT) operation is carried out over a period longer than one vertical scanning period.

Automatic fine tuning circuit

A television receiver and apparatus which includes a field memory which is capable of storing a video signal during a first period of time and includes a control for controlling the writing of the video signal in the image and also for displaying the stored video signal on the video screen intermittently.

Television receiver which includes a memory for storing a field image

A control system, for example, for a television receiver comprised of a monitor and a tuner has a plurality of sources of control commands, such as, remote control command receivers associated with the television monitor and tuner, respectively, and a manual control device or keyboard associated with the monitor, a plurality of input terminals connected to the control command sources, respectively, through independent paths and each of which is assigned a predetermined priority in relation to the other input terminals, and a controller for selecting one of the control commands in the order of the predetermined priorities assigned thereto when such control commands are simultaneously received at the respective input terminals, and for producing a control signal for the monitor and/or tuner in correspondence with the selected control command.

Control system having a plurality of control command sources

A switched power supply is connected to electronic circuitry the supply of power to which is to be controlled. An automatic switch enables the switched power supply selectively to energize or de-energize the electronic circuitry. A nominally continuous power supply is also provided, and a reset signal generator is connected thereto for generating a reset signal in response to a rising edge of an output voltage of the nominally continuous power supply following an interruption of the output voltage. A power switch is provided, together with a reset device actuated by the reset signal and a switching circuit controller connected to the automatic switch. A memory is connected to the switching circuit controller for memorizing the condition thereof and producing a memory output signal in response thereto. A detector detects the condition of the power switch and produces a detector output signal in response thereto. The switching circuit controller is connected to the reset device, the memory and the detector and generates a control signal for controlling the operation of the automatic switch in joint dependence on the memory output signal and the detector output signal when the reset device is actuated.
