摘要： 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.

摘要： According to the invention, there is provided a so-called picture-in-picture type television receiver in which a sub-picture screen is displayed within a main picture screen in a picture-in-picture fashion. When a picture based on a base band video signal from an external source such as a VTR, for example, is displayed on the sub-picture screen, if the sub-picture channel selecting means is then operated, the picture of a broadcast television channel is then automatically displayed on the sub-picture screen. This feature allows the omission of a video signal source switching means for the sub-picture, thus protecting the viewer from being confused when using the controls of the television receiver.

摘要： In a television receiver with a digital processing system for processing display parameters, a CRT discharge detector produces a signal in response to discharge of the cathode ray tube of the television receiver, and a control-reset circuit employs a signal for generating one or more reset pulses for holding the registers of the signal processing circuits in their reset state for the duration of the cathode ray tube discharge. Following termination of the discharge, the reset signal is removed which allows the signal processing circuits to resume their normal function with unaltered data.
