摘要： A picture quality circuit, in which a compensating signal for improving picture sharpness formed by second differentiating the input video signal is added to the input video signal. The input video signal is supplied to an adder (3). Simultaneously, the input video signal is supplied to a second differentiating circuit (4) to obtain a compensating signal S 1 . This compensating signal S, is fed to a white-side large amplitude suppressing circuit (6) to obtain a compensating signal S 3 . This compensating signal S 3 is fed to the adder (3) and added to the input video signal. This picture quality adjusting circuit makes it possible to suppress white peaks so as to prevent white-blurring and also to prevent the deterioration of black-side picture quality, and white-peak current is decreased so as to reduce the load on a Braun tube and deflecting system.

摘要： An amplitude-adjusting circuit used for a contrast-adjusting circuit of resistor division type in which a video signal is applied across a pair of series-connected resistors (23,251) and an output is produced from the junction point of the two resistors. At least one of the resistors is used as a variable resistor. The amplitude-adjusting circuit comprises a current source for supplying a constant current steadily between the terminals of the variable resistor, a high-gain amplifier (29) for controlling the resistance value of the variable resistor, and a filter (31, 33) for separating the video signal component from the change of the value of the variable resistor represented by a voltage change, and introducing the resistance change to the high-gain differential amplifier.

摘要： RF switching diodes in the antenna transfer switch of a video disc player are reverse biased by means of a bias supply when the main power supply of the player is turned off. The reverse bias counteracts any tendency for RF signals applied to the player antenna input connector from forward biasing the diodes which otherwise could result in intermodulation distortion of antenna input signals coupled to the player RF output connector. The effect of the reverse bias is augmented by a high pass filter in the antenna transfer switch which attenuates RF input signals at frequencies below the lowest assigned television channel frequency.

摘要： A television receiver includes a chassis having a digital tuner for generating local oscillator signals for tuning the receiver to respective channels in response to binary signals representing corresponding channel numbers and a signal processing unit for controlling at least one characteristic of the receiver such as the sound level, in response to binary signals representing the controllable characteristic. The receiver also includes a microcomputer including a RAM (Random Access Memory) with at least one memory location for storing binary signals representing the present time and a plurality of memory locations for storing binary signals representing future times and channel numbers of channels to be tuned at those times. A control portion of the microcomputer causes binary signals representing the channel number associated with a future time to be coupled to the digital tuner when the present time matches the future time. A keyboard having ten digit keys for generating binary signals representing the decimal digits between 0 and 9 and two characteristic keys to generate binary signal representing an increase and a decrease in the controllable characteristic is provided to enable user control of various operating modes of the receiver. When a user operates digit keys to form a number within a predetermined range of channel numbers, e.g., 2-83, the control portion of the microcomputer causes a channel to be tuned. Subsequently, operation of digit keys within the predeterined range of channel numbers causes the channel to be changed and operation of the characteristic keys causes the controllable characteristic to change. When a user operates digit keys to form a number not within the predetermined range of channel numbers, the control portion of the microcomputer causes power to be decoupled from the chassis. Subsequently, in response to the operation of a predetermined one of the characteristic keys, the control portion causes binary signals generated in response to the operation of the digit keys to be selectively coupled to either the RAM location associated with the present time or to the RAM location for future selections.

摘要： A reading pacer for educational television systems wherein blanking pulses of increasingly greater widths are employed to blank out successive lines of printed material appearing on a television screen starting from the top of the screen and progressing to the bottom. A ramp generator under the control of the viewer of the screen is used to control the generation of blanking pulses of successively greater widths and, hence, the rate at which successive lines of printed material on the screen are blanked out.
