Abstract
La presente invención se refiere a mejoras en dispato para procesar señales de video, que incluyen ce velocidad y de fase de un aparato reproductor de discos de video, que tiene una aguja captora de sde señales de video; una línea de retardo de señal giratorio, el aparato está sujeto a errores cíclicos en la velocidad de movimiento relativo entre ear una señal de control a partir de una porción prciones; un circuito de heterodinación acoplado a la aguja y que responde a las oscilaciones de la fuente una fuente de señales de referencia; un compaeñal de control, para producir una señal resultante; y un tercer circuito sumador para agregar algeb circuito de heterodinación, un trasductor estirad banda y la señal resultante, para producir una señal de salida a partir de canal de luminancia que copla el comparador de fase al transductor, para ra de frecuencia. parador de fase en un sentido que se opone a los errores en la velocidad de movimiento relativo; y un acoplador de señal adicional que acopla el comparador de fase a la fuente de oscilaciones, para controlar la frecuencia de las oscilaciones, de acuerdo con la salida del comparador de fase, en un sentido que tiende a mantener la sincronización de frecuencia y fase entre el componente cíclico en forma periódica de las señales transladadas en frecuencia y de las señales de referencia.The present invention relates to shooting improvements for processing video signals, including the speed and phase of a video disc player apparatus, having a video signal pickup needle; A rotary signal delay line, the apparatus is subject to cyclical errors in the relative speed of motion between hearing a control signal from a portion portion; a heterodyning circuit coupled to the needle and responsive to oscillations of the source a reference signal source; a control companion, to produce a resulting signal; and a third adder circuit to add the heterodyning circuit to the algeb, a band stretch transducer and the resulting signal, to produce an output signal from the luminance channel that couples the phase comparator to the transducer, for frequency ra. phase stopper in a sense that opposes errors in relative movement speed; and an additional signal coupler that couples the phase comparator to the oscillation source, to control the frequency of the oscillations, according to the phase comparator output, in a sense that tends to maintain phase and frequency synchronization between the cyclical component on a periodic basis of the frequency-translated signals and the reference signals.
