摘要： A pix-in-pix television display, with a digital memory for holding samples representing one field of the small picture, includes circuitry for converting eight-bit luminance samples into five-bit samples for efficient storage in the digital memory. A subtracter subtracts a predetermined block level bias value from each sample and an adder adds a two bit psuedo-random dither value to each sample. The six most significant bits of these samples are applied to a limiter which changes the samples having values greater than thirty-one to have values of thirty-one. The five-bit luminance samples are obtained by taking the five least significant bits of the samples provided by the limiter.

摘要： A communications system for conveying information angle-modulated onto a carrier includes a modulator which angle-modulates the data onto the carrier and which also randomly changes the phase of the carrier. Since the carrier phase is randomly changed, an unauthorized receiver or interceptor of the signal who frequency-multiplies the signal and integrates over a long period in order to reconstruct the carrier produces a carrier which has a broader bandwidth and relatively less amplitude than in the case in which the carrier phase is not randomly changed. The probability of intercept and demodulation by the unauthorized receiver is thereby reduced. The authorized receiver frequency-multiplies and integrates for the known frame interval to recover the carrier.

摘要： Integrated circuitry including at least one electrically erasable electrically programmable latch circuit. The contents of each latch circuit can be altered by applying programming voltages to the same terminals of the integrated circuitry that are used for other functions during times of normal operation. Each latch circuit provides localized memory for controlling the configuration of the integrated circuitry during times of normal operation, rather than depending upon memory external to the integrated circuitry for controlling the configuration of the integrated circuitry.

摘要： A digital deghosting system uses the interval between the sixth pre-equalization pulse and the first serration as a training signal to determine the timing and amplitude of ghost signals relative to the desired signal. The system includes level shifting circuitry to change the amplitude of the video signals during the training interval. This amplitude shift ensures that all of the information concerning the ghost signals is within the dynamic range of the analog to digital converter.

摘要： A CCD parallel-to-serial converter comprising two successions of charge transfer stages, recurrently side-loaded with respective ones of parallelly supplied charge packets, then serially unloaded by time-interleaved respective shift register operations. The charge packets converted to time-division-multiplexed serial form are supplied to a shared electrometer, and the electrometer response is de-multiplexed. Preferably, shift register operations are carried forward concurrently at the same rate, but with the final charge transfer stages clocked in phases staggered in time.

摘要： A video component interconnection system includes a single signal conductor video bus serially coupled between each of the video components for conducting video signal between the components. A switch located in series with the video bus separates the continuity of the video bus when it is non-conductive. A shunt switch arrangement coupled to the video bus at its junction with the series switch, applies an impedance substantially equal to the characteristic impedance of the video bus between the video bus and a reference potential, when the series switch separates the continuity of the video bus, in order to reduce ghost-producing reflections.

摘要： A television deflection apparatus includes a deflection winding coupled to a retrace capacitance to form a retrace resonant circuit. A power transistor switch is coupled to the retrace resonant circuit for generating alternating current in the retrace resonant circuit. The power transistor switch energizes a primary winding of a flyback transformer that supplies a first voltage across a secondary winding of the flyback transformer. The first voltage is coupled to an inductance for forming an upramping current in the inductance. The upramping current in the inductance is coupled to the base electrode of the power transistor switch, causing the power transistor switch to be conductive during the second half of trace. A second switch, that is responsive to a deflection rate input signal, couples to the base electrode of the power transistor switch a negative supply voltage that turns off the power transistor to initiate the retrace interval.
