摘要： A write PLL circuit generates a write clock signal for writing a video signal into a line memory. A readout PLL circuit generates a read clock signal for reading out the video signal stored in the line memory. An inner pincushion distortion correction voltage generation circuit modulates a correction waveform in the horizontal scanning period of time by a correction waveform in the vertical scanning period of time, to generate an inner pincushion distortion correction waveform, and adds a DC correction pulse to the inner pincushion distortion correction waveform and outputs the inner pincushion distortion correction waveform as an inner pincushion distortion correction voltage. A capacitive coupling circuit superimposes the inner pincushion distortion correction voltage on an output voltage of a loop filter of the readout PLL circuit, and feeds the inner pincushion distortion correction voltage to a VCO as a control voltage.

摘要： A video signal processing circuit synthesizes a video signal and a graphic signal on the basis of a display switching control signal, inverts a synthesized signal on the time axis for each of a forward scanning period and a backward scanning period, and output a display signal. A speed modulating signal control circuit inverts the binarized display switching control signal on the time axis for each of the forward scanning period and the backward scanning period, expands the pulse width thereof, and feeds the display switching control signal to a speed modulating signal generating circuit. The speed modulating signal generating circuit subjects a display signal to first-order differentiation, inverts the polarity of a differentiated signal in the backward scanning signal, sets a portion, corresponding to the graphic signal, in the differentiated signal on the basis of the display switching control signal at a zero level, and generates a speed modulating signal.

摘要： A video signal conversion part of a horizontal deflection circuit deletes a prescribed number of horizontal scanning lines from a vertical blanking interval of an input video signal and assigns a time corresponding to the deleted horizontal scanning lines to horizontal blanking intervals of the remaining horizontal scanning lines thereby extending the horizontal blanking interval of each horizontal scanning line and outputting a video signal. A synchronizing signal separation circuit extracts a horizontal synchronizing signal and a vertical synchronizing signal from the video signal output from the video signal conversion part. An output part of the horizontal deflection circuit supplies a sawtooth horizontal deflection current to a horizontal deflection yoke in synchronization with the horizontal synchronizing signal output from the synchronizing signal separation circuit.

The processor has a further arrangement such that, at the reception side, there are provided a circuit for separating the non-time-axis multiplexed signal, a circuit for separating a luminance signal and a chrominance signal, a circuit for demodulating the chrominance signal, a circuit for effecting time-axis compression, a circuit for time-axis expanding the time-axis multiplexed signal, and a circuit for time-axis compressing the non-time-axis multiplexed signal. A receiver provided with this processor may receive images broadcast under the existing television systems without troubles and also may reproduce TV images with a larger aspect ratio than the conventional 4:3 aspect ratio by the application of synchronous detection, time-axis compression, time-axis expansion, etc.

摘要： A video signal converter converts a video signal to a required form. The required form of the signal is the display format for displaying the signal. The input signal is converted to a digital signal and stored in a memory using the output of a first clock pulse generator synchronized to the horizontal synchronizing signal of the input signal. The digital signal is read out from the memory using the output of a second clock pulse generator synchronized to the vertical synchronizing signal of the input signal from a position specified by the controller. The output digital signal is then reconverted to an analog signal.

摘要： In the television broadcasting system called letter box method, it is proposed to transmit an image having a larger aspect ratio than that of the existing broadcasting system by using some of the scanning lines of the existing broadcasting system, and transmit some additional information signal in the remaining portion. An offset value applied to the additional information signal at the transmission side must be removed completely at the reception side. Accordingly, at the reception side, in the scanning line in which an offset reference signal indicative of the offset value is transmitted, the offset reference value and a DC level reference value of the scanning line are detected, and these values are retained until a next offset reference signal is detected. By detecting a DC level of a scanning line containing the additional information signal, a difference from the DC level reference value previously detected and retained is obtained, and the offset reference value detected and retained previously is corrected by this difference. Thus obtained offset value is subtracted from the transmitted additional information signal.
