Abstract: 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.

Abstract: A waveform display signal generating apparatus is provided in which a result of calculation processing of digital data in a CPU is visualized and is converted into a television video signal for display on a screen of a television receiver under production. The apparatus verifies digital data processing on a screen of a television receiver under production and provides a simplified verification system.

The data under digital signal processing is supplied to a CPU through a CPU interface circuit, is calculated for converting into a graph and then the converted data is stored in a RAM in a form of a bit map data. The bit map data is converted into an analog signal at a D/A converter, is further converted into a television video signal at a television encoder and then is supplied from a video signal output terminal to a video circuit of a television receiver under production.

Abstract: A recording/reproducing apparatus for recording and reproducing input signals having left and right stereo sounds. The stereo audio components of television signals prior to recording are data compressed and multiplexed. Then the stereo components are recorded in two channels, a left channel and a right channel. In playback, the audio signals are retrieved by the control signal from audio sound tracks of the recording medium.

Abstract: A scan converting apparatus receives an NTSC signal which is scan converted and which has a changed aspect ratio. The subtitle domain, which is vertically overscaned out of the screen and cannot be observed, is extracted and superimposed on the scan converted image. Scanning lines of a brightness output signal of a brightness/chrominance signal separator are interpolated at a scanning line interpolator and are converted to a system which has more scanning lines at a scanning line converter. An odd/even field discriminator prevents deterioration of the resolution of the subtitle letters which is caused by an interchange of the positions between two adjacent scanning lines when the subtitle is transferred to a different field. By stopping the writing of data to a field memory in the subtitle signal processor when a subtitle is transferred, a subtitle transfer can be accomplished even when there is no subtitle on the image.

Abstract: An I-axis phase pulse is allowed to be detected at the sampling point of a chrominance signal with a digitally-implemented circuit. A chrominance signal (sampling frequency f.sub.1) is subsampled by a frequency f.sub.2 (f.sub.1 /N) and subsampling pulses generated in N subsampling pulse generators 10 for N phases, the adjacent ones of the pulses being shifted by one clock (1/f.sub.1) with respect to one another. The subsampled chrominance signal is input to an I-axis determining circuit 17. The I-axis determining circuit operates to detect a maximum value M.sub.1 of a color burst signal (sampling frequency f.sub.1) and the data M.sub.2 after one clock and compare both of the values with each other. Based on the compared result, a selecting signal S.sub.4 is detected for selecting an I-axis phase pulse at the sampling point of the chrominance signal. A selecting circuit 18 selects, as an I-axis phase pulse S.sub.

Abstract: Disclosed is a noise reduction circuit in which a YC-separated luminance signal and a YC-separated chromaticity signal are separately processed for noise reduction. In the noise reduction circuit, delay elements incorporated in a YC separation circuit are also used as delay elements in a contour correction circuit so as to attain the desired purpose of noise reduction in both the luminance signal and the chromaticity signal and also the desired purpose of contour correction. Thus, both the noise reduction and the contour correction can be achieved by the noise reduction circuit which is simple in structure and inexpensive.
