    • An apparatus is provided for synchronizing left-and right-eye images and for providing a composite video signal for a stereoscopic television system. The synchronization operation at a field-by-field rate is assured by detecting the phase-difference between a first vertical sync pulse which is derived from the vertical sync signal which is sampled by a horizontal sync signal and a second vertical sync pulse which is constantly delayed from the vertical sync signal of the composite video signal. As a result, the left eye image is always associated with the left eye lens of the viewer and the right eye image is always associated with the right eye lens of the viewer.

    • A frequency discriminating apparatus is constituted by a piezoelectric ceramic resonator, a reference capacitor, a pre-amplifier including a broad tuning circuit, a pair of amplitude detectors, and a differential amplitude limiter. The piezoelectric ceramic resonator is made of a piezoelectric lead titanate ceramic plate having a pair of electrodes covering the entire area of the major surfaces thereof, and the plate is poled with a poling field of not less than 50 kV/cm in the thickness direction. The thickness of the plate is chosen so as to cause the plate to vibrate in the thickness-extensional vibration of the 3rd harmonic overtone at a preselected frequency when an electrical signal is applied to the pair of electrodes. The differential amplitude limiter differentially adds the two signals detected by the two amplitude detectors and limits the peak output voltage amplitudes to a predetermined amplitude. The center frequency for the frequency discrimination by this apparatus can be stably maintained according to this apparatus, and the apparatus can be easily manufactured in the form of integrated circuits without necessitating many value adjustments of circuit elements.

    • A color television receiver receiving two television signals of different channels, compressing the time axis of one of the television signals, and inserting this compressed television signal in a portion of the other television signal for displaying the pictures of the two channels on the same screen. In the receiver, the luminance signal, chrominance signal and synchronizing signal are derived from each of the received two television signals. A writing clock pulse signal is produced on the basis of one of the synchronizing signals for writing the luminance signal and chrominance signal in the corresponding television signal in a memory circuit, while a reading clock pulse signal is produced on the basis of the other synchronizing signal to read out the luminance signal and chrominance signal from the memory circuit in a relation in which these signals are compressed in the time axis. After the luminance signal and chrominance signal read out from the memory circuit are adjusted in their signal levels relative to the luminance signal and chrominance signal in the other television signal, a portion of the luminance signal and chrominance signal in the other television signal is replaced by the luminance signal and chrominance signal read out from the memory circuit so that the pictures of the two channels can be displayed on the same screen.

    • A VTR signal discriminating apparatus for a television receiver generates discriminating signals when the receiver having this apparatus is receiving signals e.g. from a home use video tape recorder (VTR). This apparatus detects video head switching noises mixed in signals from the VTR having two video heads which are alternately switched every field of the signals by counting the number of apparent sync signals received within a given period of time. Thus, video signals originating from a broadcast station are distinguished from video signals originating from the VTR and the invention output denotes the presence of the appropriate signal. A television receiver can be modified in response to the invention output to accommodate the characteristics of the particular video signal received.
