摘要： Disclosed is a synchronizer for establishing synchronism between horizontal and vertical sync pulses of a non-interlaced video signal and those of an interlaced video signal, the number of non-interlaced scan lines being smaller by 2n-1 than the interlaced scan lines, where n is an integer equal to or greater than unity. Two variable frequency clocks are generated, one having a higher frequency variable as a function of a phase difference between the horizontal sync pulses of the two video signals and the other having one half the higher frequency. A first period is defined which runs from a non-interlaced horizontal sync of first occurrence in a given field to a horizontal sync of (n-1)th occurrence in the given field and a second period is defined that runs from the non-interlaced horizontal sync of first occurrence in a subsequent field to a horizontal sync of n-th occurrence in the subsequent field. The higher frequency clock is normally used to generate the non-interlaced horizontal and vertical sync and the lower frequency clock is used instead when vertical sync pulses of the two video signals are mismatched in phase and during the first and second periods to compensate for the difference in scan line number.

摘要： An information signal recording disc comprises a first recorded region in which an information signal at least including a video signal is recorded, and a second recorded region in which an end signal is intermittently recorded. The end signal is used to forcibly and automatically return a reproducing element of a disc reproducing apparatus from a playing position to a rest position. The second recorded region is provided at a position prior to the first recorded region in a direction of a reproducing sequence of the recorded signals on the information signal recording disc. The disc reproducing apparatus comprises a detecting circuit for detecting the reproduced end signal, and a controller. The controller controls the detecting circuit so that the detecting circuit is made substantially inoperative in a state where the disc reproducing apparatus is coupled to an external device having a discriminating function.

摘要： In a video recording system the chroma components of a color television signal are applied to a multiplexer where they are interleaved in frequency with each other so that the energy concentration of each chroma component occurs at frequencies interleaved with the frequencies at which the energy concentration of the other chroma component occurs. The interleaved chroma components and the luminance component are supplied respectively to frequency modulators each producing an output having energies distributed over the full range of the passband of the system. The outputs of the modulators are fed to first and second transducers for recording the luminance and chroma components on adjacent tracks of a recording medium.
