    摘要： A television signal is encoded by the use of a sampling pulse synchronized with a color subcarrier frequency included in an input television signal, the encoded signal is compressed and recorded in a memory for later reproduction of a desired compressed picture image having a desired size and center position, the recorded signal is reproduced under the control of a clock pulse signal produced in synchronism with a sync signal obtained in a studio, for example, and the reproduced signal is corrected by inverting the polarity of the chroma component according to frame information at the time of recording of said reproduced signal.Thus, it is possible to freely obtain phase coupling of different synchronizing signals; for instance, it is possible to bring the phase of a different television signal of a different synchronization system into coincidence with the phase of a central synchronization signal and it is possible to reproduce an object image optionally compressed on a TV display screen.

    摘要： Chroma-signal processing system is disclosed wherein a color television signal is sampled at a frequency equal to a sub-carrier frequency multiplied by an integer, and chroma-components of the sampled signals are sequentially stored in a plurality of storage means for each of the sample points, and the chroma-signals are retrieved from the storage means while omitting portions of the chroma signals whereby accomplishing the chroma-signal processing with a fewer number of storage means. The system can be used to reduce the size of a displayed color image without introducing phase discontinuities into the chrominance subcarrier. The reduced image may then be inset into another color image displayed on a CRT. The system may also be used to reduce the subcarrier frequency of a chrominance signal.
