Abstract
A color television receiver, having a tuner and associated demodulation circuits for both a main picture signal and a picture-in-picture (PIP) signal, uses a single memory for synchronization and for storing a single subsampled field of the PIP signal. Appropriate circuitry is included to selectively adjust the output of the memory to prevent the possible disorder of lines of the resultant PIP signal on display.
