Abstract
Current television signals are converted into sequential scanning signals in a sequential scanning conversion circuit and supplied to a memory circuit. In the memory circuit, the sequential scanning signals are converted into interlaced scanning signals, and then the signals are time-compressed and converted into small screen signals. High-definition television signals decoded by a MUSE decoder are supplied to a selector as master screen signals. In the selector, the master and slave screen signals are selectively produced to form a picture-in-picture signal.
