ABSTRACT:
A pix-in-pix television display includes a memory for holding samples representing one field of the small picture. Samples which are to be written into the memory are developed in a buffer memory one line at a time over intervals corresponding to the three line periods of the signal which produces the small picture. A line of samples is written from the buffer memory into the field memory over three line periods of the small picture signal. The memory write operation is suspended when data is read from the field memory for display. The write operation resumes when a read operation is completed at the address and pixel value which were being written when the write operation was suspended.
