Television receiver display apparatus having multi-image display capability

摘要

A television receiver display system for displaying, within a main image produced from a first video signal, one or more secondary images produced from a second video signal. Successive frames or fields of picture data of the second video signal are stored in an image memory, and successive lines of that data are read out to be alternately written into a pair of line memories, and subsequently alternately read out from the line memories in synchronism with the horizontal sync periods of the first video signal and at a higher data transfer rate than the write-in rate, to be then combined with video data of the first video signal and applied to a display.
