ABSTRACT:
A multi-channel picture-in-picture television display system with a multi-channel method for controlling the selection of multiple channels for display within sub-screens of the main viewing screen is disclosed. Selection of multi-channel viewing is accomplished via remote control operation. Selection of still screen and moving screens is done by updating skip memory using an add key. Controlling a strobe signal of the system microcomputer generates a channel up/down command of a particular sub-screen during multi-channel operation.
