Abstract: Broadcast standard format video signals such as that adopted by the National Television Standards Committee (NTSC) or the European standard format of Phase Alternating Line (PAL) and some broadcast “compatible” video signals are used as inputs to a microkeyer to synchronize a microcomputer's display in a manner that allows full and complete merging of the two signals in the broadcast video domain by, for example, additive (mixing) or non-additive (keying) processes. The required synchronization in turn makes possible incorporation in any video space a variety of computer generated visuals such as illustrative graphics, titling and any other data displayed in the video. The merged video signal from this device may then be displayed on a television monitor, or transmitted, or received, or recorded by a video recorder or processed by a standard broadcast means for example. When applied to any common microcomputer display in its most fundamental form, no additional software is required.
