A video demultiplexing interface (70) is used in a missile tracking system (10) employing a missile (12) with a thermal beacon (24). A target designator (40) defines a boresight from a missile firing location, such as an aircraft, to a target. The closed-loop tracking system (10) employs a forward looking infrared (FLIR) sensor (52) to track the displacement of the thermal beacon (24) from the boresight and generates a correction signal related to such displacement. The video demultiplexing interface (70) transforms serial multiplexed video signals, which are output by the FLIR sensor (52) and contain a field with M rows and L columns of pixels, into a demultiplexed parallel video signal containing N selectable adjacent horizontal rows of pixels (where N is less than M). A video thermal tracker (58) selects the N adjacent horizontal rows of pixels and generates azimuth and elevation error signals which are transmitted to the missile (12). The trajectory of the missile (12) is continuously corrected to align the thermal beacon (24) with the boresight.

[ What is claimed:] [1.] A video demultiplexing interface for transforming a serial multiplexed video signal, which includes a field having M horizontal rows and L columns of pixels which are output serially in a column-by-column manner, into a parallel video signal from which N adjacent horizontal rows of pixels can be selected, comprising:control means for generating channel select signals to select said N adjacent horizontal rows of pixels from said M horizontal rows, wherein N is less than M; andN sampling means, coupled to said control means, each for selecting successive pixels, from said field in said serial multiplexed video signal, which are from one of said N horizontal rows designated by said channel select signals.
