Abstract
Illustrated and described embodiments are broadly directed to novel systems and methods for generating a composite video signal from a plurality of independent video signals. In accordance with one embodiment, a method is provided for swapping from a secondary frame buffer of one of the plurality of computers. This synchnonization is performed by embedding a validity code having a first value in an overscan line of the video signal before beginning the swap and embedding a validity code having a second in the overscan line of the video signal after the swap is complete.
