ABSTRACT:
A video signal processor receives a digital video input signal containing I-data and other data in random positions in a data frame. A pre-processor separates the frames into the data components. A tessellation of a video screen containing vertical columns and horizontal rows is programmed into the pre-processor. The pre-processor assembles records with the I-data positioned in the records such that a video recorder head, scanning the data in any trick-mode speed, will update sequential rows or sequential columns of the tessellation according to the I-data.
