ABSTRACT:
A method and system is disclosed for scaling computer video in the process of scan rate conversion. In the disclosed system and method storage is provided for at least two lines of graphics pixels per video component composing the computer graphics signals and less than a full frame's worth of the graphics pixels. The graphics pixels are stored as they are provided so that the newest graphics pixels or a linear combination of the newest graphics pixels and stored graphics pixels overwrite previously-stored graphics pixels. In a repeating pattern for every M television lines, where M>2, television pixels composing the television video signals are generated from a weighted sum of the stored graphics pixels such that a different precomputed set of weights are used to compute the television pixels for each of the M television lines. The television signals are horizontally and vertically scaled so the graphics image corresponding to the computer graphics signals being converted fits within a television display.
