Abstract
Techniques for performing combined scaling, filtering, and/or scan conversion are disclosed that reduce that amount of line buffer space required in the overall design of a video processing system. In particular, coefficients from all or a sub-set of the scaling, filtering (smoothing/sharpening), and scan conversion filters are combined into one representative coefficient that can be applied in a single generic algorithm. Thus, implementation costs are reduced, particularly in system-on-chip implementations.
