Abstract
A method and system for scaling frames of a compressed image stream, each frame including a mosaic of pixels. For each frame of the encoded image stream, the even-numbered lines of the frame are scaled as a first grouping of lines, while the odd-numbered lines of the frame are scaled as a second grouping of lines. This grouping of the lines of the frame may occur within the frame itself or by dividing the frame into sub-frames, in which case the even-numbered lines of the frame are scaled independently from the odd-numbered lines of the frame and a scaled version of the frame is then generated by merging the scaled even-numbered lines of the frame with the scaled odd-numbered lines of the frame.
