Abstract
A method for reducing memory bandwidth in a video decoder begins by performing a data reduction operation on a decoded first coded image to produce a second set of image data. The second set of image data stored and is selectively used for subsequent image decoding, thereby reducing the memory bandwidth. The data reduction operation can include image downsampling, wherein the pixel density is reduced by a factor of two in each of the vertical and horizontal directions.
