ADVANCE MEMORY REDUCTION SYSTEM FOR IMAGE PROCESSING SYSTEMS

摘要

An image processing system receives discrete cosine transform coefficient derived from decompressed MPEG-2 frames including I, P and B frames and applies a scalable tree encoding of the transformed coefficients. In this state, the I, P and B frames can be stored quickly and efficiently. When the frames are needed for further processing, the system decodes the coefficients and applies an inverse DCT to obtain the I, P and B frames. Then, the I, P and B frames may be passed to the MPEG-2 motion compensation algorithm for recovery of the original image frames and subsequent display.
