An MPEG compatible decoder receives encoded, compressed data in the form of image representative pixel blocks. The decoder includes a frame memory (20) for storing reconstructed pixel blocks incident to the decoding process. The previously decompressed data is re-compressed (30) before being written to the memory. Stored decompressed data is decompressed for display (34, 26), or as needed for decoding functions such as motion compensation processing (32, 22). The compression performed before writing data to memory is block-based compression using compressed data from one of two different compression paths (FIG. 3, 314, 320) which compress a given pixel block simultaneously. |

DETAILED DESCRIPTION In accordance with the principles of the present invention, it is herein recognized as desirable to manage the memory requirements of a digital image processing system efficiently, particularly in the case of MPEG compatible systems which may find extensive use in consumer products.
In an image signal decoder employing the principles of the present invention, previously decompressed image data is compressed before being written to memory used in the decoding process.
In a disclosed MPEG compatible decoder embodiment, the data is compressed before being written to image frame memory, and the stored data is decompressed for display or when needed for MPEG decoding functions such as motion compensation processing.
In accordance with a feature of the invention, the compression is block-based compression using compressed data from one of two different compression paths.
