ABSTRACT:
The present invention is a storage and retrieval system for JPEG images. In one illustrative embodiment the system includes an apparatus for storing a JPEG image in or on a storage medium with unequal error protection, comprising a separator for separating the JPEG image into Type-I and Type-II information, an error correction encoder for encoding the Type-I information with more error protection than the Type-II information, and a storage recorder for recording the encoded Type-I and Type-II information in or on the storage medium. The system further includes an apparatus for reading the encoded Type-I and Type-II information from the storage medium.
