Abstract : An efficient scheme of packet loss protection for transmission of JPEG2000 coded images, both for still images and video sequences, is proposed. The scheme utilizes FEC based packet loss recovery, the advantages of the JPEG2000 layered structure and codestream syntax, and a data embedding technique. Prior to transmission, packets containing the most significant layer of the codestream, which is related to a predetermined compression rate (bits/pixels) or minimum expected image quality, are strongly protected using FEC across packets. At the receiver, the redundant packets generated by the FEC code are utilized to reconstruct any lost packets of the most significant layer. The proposed scheme is backwardly compatible with a minimum standard decoder and introduces only a small number of redundancies.
