Efficient packet loss protection for JPEG2000 images enabling backward compability with a standard decoder

This paper proposes an efficient packet loss protection strategy for transmission of JPEG2000 coded images over a packet erasure channel that backwardly compatible with the JPEG2000 part I decoder. The proposed scheme utilizes FEC at packet-level, the JPEG2000 layered structure and its error resilient functionalities. Prior to transmission. packets containing, initial layers of the codestream, which is associated to a minimum acceptable image quality are protected using a packet-level FEC. With a slight modification in the SOT marker segment and careful placement of the redundant packets, the generated codestream that carried redundant data is compliant with a standard decoder.
