| Abstract(in English) | In this paper, we evaluated JPEG2000 error resilience tools over an orthogonal frequency division multiplexing (OFDM) channel. The error resilience technique adopted in JPEG2000 is based on the insertion of marker codes in the codestream. It does not provide enough error protection for critical data (such as the header and data in upper layers) in a high-error-rate channel. Therefore, we also propose a new method to combat channel errors. The method exploits the layer structure of the JPEG2000 codestream. Prior to transmission, data in the top layer is duplicated and protected by a chosen forward error correction (FEC) code. This data is then embedded into the bottom layer. In the receiver, a post-transmission process is applied to the codestream that extracts the embedded data for error recovery purposes. Our method provides multilevel error protection for the top layer and preserves the same codestream structure as the one in the JPEG2000 standard. In addition, the proposed scheme can be combined with the existing error resilience technique. |
