Traditional Forward Error Correction (FEC) rate allocation schemes, used to enhance the robustness of JPEG 2000 images and video against transmission errors, are based either on Packet oriented Unequal Error Protection or on Layer oriented Unequal Error Protection. As both approaches hold their advantages, unifying them under a new framework becomes a crucial issue. In this paper, we address this...
In this paper we address the problem of switching between packet-oriented and layer-oriented forward error correction (FEC) schemes for robust JPEG 2000 images and video transmission over wireless channels. Based on an analysis of the time consumption of a smart FEC scheme, we derive an optimal switching threshold for efficient JPEG 2000 codestreams protection. The derived optimal switching threshold...
A new fast forward error correction (FEC) allocation algorithm for unequal error protection (UEP) of video transmission over wireless channels is proposed in this paper. First, an UEP scheme, which takes into consideration the non-uniformly distributed importance of frames in a group of pictures (GOP) and macroblocks in a video frame, is proposed. An enhanced video error propagation model, namely...
