چکیده

The rapid growth of wireless communication has resulted in a demand for robust transmission of compressed images over wireless channels. The challenge of robust transmission is to protect the compressed image data against loss, in such a way as to maximize the received image quality. The paper addresses this problem; investigating unequal error protection of JPEG2000 compressed imagery. More particularly, the results reported in this paper provide guidance concerning the selection of JPEG2000 coding parameters and appropriate combinations of RS (Reed-Solomon) codes, for typical wireless bit error rates in the range 10 to 10.

Backward-Compatible Interleaving Technique for Robust JPEG2000 Wireless Transmission

This paper presents a forward error correction technique that can be applied to protect JPEG2000 streams during their transmission over wireless channels with both sparse and packet error statistics. To this aim, we adopt the tools of the JPEG2000 Wireless (JPWL) standard, by introducing a method for Unequal Error Protection (UEP) and a virtual interleaving technique of the stream. All these te...

A New Unequal Error Protection Technique Based on the Mutual Information of the MPEG-4 Video Frames over Wireless Networks

The performance of video transmission over wireless channels is limited by the channel noise. Thus many error resilience tools have been incorporated into the MPEG-4 video compression method. In addition to these tools, the unequal error protection (UEP) technique has been proposed to protect the different parts in an MPEG-4 video packet with different channel coding rates based on the rate...

Jpeg 2000 Transmission over Wireless Channels Using Unequal Power Allocation

We address the issue of JPEG2000 transmission over wireless channels using Unequal Power Allocation (UPA). First, an algorithm for multicasting JPEG2000 images over MIMO systems is proposed. According to antenna selection orders requested by receivers, the channel assignment unit transmits the substreams with different powers from antennas. The decoder is modified such that when two copies of a...
