Error sensitivity of JPEG2000 codestream for efficient data protection on unreliable networks

Lossy compressed data, and multimedia content by extension can afford some further losses or degradation in lossy networks without removing its meaning. Still images coded by JPEG2000 exhibit a codestream hierarchically built with codeblock contributions organized in packets across quality layers and resolutions. In this paper we show how the image suffers from missing contributions in accordance with information available in packet header, with the layer inclusion tag especially. Our goal is to determine the level of importance of JPEG2000 packets with the only knowledge of the headers for efficient data protection on unreliable network.
