Retransmission strategies for optimized JPEG 2000 image transmission in wireless environment
Transmission of images and video over lossy packet networks is known to pose severe technical challenges; FEC and ARQ are often used to make the transmission more robust towards potential data losses. In this paper we investigate ARQ strategies aimed at optimizing the transmission of progressive codestreams over wireless environments characterized by packet losses. The analysis is specifically tailored to the JPEG 2000 family of standards, and considers Part 1 and 3 for image and video compression, and Part 11 for additional error protection tools. We show that ad-hoc retransmission strategies significantly outperform basic ARQ schemes, providing improved end-to-end image and video quality.
