Abstract

This paper presents an error-resilient wavelet-based multiple description video coding scheme for the transmission of video over wireless channels. The proposed video coding scheme has been implemented and successfully tested over the wireless Iridium satellite communication network. As a test bed for the develope dcodec, we also present an inverse multiplexing unit that simultaneously combines several Iridium channels to form an effective higher-rate channel, where the total bandwidth is directly proportional to the number of channels combined. The developed unit can be integrated into a variety of systems such as ISR sensors, aircraft, vehicles, ships, and end user terminals (EUTs), or can operate as a standalone device. The recombination of the multi-channel unit with our proposed multi-channel video codec facilitates global and on-the-move video communications without reliance on any terrestrial or airborne infrastructure whatsoever.
