In the multiple description paradigm, a controllable amount of redundancy is inserted among descriptions, in order to help estimating those ones which are possibly lost due to network congestion. This redundancy can also be exploited in order to correct errors at bit level. In this paper, we propose a novel technique to generate multiple descriptions of video encoded with motion-JPEG 2000, which exploits the inserted extra redundancy also to guarantee error protection in case all descriptions are received, but are possibly affected by bit errors. This method yields excellent performance, since it guarantees not only protection of video information transmitted over non prioritized networks subject to independent packet erasure processes, but also resilience towards the corruption at bit level. Moreover, the generated streams are fully compatible with the part 3 of the JPEG 2000 standard.
