Abstract:
This paper presents a scalable and dynamic scheme for robust JPEG 2000 images/video transmission over wireless channels. The proposed system relies on an adaptive bandwidth estimation tool to select the suitable JPEG 2000 streams, layers and resolution. A Wireless JPEG 2000 (JPWL) compliant Forward Error Correction (FEC) scheme is introduced. An optimal layer oriented Unequal Error Protection Forward Error Correction rate allocation scheme is proposed to ensure codestreams protection against transmission errors. The main advantages of the proposed scheme are its optimality, its compliance to Wireless JPEG 2000 (the 11th part of JPEG 2000 standard) and its low time consumption. We demonstrate that our proposed scheme outperforms the layer oriented FEC scheme proposed by Guo et al. and other existing layer based FEC schemes. We also show that, due to its low run time, our layer based scheme is a good candidate for highly time constrained motion JPEG 2000 video streaming applications, thus, in this sense, its overcomes the limitation of optimal packet oriented FEC rate allocation scheme. We then validate the effectiveness of our proposed layer oriented scheme with a Wireless Motion JPEG 2000 client/server application.
