JPWL: JPEG 2000 for Wireless Applications

چکیده
In this paper, we present the current status of the JPWL standardization work item. JPWL is an extension of the JPEG 2000 baseline specification in order to enable the efficient transmission of JPEG 2000 codestream over an error-prone network. In particular, JPWL supports a set of tools and methods for error protection and correction such as Forward Error Correcting (FEC) codes, Unequal Error Protection (UEP), and data partitioning and interleaving. We then evaluate the performance of the JPWL Error Protection Block (EPB) tool. We consider two configurations of EPB: to protect the Main and Tile-part headers, or to protect the whole codestream using UEP. Experimental results show a significant quality improvement when using EPB compared to baseline JPEG 2000.

This paper presents a forward error correction technique that can be applied to protect JPEG2000 streams during their transmission over wireless channels with both sparse and packet error statistics. To this aim, we adopt the tools of the JPEG2000 Wireless (JPWL) standard, by introducing a method for Unequal Error Protection (UEP) and a virtual interleaving technique of the stream. All these te...

This paper presents an Unequal Power Allocation (UPA) strategy for the transmission of a JPEG 2000 Wireless (JPWL) image. To ensure the Quality of Service (QoS), we exploit the channel diversity with a Closed-Loop MIMO scheme. It relies on the Channel State Information (CSI) knowledge at the transmitter side that diagonalizes a MIMO channel into several hierarchical SISO subchannels. In the pro...
