Anotation

ISO/IEC 15444-11:2007 provides a syntax that allows JPEG 2000 coded image data to be protected for transmission over wireless channels and networks. Protection services include error detection and correction capability for header and bitstream, description of the error sensitivity of different portions of the compressed data, and description of possible residual errors in the compressed data. The syntax allows these protection services to be applied to coded image data in part or in their entirety. These services are designed so as to maintain the inherent features of JPEG 2000, such as scalability and access to various spatial areas, resolution levels, colour components and quality layers, while providing protection services on these elements. LISO/CEI 15444-11:2007 a pour but de definir une syntaxe qui permette de proteger les donnees dimages codees a transmettre via les canaux et reseaux hertziens. Les services de protection font appel a plusieurs moyens: capacite de detection et de correction des erreurs dans les en-tetes et dans les flux binaires, description de la sensibilite aux erreurs de telle ou telle portion des donnees comprimees, et description des erreurs residuelles possibles dans les donnees comprimees. La syntaxe permet dappliquer ces services de protection a une partie ou a lintegralite des donnees dimage codees. Ces services sont concus pour conserver les proprietes intrinseques du systeme JPEG 2000, telles que la capacite devolution et lacces a diverses zones spatiales, les niveaux de resolution, les composantes couleurs et les couches de qualite, tout en assurant des services de protection pour ces elements.
