Abstract
This paper introduces a concept for file delivery using the features of scalable (or hierarchical) media like the Joint Photographic Experts Group 2000 (JPEG 2000) image coding system. The innovation of this concept is that, due to the scalability feature, the recipient may start to work with the transmitted content even before completion of the transfer. For this, a reduced subvariant, derived from the scalable sources, will be transmitted in the first phase until the full media data reaches its destination. The recipient is therefore able to get a preview faster. Subsequent phases will add more and more information to the subvariant transmitted in the first phase. A concept called the "Substitution Method" (which was presented at the SMPTE 2012 Annual Technical Conference) enables the software running at the destination to rebuild the file structure of each media file and to simulate missing data so that the images can be used for further processing before the overall transmission is completed.
