This presentation introduces a concept of a file delivery ecosystem, especially exploiting the features of scalable (or hierarchical) media like JPEG 2000. The innovation of this concept is the possibility that the recipient may start to work with the transmitted content even before completion of the transfer due to the scalability feature. For this, a reduced sub-variant, 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 sub-variant transmitted in the first phase. Due to a concept called Substitution Method - which has been presented at ATC 2012 - the software running at the destination is able 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.
