CE on Metadata Adaptation – Integration of Multiple descriptions

In this document, a sub part of the CE on Adaptation Hint DS defined in document [4] is presented. Four partners are involved in this CE: Mitsubishi Electric Corp., Fujitsu, Denso Corporation and University of Brescia. While the first three are focusing in the use of AdaptationHint DS for the adaptation of a single DS (see document m8962), the objective of University of Brescia is to show how integration of multiple descriptions of a given content can be useful for the reduction of the number and dimension of metadata and DI. In this context the AdaptationHint DS has been tested to support the integration phase, concluding that it can be useful in order to speed up the process and to reduce the memory occupancy. Additional comment about metadata integration have been included in this report, considering also the use of two new adaptation tools. The first tool is related to the problem of to establish which is elementary unit that has to be used in the comparison of different description while the second aims to support the preferences of a user about metadata transcoding. In the following, an introduction to the metadata integration problem will be given in order to point out the problems related to it. For the same reason a use case is presented before the description of the experiment setup and results. At the end, final conclusions and remarks are included.
