In modern multimedia applications, scalability is a key functionality that allows transmission and representation of content in a wide variety of networks and terminals. In order to obtain full advantage of scalability features, techniques for detailed description and transformation of multimedia contents are needed. In this paper, the Bitstream Syntax Description Language is used for describing the structure of an MPEG-4 wavelet-coded texture. An XML-based bitstream description transformation is then applied for selecting some texture regions at an appropriate quality, effectively scaling down the processing and bandwidth requirements for view-dependent texture transmission. Appropriately applying this technique to 3D streaming guarantees quality-of-service, i.e. it certifies the best quality at limited network/processing resources.
