Flavor: A Formal Language for Audio-Visual Object Representation

摘要

We present Flavor, a formal language for audio-visual object representation, that has been developed to describe any coded multimedia data in formats such as GIF, JPEG and MPEG. The language comes with a translator for generating C++/Java code from the Flavor description, and the generated code can include bitstream reading, writing and tracing methods. Since Version 5.0, the translator has been enhanced to also support XML. With the enhanced translator, the generated C++/Java code can include a method for producing XML documents that correspond to the bit-streams described by Flavor. The description can also be used to generate a corresponding XML schema. Additionally, a software tool for converting XML representation of multimedia data back into bitstream form is provided.
