	abstract = {In this paper, we describe the conversion of {NCL} to Smix and discuss its main implications. {NCL} is a declarative language for the specification of interactive multimedia presentations which was adopted by the {ITU}-T H.761 recommendation for interoperable {IPTV} services. Smix is an {NCL}-like, domain-specific language with a similar purpose, but with a much simpler and more precise semantics. By implementing {NCL} over Smix, we bring to the former the notions of reaction and execution instants, and with them some benefits. From a practical perspective, we fix the semantics of the converted documents, get a leaner {NCL} player (the Smix interpreter), and simplify further conversions and interpretations. From a systems-design perspective, the structured conversion of {NCL} to Smix helps us tame the complexity of mapping the user-oriented constructs of {NCL} into the machine-oriented primitives and operations that realize them as a multimedia application. In the paper, we present both {NCL} and Smix, discuss related work on document conversion, and detail the proposed conversion process together with its prototype implementation.},
