NCL, standard declarative language of the Brazilian Terrestrial Digital TV System and ITU-T Recommendation for IPTV Services, provides a high level of reuse in the design of hypermedia applications. Not only static code reuse is possible, speeding up the application design time and minimizing the probability of programming errors by reusing already tested code spans, but also the reuse of code spans in execution, making easier the application understanding and the definition of relationships among application's components. Moreover, NCL allows not only the reuse inside the same application, but also the reuse among applications, besides the reuse of code spans stored in libraries external to the application. This paper discusses all the features provided by the language and implicitly proposes a methodology to take profit of these features.
