Next Steps

Future of iTV is still uncertain

If application is to be used commercially, some tasks must still be done



We suggest that Web Service Interface should be further developed



Testing on real set-top-box
Fixing truncation of texts
Simplifying common queries
Fixing some mistakes in the interface documentation
Our parser classes can successfully be used in other applications also
