This paper presents integration of the concept of Decisional DNA Digital TV with Smart TV. The integration provides the Digital TV viewer with smart assistance that helps to watch TV shows according to the viewer’s habit discovered through past viewing experience. Decisional DNA is a domainindependent, flexible, and standard experiential knowledge representation structure that allows its domains to acquire, reuse, evolve, and share knowledge in an easy and standard way. The presented approach demonstrates how the Decisional DNA-based systems can be integrated with Digital TV technique, and how it captures and reuses the TV viewer’s watching experience. Illustrative test of the suggested approach is presented in the paper with a set of experiments.
