Digital TV and Distance Learning: Potentials and Limitations

One of the goals of the Brazilian Digital TV (DTV) system is to offer high-quality distance learning programs through DTV (t-learning). There are several differences between t-learning and e-learning that makes prohibitive just translate e-learning software's to DTV. This paper presents the potentials that t-learning programs can achieve on countries with high digital divide, and also the limitations of t-learning environment. Different scenarios of DTV resource availability are also presented and its influence on t-learning potentials. With these scenarios we present some t-learning applications that were developed, among with an authoring tool for these applications. These studies are being conducted considering the previous experiences on Web-based learning programs.
