The introduction of digital terrestrial television (DTT) brings multiple advantages. On the one hand, there are those advantages that allow optimizing the use of the radioelectric spectrum, such as: (i) the possibility of transmitting in adjacent channels, (ii) transmission of multiple contents through the same radio channel, and (iii) the use of single frequency networks (SFN). On the other hand, another advantage, not fully exploited, is to offer interactive content and value-added services, such as: learning (T-Learnning), voting (T-Voting), commerce (T-Commerce), etc. In ISDB-Tb interactivity, it is possible to use the GINGA middleware, developed in Brazil. In Ecuador, ISDB-Tb was adopted as a DTT standard in 2010. Nowadays, and despite having passed several years, the implementation of ISDB-Tb in Ecuador is still in its early stages. Therefore, none of its most important features has yet been exploited. This article presents the design of an interactive application that allows products to be commercialized through DTT. The application design was developed in Ginga-J to allow security options. In addition, the company's database was developed in MySQL with an APACHE server. The application allows the user to pay by credit card or by PAYPAL. The use of digital certificates and signatures was included to encode the information, protect the data and verify the identity of both parties, making the purchase a safe process. The use of digital signatures prevents the company from storing user financial data or the company making a fraudulent transaction, and vice versa. Through user acceptance tests (UAT), it was determined that the application is useful, the content is organized and understandable, and its handling is like making a purchase online. Finally, the purchase is verified with the discount in the balance of the user's account.

Keywords : Digital terrestrial television; Ginga-J; interactivity; ISDB-Tb; digital signature.
