TQTVD presents AstroTV version with support to the new JavaDTV APIs
In January 19th, during the Brazilian Digital TV Forum, TQTVD presented a news application based on the JavaDTV APIs. The interactivity was transmitted over the air in Sao Paulo.
Developed in Java and NCL, the interactive application allowed that the participants of the event could navigate through the articles with text and pictures. During the demonstration, the application warned the spectator every time a headline was sent by the broadcaster.
This was the second time that TQTVD did a presentation of AstroTV with Java support. The new middleware version is in agreement with JavaDTV, the new open source specification for Brazilian Digital TV, which is product of the partnership between Sun Microsystems and the Brazilian Terrestrial Digital TV Forum.
The middleware AstroTV is the commercial implementation that makes viable the usage of Ginga interactivity standard in Brazilian Digital TV. AstroTV is able to execute interactive applications developed in Java, NCL or LUA languages.
