Integration Model for Location-Based Services in iDTV Applications

摘要

The new Digital TV (DTV) standards offer not only a significant improvement in picture and sound quality but also create the ability to run applications sent over broadcast direct to the consumers. Additionally, DTV can be watched from mobile devices, which creates a new comprehensive niche for large scale applications based on location services. This paper proposes an architectural model for integration of Location Based Services (LBS) and interactive DTV applications running on mobile devices. In particular, this work extends the middleware Ginga giving him the ability to support interactive applications based on location trough a integration layers using OpenLS to make the communication of a context server and the Ginga application. The architecture has been evaluated using real scenarios and the analysis shows promissing results.
