Java implementation of DTV services on the Android platform

摘要

This paper gives an overview of both specification and implementation details for integration of DTV services into the Android OS, using Java programming language. Since Java programming language is the language of choice for application development in the Android OS, we have proposed and implemented DTV services in this programming language. Java cannot be used to implement the entire DTV services functionality, so the native library has been developed to implement performance critical parts. The proposed Java API offers Java developers a wrapper around the native implementation, which encapsulates all relevant data structures and functions regarding DTV content manipulation. We have demonstrated our proposal on four key elements of DTV services: channel list, EPG, teletext, and subtitles.
