After this, the author describes in detail on how to use existing open-source media player platform with interactive features to build a foundation of digital television services Interactive Player, which through real-time display of information from the implementation of interactive information and analysis from interactive experience of information TS data packets.In the final of this paper, the author provide the detailed test data of the function in the project implemented by the TS stream of private mutual information analysis module, show that the module is fully met the design requirements. Meanwhile, the interaction of the project has achieved the overall player test results were recorded. The interactive player that has been achieved in this project can already provide complete digital television services in the client PC machine.
