A Methodology for Providing Encrypted-Content Decoding in DTV Play

Recently, the middleware Ginga, which was developed for the Brazilian digital television system (SBTVD), was updated. It is now called DTV Play and presents features related to the integrated broadcast-broadband paradigm, including execution of hypertext markup language version 5 (HTML5) applications and encrypted-content handling. However, such novelties require deeper integration with platforms, which already exists for native HTML5 engines. This work proposes a methodology for implementing those features through HTML5 engines, aiming at reducing development time and providing a simpler framework for SBTVD receivers. This approach is currently being implemented and has already proved its efficacy and efficiency.
