HbbTV 1.5 additions: One design, implementation and integration

This paper presents our work and experience in designing, implementing and integrating HbbTV 1.5 additions. We extended existing HbbTV software stack which provides functionalities required by HbbTV 1.1 standard. Key additions that HbbTV 1.5 standard brings are EIT schedule (full 7-day EPGs), HTTP adaptive streaming based on the MPEG DASH specification and DASH delivered content protection with DRM technologies. This paper focuses on the following two additions: EIT schedule and MPEG DASH. Third addition is not mandatory by the HbbTV 1.5 and is left for further work.
