With HbbTV 2, broadcasters are able to provide their viewers synchronised media content on companion devices. Use cases are for example second camera perspectives of a sports event or sign language speakers for hearing impaired people.
To investigate these and other use cases and to demonstrate a technical solution for this new feature, we decided to work on this topic within a master thesis. One of the outcomes was an Android application using the ExoPlayer to synchronise with an HbbTV Terminal, running the Inaris HbbTV Solution.
