Samsung Electronics announced that its Hybrid broadcast broadband TV (HbbTV) media player is available as an open source project named HbbPlayer on github . This will enable broadcasters and application developers who are writing HbbTV applications to test and validate them on a platform which can be implemented on any HbbTV 1.5-compliant TV.
