HbbTV (Hybrid broadcast broadband TV) is an emerging force in the entertainment industry, and proper standarisation of technologies would be hugely beneficial for the creation of content. HbbTV aims to realise this vision and has been widely successful thus far. This paper introduces the MPAT (Multi Platform Application Toolkit) project, which is the result of multiple organisational entities effort and dedication to extend the capabilities and functionality of HbbTV, in order to ease the design and creation of interactive TV applications.

The paper also showcases the versatility of MPAT, by describing a series of case studies which provide digital storytelling and visual authoring of interactive applications which transcend traditional TV use cases, and instead provide a gripping interactive experience via integration with public displays.
