The term ‘object-based media’ has become commonly used to describe the representation of media content by a set of individual assets together with metadata describing their relationships and associations. At the point of consumption these objects can be assembled to create an overall user experience. The precise combination of objects can be flexible, and responsive to user, environmental and platform specific factors. An object-based approach like this can serve and users more effectively; by optimising the experience to best suit their access requirements, the characteristics of their playback platform or personal preferences.
This paper presents an overview of the key characteristics and potential benefits of Object-Based Broadcasting and a case study of an object-based audio documentary, which can change duration in response to implicit or explicit input from a listener. Further examples will be given to illustrate the capabilities of a future object-based broadcasting system.
