摘要:Interactive TV technology has been addressed in many
previous works, but there is sparse research on the
topic of interactive content broadcasting and how to
support the production process. In this article, the interactive
broadcasting process is broadly defined to include
studio technology and digital TV applications
at consumer set-top boxes. In particular, augmented
reality studio technology employs smart-projectors as
light sources and blends real scenes with interactive
computer graphics that are controlled at end-user terminals.
Moreover, TV producer-friendly multimedia
authoring tools empower the development of novel TV
formats. Finally, the support for user-contributed content
raises the potential to revolutionize the hierarchical
TV production process, by introducing the viewer
as part of content delivery chain.
