Introduction. Media Production, Delivery and Interaction for Platform Independent Systems
If we consider the complete media processing chain, the production of media, the delivery of audiovisual information and the display and interaction at the end user's terminal, many challenges have to be addressed. The challenges are: (i) the need for conversion and post-production of the content in order to cope with different screen sizes; (ii) the need to embrace the changes brought by web-based media; (iii) the need to develop new distribution formats to allow for the provision of audiovisual media to support interactivity by the end user; (iv) the need to provide audio-visual formats for terminals and devices as per their capabilities and limitations; and (v) the need to develop automated viewpoint selection to reduce production costs. This chapter highlights some these challenges. A new concept appearing on the horizon that could provide answers to these issues and challenges is referred to as format-agnostic media production.
