Presents current trends and potential future developments by
leading researchers in immersive media production, delivery,
rendering and interaction
The underlying audio and video processing technology that is
discussed in the book relates to areas such as 3D object
extraction, audio event detection; 3D sound rendering and face
detection, gesture analysis and tracking using video and depth
information. The book will give an insight into current trends and
developments of future media production, delivery and reproduction.
Consideration of the complete production, processing and
distribution chain will allow for a full picture to be presented to
the reader. Production developments covered will include integrated
workflows developed by researchers and industry practitioners as
well as capture of ultra-high resolution panoramic video and 3D
object based audio across a range of programme genres. Distribution
developments will include script based format agnostic network
delivery to a full range of devices from large scale public
panoramic displays with wavefield synthesis and ambisonic audio
reproduction to ‘small screen’ mobile devices. Key
developments at the consumer end of the chain apply to both passive
and interactive viewing modes and will incorporate user interfaces
such as gesture recognition and ‘second screen’ devices
to allow manipulation of the audio visual content.
* Presents current trends and potential future developments by
leading researchers in immersive media production, delivery,
rendering and interaction.
* Considers the complete production, processing and distribution
chain illustrating the dependencies and the relationship between
different components.
* Proposes that a format-agnostic approach to the production and
delivery of broadcast programmes will overcome the problems faced
with the steadily growing number of production and delivery
formats.
* Explains the fundamentals of media production in addition to
the complete production chain, beyond current-state-of-the-art
through to presenting novel approaches and technologies for future
media production.
* Focuses on the technologies that will allow for the realization
of an E2E media platform that supports flexible content
representations and interactivity for users.
An essential read for Researchers and developers of audio-visual
technology in industry and academia, such as engineers in broadcast
technology companies and students working toward a career in the
rapidly changing area of broadcast both from a production and an
engineering perspective.
