Media Production, Delivery and Interaction for Platform Independent Systems

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.

The consumption of audio-visual media has changed rapidly in the past decade. Content is now viewed on a variety of screens ranging from cinema to mobile devices. Even on mobile devices, today's user expects to be able to watch a personal view of a live event, for example, with a level of interactivity similar to that of typical web applications. On the other hand, current video and media production technology has not kept up with these significant changes. If we consider the complete media processing chain, the production of media, the delivery of audio-visual information via different kinds of distribution channels and the display and interaction at the end user's terminal, many challenges have to be addressed. The major challenges are the following.

Due to reuse of video content for different distribution channels, there is a need for conversion and post-production of the content in order to cope with different screen sizes. It is widely accepted that a movie production for cinema is recorded in a significantly different way to that intended for smaller screens. However, production budgets are limited; hence complex and costly re-purposing must be avoided. A good example is the production of 3D movies, where the aim is to develop camera technologies that allow 2D and 3D capture at the same time. Approaches to multiformat production that require parallel shooting or significant manual re-editing are no longer financially viable.

The convergence of broadcast and Internet requires future media production approaches to embrace the changes brought by web-based media . The habits of media consumption have changed drastically, partially due to the availability of user interaction with users freely navigating around web pages and interactively exploring maps and views of the street for example. Hence, future media production and delivery must support interactivity.

Although the overall bandwidth available for media delivery is continuing to increase, future media services will still face limitations, particularly if the end user at home or on-the-go is considered. Hence, new distribution formats are required to allow for the provision of audio-visual media beyond current HDTV formats , to support interactivity by the end user and to support intelligent proxies in the network that are capable of performing processing, which cannot be offered by low capacity devices. First developments towards resolution beyond HD are already appearing commercially, such as 4K camera and display technologies.

In addition, the user wants to decide when, where and on which device to watch audio-visual media as nowadays a variety of devices are available (including mobiles, TV at home and immersive large projection systems in cinemas). All of these devices must be supported by media delivery and rendering. Therefore, a large variety of audio-visual formats must be provided for the full spectrum of terminals and devices taking their special capabilities and limitations into account.

Even in live events, a lot of human operators such as dire
