BBC Prosperity Partnership: Future Personalised Object-Based Media Experiences Delivered at Scale Anywhere

个性化的媒体体验对于年轻人和老年人的受众参与至关重要，允许根据他们的兴趣定制更有意义的遭遇，使他们成为故事的一部分，并增加可访问性。BBC繁荣合作伙伴关系的目标是实现向未来个性化内容创作和大规模交付的转变，为家庭或移动中的公众提供服务。大众媒体视听“广播”内容（新闻、体育、音乐、戏剧）的演变已经越来越多地转向互联网交付，这为大规模向大众受众交付超个性化媒体体验创造了令人兴奋的潜力。这种全新的以用户为中心的媒体创作和传播方式，通过直接吸引个人体验的中心，而不是像现有的媒体格式（广播、电视、电影）那样预先定义内容，有可能颠覆媒体格局。这将允许一种以用户为中心的新形式的媒体体验，它可以动态地适应个人、他们的位置、媒体内容和制作人讲故事的意图，以及可用于呈现内容的平台/设备和网络/计算资源。BBC繁荣合作伙伴关系将把BBC置于这场“个性化媒体”革命的前沿，使其能够创造和提供新的服务，并将英国创意产业定位为引领未来个性化媒体创作和智能网络分发，为每个人提供个性化体验。大规模实现个性化体验提出了三个基本的研究挑战：捕获基于对象的内容表示，以便在渲染点动态适应个性化；生产以创造个性化的体验，提高每个用户的感知体验质量；通过智能地利用可用的网络、边缘和设备资源，为大众受众提供大规模的交付。BBC繁荣伙伴关系将解决主要的技术和创造性挑战，以大规模提供以用户为中心的个性化观众体验。用于捕获内容的机器理解的视听人工智能的进步将使捕获的2D视频流自动转换为基于对象的媒体（OBM）表示。OBM将允许适应高效的生产、交付和个性化的媒体体验，同时保持捕获视频内容的感知质量。为了向数百万受众提供个性化体验，需要将媒体处理和分发架构转变为混合和分布式低延迟计算平台，从而允许跨网络灵活部署计算密集型任务。这将在成本和能源使用方面实现效率，同时在系统的技术限制下为观众提供最佳质量的体验。

Personalisation of media experiences for the individual is vital for audience engagement of young and old, allowing more meaningful encounters tailored to their interest, making them part of the story, and increasing accessibility. The goal of the BBC Prosperity Partnership is to realise a transformation to future personalised content creation and delivery at scale for the public at home or on the move.Evolution of mass-media audio-visual 'broadcast' content (news, sports, music, drama) has moved increasingly towards Internet delivery, which creates exciting potential for hyper-personalised media experiences delivered at scale to mass audiences. This radical new user-centred approach to media creation and delivery has the potential to disrupt the media landscape by directly engaging individuals at the centre of their experience, rather than predefining the content as with existing media formats (radio, TV, film). This will allow a new form of user-centred media experience which dynamically adapts to the individual, their location, the media content and producer storytelling intent, together with the platform/device and the network/compute resources available for rendering the content.The BBC Prosperity Partnership will position the BBC at the forefront of this 'Personalised Media' revolution enabling the creation and delivery of new services, and positioning the UK creative industry to lead future personalised media creation and intelligent network distribution to render personalised experiences for everyone anywhere.Realisation of personalised experiences at scale presents three fundamental research challenges: capture of object-based representations of the content to enable dynamic adaption for personalisation at the point of rendering; production to create personalised experiences which enhance the perceived quality of experience for each user; and delivery at scale with intelligent utilisation of the available network, edge and device resources for mass audiences. The BBC Prosperity Partnership will address the major technical and creative challenges to delivering user-centred personalised audience experiences at scale. Advances in audio-visual AI for machine understanding of captured content will enable the automatic transformation of captured 2D video streams to an object-based media (OBM) representation. OBM will allow adaptation for efficient production, delivery and personalisation of the media experience whilst maintaining the perceived quality of the captured video content. To deliver personalised experiences to audiences of millions requires transformation of media processing and distribution architectures into a hybrid and distributed low-latency computation platform, allowing flexible deployment of compute-intensive tasks across the network. This will achieve efficiency in terms of cost and energy use, while providing optimal quality of experience for the audience within the technical constraints of the system.
