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

个人媒体体验的个性化对于年轻人和老年人的受众参与度至关重要，允许根据他们的兴趣进行更多有意义的接触，使他们成为故事的一部分，并增加可访问性。BBC繁荣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，为家庭或移动的公众提供。大众媒体视听广播内容(新闻、体育、音乐、戏剧)的演变越来越转向互联网交付，这为大规模交付给大众的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交付方法有可能通过直接让处于其体验中心的个人参与来扰乱媒体格局，而不是按照现有的媒体格式(广播、电视、电影)预先定义内容。这将允许一种以用户为中心的新形式的媒体体验，它动态地适应个人、他们的位置、媒体内容和制片人的讲故事意图，以及可用于呈现内容的平台/设备和网络/计算资源。BBC繁荣伙伴关系将把BBC定位在这场能够创建和提供新服务的“个性化媒体”革命的前沿，并将英国创意产业定位为引领未来的个性化媒体创建和智能网络分发，以在任何地方为每个人提供个性化体验。规模化的个性化体验带来三个基本的研究挑战：捕获内容的基于对象的表示，以便能够在呈现点动态适应个性化；生产以创造个性化体验，提高每个用户的感知体验质量；以及通过智能利用可用网络、边缘和设备资源为大众提供规模化交付。BBC繁荣伙伴关系将解决大规模提供以用户为中心的个性化观众体验的主要技术和创意挑战。用于机器理解捕获内容的视听人工智能的进步将使捕获的2D视频流能够自动转换为基于对象的媒体(OBM)表示。OBM将允许对媒体体验的高效制作、交付和个性化进行调整，同时保持捕获的视频内容的感知质量。要为数以百万计的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分布式低延迟计算平台，从而允许在整个网络中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.
