Context and overall objectives
Technological advances in UHD broadcasting and mobile social sharing leading up to the start of COGNITUS, coupled with over fifty years of research and development in multimedia systems technology, motivated research into how user-sourced media could enrich the conventional broadcasting experience.
The three year COGNITUS project brought together experts in video broadcasting, processing and analytics, with the aim of enhancing conventional ultra high definition (UHD) broadcasts by combining it with quality user generated content (UGC). COGNITUS offers an end-to-end platform to aggregate User Generated Content (UGC) during events, enhance to Ultra-High Definition (UHD) quality and provide semantic enrichment to facilitate the smooth integration in broadcast productions. COGNITUS includes innovative tools for the producers to manage calls for UGC contributions and access the enhanced content using a number of smart search methods, including via text, visual similarities and audio correlation. A suite of applications integrating innovative technological modules provide the overall functionality: a mobile app for UGC contributors; plot authoring for producers; a set top box and companion app for end-users; and a system administration application.
The COGNITUS platform was developed in response to an era of multimedia capture and consumption trends: (i) the general public progressively capturing more multimedia content via mobile phones, and sharing via social media platforms; (ii) changing media consumption by audiences, with increasing demand for superior picture quality evidenced by the increasingly wide availability of UHD TVs, High Dynamic Range (HDR) TVs and new display technologies. While these trends presented opportunities to provide new engaging experiences to audiences, COGNITUS identified a number of significant gaps in bridging the necessary technologies. Notably, a lack in variety of good quality UHD content existed at the outset of COGNITUS (partly due to very high production costs). Furthermore, available UGC media was typically poor technical and editorial quality. Any existing market solutions for exploitation of crowd-sourced multimedia content (e.g. from social media platforms) lacked reliable quality control and enhancement mechanisms, which COGNITUS technical innovations stepped in to address.
COGNITUS offers solutions to facilitate the convergence of broadcast and UGC for future interactive UHD services. The project outcomes provide proof of concept to cement the viability of interactive UHD content production and UGC exploitation, through use case demonstrators at large events. The demonstrators were based on two use cases drawn from real-life events, providing examples of the fascinating and potentially unlimited new services that could be unleashed by the confluence of UHD broadcasting technology and smart social mobile UGC brought by COGNITUS.
The COGNITUS project was realized into a robust platform and suite of applications, able to address the vision: to create a vibrant community for contributing UGC and provide high fidelity professional productions based on UGC content. COGNITUS facilitates reductions in the cost of producing high quality UHD content, by leveraging enhanced crowd-sourced content. Furthermore, the COGNITUS platform offers a means of engagement for the general public to get involved in broadcast content production, further enhancing their creativity, providing an immense sense of achievement through active participation rather than passive viewing.
