Content and Metadata Workflow for User Generated Content in Live Production
2016
User generated content (UGC) can complement professional content for the coverage of live events such as concerts or sports events. Live streaming of UGC from mobile devices has recently gained popularity, but most solutions aim at providing the streams "as is", lacking the necessary environment to integrate UGC streams in a professional production. This requires taking care of synchronisation and of the quality of the incoming content. We propose a system for capturing live audio and video streams on a mobile device, performing automatic metadata extraction in real-time and indexing the metadata for access by a production system. The extracted metadata can be used to automate the selection of streams for use in the production. We also present the approach to sychronisation and provide evaluation results. Finally we describe the interfaces to professional IP-based production systems, considering recent standardisation efforts such as NMOS.
