Content Metadata Exposure and Content Synchronization Task Force


This task force aims to

  • Investigate how to expose TV metadata to web applications
  • Investigate mapping between Media Element API and in- band metadata
  • Enable synchronization scenarios up to frame accurate

Our Approach

  • We will be gathering (and authoring) use cases related to TV Synchronisation and applications
  • We will derive requirements from our use cases. Some will be relevant to Metadata/Sync, others will be contributed to other task forces such as the Terminal TF
  • We do not expect to specify or choose any broadcast/content metadata format. Our requirements are likely to be limited to a bridge between the TV/broadcast system and the web stack, allowing discovery and access to this metadata through a standard API.
