||Examining the issues facing broadcasters using broadband distribution networks|
The core activity of SP-BBN is media delivery over the internet. This subject is crucial for EBU members, since broadband networks using IP as distribution means are growing in importance. Internet opens new possibilities delivering live and on demand services, but is still the most costly delivery medium when comparing cost per viewer with traditional broadcast techniques. Also there is no real Quality of Service that can be guaranteed when delivering audiovisual content over this best effort network. Content providers simply do not have control of the whole distribution chain. Therefore the BBN investigates how the best Quality of Experience can be reached for the audience and what technical / infrastructural conditions are needed to reach this situation.
The group concentrates on the backend of media deliverance over IP-networks, including delivery formats for adaptive streaming over HTTP like (MPEG DASH, HLS, ADS, Smooth Streaming) and delivery protocols like HTTP, UDP, RTMP, RTSP but also delivery techniques like P2P or CDNs.
The group aims to deliver practical information about technical research subjects by defining deliverables as recommendations for broadcast organisations and industry via standardisation bodies; feasibility studies for proofs of concept, demos or development of tools; the actual development of those PoCs, demos and tools.
HIGH LEVEL OBJECTIVES
• Monitor and inform Members on the topic of broadband networks and, if necessary, propose actions from the EBU in this domain.
• Facilitate exchange of knowledge and experiences between broadcasters
• Research on relevant topics
• Development of ‘proof of concepts’, demos and tools when necessary
• Preparation of the programme of the annual BroadThinking
• Monitor new developments in technologies and react (if necessary) by reporting to members and/or create work items in order to help members to cope with the new technologies/workflows.
