BBC R&D reveals results of IP Studio trials
Work validates various elements of IP broadcast approach; further work suggested
BBC Research & Development has published a white paper detailing the findings of its IP Studio production trials at the Glasgow 2014 Commonwealth Games.
The report validates many aspects of the IP broadcasting approach taken including: Timing and Synchronisation; working with multiple formats; and using a Software Defined Infrastructure.
It also points to further work that is required in the areas of standardisation, industry collaboration and documentation.
Additional production trials are also suggested, in particular to examine how IP Studio could work for other genres other than sport.
The document reports: “Undertaking further production testing is crucial to improving our understanding of the opportunities and challenges associated with a future IP broadcast system. The department is particularly interested in using IP Studio technology to efficiently produce a wider range of programme genres and formats, for delivery to a diverse range of platforms.”
The opportunities for remote production were also highlighted.

BBC Research & Development’s IP Studio project was set-up to investigate the use of an IP-based infrastructure for live broadcasting. It is using a combination of theoretical design and experimental prototyping. During the Glasgow 2014 Commonwealth Games, IP Studio technology was used to produce a live ‘IP-end-to-end’ outside broadcast.
Using network connectivity provided by Virgin Media, JANET and the BBC, live Ultra HD video was captured from cameras in several competition venues, and delivered into a software-defined production system.
Programme output was delivered over IP using MPEG-DASH, and also broadcast from selected existing digital terrestrial television (DTT) transmitter locations using HEVC compression over DVB-T2.
