As the performance and cost-effectiveness of packet-switched networks continue to increase, broadcasters can benefit from handling realtime production-quality video and audio as first-class citizens on Internet Protocol (IP) infrastructure. When combined with capturing richer production datasets, this provides new opportunities to produce innovative, and more personalized, products. BBC Research & Development is developing a framework to investigate going beyond traditional technologies such as serial digital interface (SDI) toward an IP-based infrastructure, using widely adopted networking protocols and techniques. The framework treats items of content, such as video frames, as well as data events generated in a production, as uniquely identified and time-stamped objects. For live working, these are multicast at high quality locally and published as web feeds for remote access; they are also stored for immediate use by downstream processes and devices, without the overheads associated with file-based transfers.
