A Practical Approach to IP Live Production

Toshiaki Kojima, John J. Stone, Jian-Rong Chen, Paul N. Gardiner

Serial digital interface (SDI) infrastructure has been a fundamental building block for video and audio communications within studios for many years. Meanwhile, the bandwidth of generic Internet Protocol (IP) networks has continued to increase along with falling costs, such that 10 Gbit/sec infrastructure is now commonly available. Exploiting this high-bandwidth commodity infrastructure, an IP network could be deployed in the studio to form an IP live production system. This paper explores the technical requirements, design considerations, and standards approaches for IP live production to be able to deliver business benefits compared to current SDI technology whilst retaining familiar SDI-based production practices. This paper also describes a sample implementation of an IP-based audio-video router showing how the discussed technologies can be applied to realize the same functionality as a conventional SDI router.
