Abstract: 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.

bio
Toshiaki Kojima has worked in both the audio video (AV) and information technology (IT) worlds over the past 32 years. He joined Sony in 1982 after graduating from Waseda University, Japan. For the first 20 years of his career he was involved mainly in the design of professional videotape recorders, from 1 in. to the e-VTR. In 2004, he received a Sports Emmy statuette in recognition of the role of the e-VTR when NBC was awarded a Sports Emmy for coverage of the Athens Olympics. Following the e-VTR project, he moved into research and development (R&D) with the aim of replacing dedicated professional AV interfaces with those of general IP. This effort is ongoing. — Kojima is an active participant in various network-related industry and standardization bodies, including FIMS, the Video Services Forum (VSF), SMPTE and the Joint Task Force on Professional Networked Streamed Media (JT-NM). He holds 20 Japanese and international patents, and is a Massachusetts Institute of Technology Fellow.

John Stone has been general manager of Sony Broadcast & Professional Research Labs (BPRL) in the U.K. since 2002. The mission of BPRL is to provide innovation and new technology for the Sony B2B business in the areas of professional media and broadcast as well as other markets such as healthcare and security. Stone leads a strong team of engineers with expertise in activities ranging from feasibility study, algorithm development, system prototyping through to product and solution development. The current focus of the BPRL team is in the areas of 4K content creation, sport production, video codec, as well as IP networking for broadcast production.
Jian-Rong Chen
bio
Jian-Rong Chen is a principal engineer at Sony Broadcast & Professional Research Labs in the U.K. His technical background includes telecommunication and data network modeling and simulation, network management software, video over IP and software development. Chen was a member of a team within Sony BPRL that developed an SDI over IP routing system prototype, which demonstrated the technical feasibility of using IP network for live production in 2002. Before joining the broadcast industry, he worked in the telecommunication industry on ATM switches, and also on European Union sponsored research project ICM (Integrated Communication Management of Broadband Networks). He is a member of IEEE.
