Interconnectivity in the DTV Era: The Emergence of SDTI

Serial Data Transport Interface (SDTI) is emerging as the standard for transporting packetized audio, video, and data between cameras, VTRs, editing/compositing systems, video servers, and transmitters in professional and broadcast video environments. SDTI builds on the familiar SDI standard that is now widely used in studios and production centers to transfer uncompressed digital video between video devices. SDTI saves time and maximizes video quality. It provides for faster-than-realtime video transfers and a reduction in the number of decompression/ compression generations required during the video production process, while utilizing existing SDI infrastructure. Silicon and board-level adapters are starting to become available to allow manufacturers to build cost-effective, computer-based systems implementing SDTI. — This paper provides an overview of the SDTI (SMPTE 305M) specification. It also describes SDTI implementation issues related to computer-based equipment design, operating systems, and application software. The DV format, PCI-bus computer system architecture, Windows NT operating system, and editing application software are used as specific examples.
