SDTI stands for Serial Digital Transport Interface, a standard protocol used in the broadcasting industry for transmitting uncompressed digital video and audio signals over a variety of media. It was first introduced by the Society of Motion Picture and Television Engineers (SMPTE) as a means to enhance the quality and efficiency of signal transmission in professional video production and distribution.
SDTI is designed to carry video and audio signals in a serial manner at high data rates, allowing for the seamless transfer of uncompressed digital content between various devices within a broadcast workflow. It provides a reliable and consistent transfer of data, ensuring that video and audio content remains intact without any loss or degradation.
The protocol uses a synchronous serial interface to transport the data, typically utilizing coaxial or fiber optic cables for transmission. It supports various video formats, including standard definition (SD), high definition (HD), and even ultra-high definition (UHD) resolutions.
SDTI also facilitates the exchange of metadata, allowing for efficient synchronization and control of different broadcast equipment. This enables seamless interoperability between different devices, such as cameras, switchers, routers, servers, and monitors, within a production or broadcasting environment.
Overall, SDTI helps streamline the transmission and distribution of digital video and audio signals in the broadcasting industry, ensuring high-quality content delivery and efficient workflow management.
