The Society of Motion Picture and Television Engineers is a highly respected organization that works to establish technical frameworks for the creation and distribution of films and television programs. Although it is not the only group involved in broadcast standards, some of its good works involve such critical signal distribution standards as the Serial Digital Interface (SDI), ST 2022 and ST 2110.
SDI, first defined in 1989, remains a popular and reliable method of transporting high-quality video signals from point-to-point within a facility or field production. (The current version of SDI is “SMPTE ST 2083.”) However, since 1989, our world has become increasingly data-oriented and it soon became obvious that transporting broadcast-quality video signals over IP networks was both necessary and advantageous. SMPTE’s first standard to marry SDI video with IT was the ST 2022 standard.
