9.1 What is serial digital interface (SDI)?

This is the first video of a two-part series discussing Serial Digital Interface (SDI), which is used for video transmission in television stations, high-end video capture and storage applications. In this video, we'll teach you about the elements involved in the SDI signal path and the effects of its transmission media, 75-ohm coax. We'll also discuss its characteristics and explain how SDI data coding and framing helps improve the performance of SDI components.
