STB (Set-Top Box) is a device that connects a regular TV to digital television services, satellite signals, or streaming content. Think of it like a translator that takes complex TV signals and makes them viewable on your television. Cable boxes from companies like Comcast or satellite receivers from DirecTV are common examples of STBs. In the broadcasting industry, professionals work on designing, testing, and maintaining these boxes to ensure viewers can watch their favorite shows and access interactive features like program guides and on-demand content.
