1. Set-top box

A set-top box, often abbreviated as STB, is an electronic device that receives and decodes television signals, typically from cable, satellite, or terrestrial sources, and converts them into video and audio output that can be displayed on a television set. Modern set-top boxes have evolved to offer a plethora of features beyond basic television viewing, including high-definition video, interactive services, streaming capabilities, and access to a wide array of digital content. These devices play a crucial role in the digital transition.
