A Set-top-Box (STB) is a very common name heard in the consumer electronics market. It is a device that is attached to a Television for enhancing its functions or the quality of its functions. On the other side, the STB is connected to an external source of signal, like satellite, cable, terrestrial or internet. The STB processes the signal it receives and turns it into content, which is then displayed on the television screen or other display device.
There are different types of STBs based on what kind of signals it can receive and what kind of processing it can do. The most widely used STBs are DVB STBs, which receive DVB (Digital Video Broadcast) transmission. This digital TV broadcast can be any one of the three types – Satellite, Cable, or Terrestrial (DVB-S, DVB-C, or DVB-T). Another type of STB is IPTV STBs, which are used to bring broadband content, the data shared on the internet including multimedia, to Television. There are many other types of STBs based on different standards and geographies.
