STB – Set Top Box
The STB is an integral part of cable based TV services. Located at the customer premises, the device is responsible for demodulating, decrypting and processing MPEG-2 or MPEG-4 based TV content, in addition to providing the capability for the user to utilize interactive services. Newer IPTV systems use the same terminology, although in this case the term STB is being phased out in favour of the Home Gateway.
