A satellite broadcasting receiver, commonly called a set top box (STB), is a device that connects to a TV set in a home or office to receive cable or satellite broadcasting in a home. By amplifying or removing noise, a viewer can send a video signal to a TV set according to a desired channel. Depending on whether your TV set is analog or digital, you will need to install a suitable STB.

These set-top boxes can be roughly classified into cable TV (hereinafter referred to as CATV), satellite broadcasting (ie, broadcast satellite (hereinafter referred to as BS), communication satellite (hereinafter referred to as CS)), digital terrestrial broadcast (hereinafter referred to as DVB), and the like. The basic system configuration is almost the same, but the CATV does not require an antenna, whereas the BS, CS or DVB requires a separate antenna. The two-way service can be easily supported for CATV, but for the BS, CS, and DVB, a separate line such as a telephone line is required to provide two-way service.

On the other hand, when an error occurs in the set-top box (STB) and requires re-installation, the error is corrected by using an RS-232C method or a set-top box method.
