At this time, the processing method of data transmitted / received is adopted based on digital video broadcasting (DVB) which is a European digital television broadcasting standard, and the digital video broadcasting (DVB) standard, which is collectively known as the European method, is a cable television, satellite, terrestrial and public broadcasting antenna. It is characterized by improving the commonality of various media such as (SMATV), especially terrestrial (DVB-T) which is a terrestrial digital television broadcasting.
