What is RF?
Radio frequency (RF) is the range of electromagnetic frequencies above the audio range and below infrared light (from 10kHz to 300GHz).

What is DTV?
DTV (digital TV) is a telecommunication system for broadcasting and receiving moving pictures and sound by means of digital signals, in contrast to analog signals used by traditional TV. DTV uses digital modulation data, which is digitally compressed and requires decoding by a specially designed TV set, or a standard receiver with an STB, or a PC fitted with a television card. The major DTV standards are ATSC (North America), DVB (Europe) and ISDB (Japan). All three use MPEG-2 video compression and Dolby Digital audio compression.
