The hertz ( symbol : Hz ) is the derived unit of frequency in the International System of Units ( SI ) and is defined as one cycle per second . It is named after Heinrich Rudolf Hertz , the first person to provide conclusive proof of the existence of electromagnetic waves . Hertz are commonly expressed in multiples : kilohertz ( 103 Hz , kHz ) , megahertz ( 106 Hz , MHz ) , gigahertz ( 109 Hz , GHz ) , terahertz ( 1012 Hz , THz ) , petahertz ( 1015 Hz , PHz ) , exahertz ( 1018 Hz , EHz ) , and zettahertz ( 1021 Hz , ZHz ) . Some of the unit 's most common uses are in the description of sine waves and musical tones , particularly those used in radio- and audio-related applications . It is also used to describe the clock speeds at which computers and other electronics are driven . The units are sometimes also used as a representation of energy , via the photon energy equation ( E=hν ) , with one hertz equivalent to h joules .
DVB-T2 is an abbreviation for Digital Video Broadcasting - Second Generation Terrestrial ; it is the extension of the television standard DVB-T , issued by the consortium DVB , devised for the broadcast transmission of digital terrestrial television . DVB has been standardized by ETSI . This system transmits compressed digital audio , video , and other data in physical layer pipes ( PLPs ) , using OFDM modulation with concatenated channel coding and interleaving . The higher offered bit rate , with respect to its predecessor DVB-T , makes it a system suited for carrying HDTV signals on the terrestrial TV channel ( though many broadcasters still use plain DVB-T for this purpose ) . As of 2019 [ update ] , it was implemented in broadcasts in the United Kingdom ( Freeview HD , eight channels across two multiplexes , plus an extra multiplex in Northern Ireland carrying three SD channels ) , Italy ( Europa 7 HD , twelve channels ) , Finland ( 21 channels , five in HD ) , Germany ( six HD ( 1080p50 ) channels , with 40 in planning ) , the Netherlands ( Digitenne , 30 HD ( 1080p50 ) channels ) , Sweden ( five channels ) , Thailand ( 41 SD , 9 HD channels ) Flanders ( 18 SD Channels ) , Serbia ( eight channels ) , Ukraine ( 32 SD and HD channels in four nationwide multiplexes ) , Croatia ( two pay-TV multiplexes , one experimental multiplex to be used for regular TV broadcasting in HEVC and 1080p50 once legacy DVB-T transmissions cease ) , Denmark ( two pay-TV multiplexes with 20 channels ) , Romania ( 8 SD channels , 1 HD channel ) and some other countries .
