What is DVB-T2? DVB-T2 is the world’s most advanced digital terrestrial television (DTT) system, offering more robustness, flexibility and at least 50% more efficiency than any other DTT system. It supports SD, HD, mobile TV, or any combination thereof.

DVB-T is an abbreviation for Digital Video Brodcasting Terrestrial
DVB-T is a technical standard, developed by the DVB Project, that specifies the framing structure, channel coding and modulation for digital terrestrial television (DTT) broadcasting. The first version of the standard was published in March 1997 and in the twelve years since then it has become the most widely adopted DTT system in the world. It is a flexible system that allows networks to be designed for the delivery of a wide range of services, from HDTV to multichannel SDTV, fixed, portable, mobile, and even handheld reception. The DVB Project has now created a next generation terrestrial specification, DVB-T2, designed to meet the needs of countries after they have completed Analogue Switch-Off (ASO).
DVB-H is a technical specification for the transmission of digital TV to handheld receivers such as mobile telephones and PDAs. Published as a formal standard (EN 203 204) by ETSI in November 2004, it is a physical layer specification designed to enable the efficient delivery of IP-encapsulated data over terrestrial networks. The creation of DVB-H, which is closely related to DVB-T, also entailed modifications of some other DVB standards dealing with data broadcasting, Service Information, etc. It can be used as a bearer in conjunction with the DVB-IPDC systems layer specifications or alternatively with the OMA BCAST specifications. A non-proprietary open standard, DVB-H has broad support across the industry and services are now on air in more than ten countries.
Until now the Eureka 147 DAB digital radio standard has always been broadcast using MPEG 1 audio layer II encoding. Since the original introduction of the Eureka 147 digital radio broadcasting standard (commonly referred today as ("Classic DAB"), more efficient coding schemes and algorithms have emerged.
