DVB-T2
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). , 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), ...

DVB-T
DVB-T, short for Digital Video Broadcasting – Terrestrial, is the DVB European-based consortium standard for the broadcast transmission of digital terrestrial television that was first published in 1997 and first broadcast in Singapore in February, 1998. This system transmits compressed digital audio, digital video and other data in an MPEG transport stream, using coded orthogonal frequency-division multiplexing (COFDM or OFDM) modulation. It is also the format widely used worldwide (including North America) for Electronic News Gathering for transmission of video and audio from a mobile newsgathering vehicle to a central receive point. It is also used in the US by Amateur television operators. Basics Rather than carrying one data carrier on a single radio frequency (RF) channel, COFDM works by splitting the digital data stream into a large number of slower digital streams, each of which digitally modulates a set of closely spaced adjacent sub-carrier frequencies.

ITV1
ITV1 (formerly known as ITV) is a British free-to-air public broadcast television channel owned and operated by the British media company ITV plc. It provides the Channel 3 public broadcast service across all of the United Kingdom except for the central and northern areas of Scotland where STV provides the service. ITV1 as a consistent national channel (with dedicated slots for regional news and other regional programmes) evolved out of the old ITV network – a federation of separately owned regional companies which had significantly different local schedules and branding. During the 1990s, the differences between the schedules in each region gradually reduced – partly through the consolidation of ownership and partly through the standardisation in the volume and scheduling of regional programmes. In 2002, a major change of appearance occurred when all ITV regions in England adopted national continuity. Regional logos vanished and regional names were mentioned only before ...
