Excerpt: This is a list of digital television deployments by country, which summarises the process and progress of transition from analogue to digital broadcasting. The transition to digital television is a process that follows different paces around the world. Although digital satellite television is now commonplace, the switch to digital cable and terrestrial television has taken longer. See also Digital terrestrial television. Not all countries are compatible within each standard DVB/T, ATSC(North America), DMB (China), ISDB(Incompatible Japan and South America variations). Countries that have adopted Digital Terrestrial recently may have a single MPEG4 based system for SD and HD. Countries with more established Digital Terrestrial may use MPEG2 for SD and MPEG4 for HD. There are also variations in Middleware used. For example Ireland, UK and Italy are all DVB/T region. But UK uses "MPEG2 + MHEG5 + DVB-T" for SD and "MPEG4 + MHEG5 + DVB-T2" for HDTV. Ireland uses "MPEG4 + MHEG5 + DVB-T" for SD and HD. Italy uses MHP rather than MHEG5 Middleware. But MPEG4 receivers all have MPEG2 codec and DVB-T2 receivers all have DVB-T tuner compatibility, so UK HD system works on UK SD system and Irish SD/HD system, but Irish SD/HD system only on UK SD system. Digital Cable Broadcast tends to be DVB-C or very similar QAM in almost all countries. Broadband on Cable is mostly DOCSIS which is DVB-C on the Download path. This is important when buying TV or set-box online rather than from a local retailer who would normally only stock the compatible system. Incompatible Retail products is a severe problem in emerging Retail Digital markets where neighbouring Country has an older standard and dominates the Retail Trade, such as UK Freeview (rather than compatible "Freeview HD") product in Ireland. Important DVB/T standards are UK D-book for UK Freeview and Nordig 2.2 for Scandinavia and Ireland. Ireland deviates from Nordig by using UK profile MHEG5 middleware rather than MHP. DTT broadcasti
