The digital TV transition (also called the digital switchover (DSO) or analog switchoff (ASO), sometimes analog sunset) is the process in which analog television broadcasting is converted to and replaced by digital television. This primarily involves both TV stations and over-the-air viewers; however it also involves content providers like TV networks, and cable TV conversion to digital cable.
Digital TV transition in Brazil began free-to-air HD digital transmissions, after a period of test broadcasts, on Sunday, December 2, 2007 in São Paulo, expanding in January 2008 to Brasília, Rio de Janeiro, and Belo Horizonte. Digital broadcasts will be phased into the other 23 state capitals by the end of 2009, and to the remaining cities by December 31, 2013. Analogue and digital simulcasts will continue until Wednesday, June 29, 2016, when analogue will be discontinued. The main broadcasters (Globo, Record, Band, SBT and RedeTV!) are simulcasting in analogue and digital broadcast, in standard definition and 1080i high definition.
