Analog television
Digital terrestrial television was officially adopted by Brazil on 2 December 2007, using the ISDB-T International standard, a variant of the which uses H.264/MPEG-4 AVC for video compression and HE-AAC for audio compression, and support for mobile television using the 1seg standard. The government estimated that it would take seven years for DTT service to become available across the country; beginning with the greater São Paulo metropolitan, Belo Horizonte in early March 2008, and Rio de Janeiro in late May 2008. Analog television will be discontinued in phases until 2023. Major Brazilian networks broadcast their digital feeds in 1080i high-definition television.
