Wikipedia Wrote:The SBTVD standard (based on ISDB-T) was adopted and launched in 2 November 2007. In 2007, only greater São Paulo metropolitan area can receive the signal. Belo Horizonte and Rio de Janeiro began to receive free-to-air digital signal in April 7 and April 8, 2008, respectively[26]. Government estimated 7 years for complete signal expansion for all over the territory. The analog television is set to be shut down in 2016, but it can be delayed if needed.
The interactive platform called Ginga [27] consists entirely on free software and received highly publicity being considered the main appeal for the change. The government promised WiMax as return channel for the system, set to be implanted in the next years. [28]
All 5 major TV networks (Band, Rede Globo, Rede Record, RedeTV! and SBT) broadcasts in HDTV signal (1080i), SDTV 480i and 1seg as well.
On the upside, the 1seg tuner for the PSP would probably work. Japanese PSP required.
I have read in the past that some manufacturers make ISDB-T capable devices that pretend to DVB-T from a drivers perspective. Its possible these would work in Brazil with GB-PVR. There is no way to know for sure unless someone tries it though.
