Just a warning: as the person writing this blog no longer has a tube TV at home, since the analog signal is broadcast in 4:3 in Brazil, black bands are also added to the sides of the screen to avoid distortions. In Portugal we broadcast in 4:3 format as private channels (SIC and TVI) recently changed to 16:9 in October 2015. For many years, all textual content of HD broadcasts needed to be located within the 4x3 safe area, which ensures that all televisions have access to the textual information, the station logo and other channels were in the "middle of the screen" in digital broadcasting. With the change, starting March 20, 2016, it will be moved to the bottom right corner to become larger, it will no longer be necessary to respect this limitation. With this, the logo will return to the corner of the screen, as it was at the beginning of HD broadcasts. This change will happen on other analogue channels on other broadcasters in the future.

As anticipated here in the post, this morning, Globo changed the position of the broadcaster's logo to the 16:9 area during the F1 broadcast.
