The PAL-M system is used in Brazil.  PAL-M has the following characteristics:

  1. 525 lines per frame, with luminance signal compatible with System M
     (the standard used in the United States and Japan).

  2. 30 frames per second.

  3. 2:1 interlace.

  4. Chrominance signal patterned after the European PAL system, but
     a color subcarrier very close to the US subcarrier (3,579,545 MHz)
     and no 25-Hz offset added in.

PAL-M is completely incompatible with European PAL.  Brazilian color
broadcasts could be received in black-and-white by an NTSC receiver and
vice versa, if the channel assignments were the same.
