Paloma TV tuner ()
three video sources – TV tuner, S-VHS, FBAS
the tuner supports only PAL B/G or PAL I, it does not support SECAM and NTSC
the videodecoder supports all standards, so it would be possible to use SECAM or NTSC through the S-VHS or Composite input (using a VCR as external tuner),the software (PalomaTV) is written PAL only
