FTTRM's full purpose is unknown, but it is likely DRM-related. It is used by the Bluray application (BdmvPlayerCore, BdvdPlayerCore, UHDBdPlayerCore) via /dev/fttrm. There are only two known commands. RM stands for Rights Management and FT may stand for FilmTrack or Film and Television Tracking. See [https://info.filmtrack.com/the-critical-role-of-security-in-entertainment-rights-management].
