Separate telecine transfers for each projector type seems pretty
unlikely; we're already
trying to avoid multiple transfers as it is. My guess is that
digital projectors would have
a selectable input matrix to make them emulate a chosen phosphor
type. If the digital
projectors have a wide enough color gammut, it won't be a problem to
phosphor was used as a reference for the telecine transfer.
Even better, the metadata standards now taking shape for DTV would
handle this process.
There are metadata types that define the colorimetry of the video
material (i.e. 709,
SMPTE 170, SMPTE 240). When standards are in common use, all of our
matching problems will go away (insert big laugh here).
