The good news is they have finally found a way for tightwad studios to support upgrading to digital projection in theaters:

The digital projection guidelines, published in July by a consortium of Hollywood studios called the Digital Cinema Initiatives, say every five-minute chunk of video must contain a 35-bit “forensic marker” specifying the date, time and location at which the movie is shown. The guidelines don’t say how to get that information into the movie, but they require it to be “visually transparent to the critical viewer” and “inaudible in critical listening” tests.

The bad news is that the studios will never be able to justify the upgrades once they discover that steganography won’t stem the flood of piracy.

Let’s hope they upgrade all our theaters before they notice.
