Data Compression in Mechanical Music Media
By Michael Woolf

There's a nice parallel in a system used for some early home movies.
The Pathe Bebe projector pulls its 9.5 mm film, with the sprocket holes
in the middle (yes, between frames), from a cassette and when it gets
to a still title frame a notch in the edge of the film engages a
cam-controlled mechanism that throws the projector into neutral and
freezes.  When there are a lot of words to be read, several notches
advance the film one frame at a time.  True Gallic ingenuity.
