With the advent of popular broadcast television, producers realized they needed more than live television programming. By turning to film-originated material, they would have access to the wealth of films made for the cinema in addition to recorded television programming on film that could be aired at different times. However, the difference in frame rates between film (generally 24 frames/s) and television (30 or 25 frames/s) meant that simply playing a film into a television camera would result in flickering when the film frame was changed in mid-field of the TV frame.

1. SYSTEM AND METHOD FOR INTELLIGENT FRAME RATE
CONVERSION AND REVERSE TELECINE
Solution: An…redacted…that monitors the synchronization of the mechanical
film motion and the electronic video signal, and uses…redacted…from the
results of asynchronous frame rates not in perfect registration and ready to be
photographed. The invention maintains a…redacted…to measure the results
of a frame rate not in perfect registration and ready to be photographed and a
…redacted…of frame rates not in perfect registration that updates
autonomously in real time. The invention autonomously monitors
synchronization of the mechanical film motion and the electronic video signal
in response to ongoing results.
Problem: It is known that producers realized they needed more than live
television programming. By turning to film-originated material, they would
have access to the wealth of films made for the cinema in addition to recorded
television programming on film. However, the difference in frame rates
between film (generally 24 frames/s) and television (30 or 25 frames/s) meant
that simply playing a film into a television camera would result in flickering
