Option “P” Biphase to Time Code Converter Page 5 Functional Description 1.1 Overview The “Option P” for a RUBIDIUM Time Code Module (AT, DT, HT or XT) has been developed for “film and time code” applications. This special RUBIDIUM Module accepts biphase signals at its GPI inputs. These pulses will be converted to a time (HH:MM:SS:FF), to a film frame counter and to a footage counter.

Option “P” Biphase to Time Code Converter Page 7 Basic set-up of the time code generator: The following adjustment will be important for a biphase to time conversion: Frame Rate: Select the frame rate of the time code: 24/25/30df/30. For a frame accurate biphase to time code conversion this frame rate has to correspond to the number of film frames per second.

Instead of changing the connection you can swap A with B (“R”...

Two inputs have been reserved for the biphase signals; two inputs may be used for external push buttons: GPI_1 Biphase Signal A (“R”)
Option “P” Biphase to Time Code Converter Page 15 Applications In all applications it is necessary to correctly select the parameters: Pulses per frame, Frames per foot. Further it is assumed that time code and film run 1:1, i.e. film frame frequency during PLAY corresponds to the time code frequency.

Having Lock auto count activated the ‘Lock Delay’ parameter has to be noticed. This value represents a time period (in units of time code frames) during which the system should reach a stable state (Stop →...

Option “P” Biphase to Time Code Converter 3.4 Two Projectors Connected via a Switching Box The “Plura BIPHASE SWITCHER” box enables to connect two biphase sources (film projectors). The box automatically detects the source and feeds these signals to the RUBIDIUM module, which still counts the pulses from one projector only.
