16.3.1. Converting Frame Rates

You can enable or disable locked frame rate conversion at runtime.
  1. Turn on Locked Rate Support in the GUI, which adds hardware that supports locked frame rate conversion.
  2. Set register 10 with the current input rate and register 11 with the current output rate.
    For more detail, refer to Frame Buffer II Control Registers Map table.

    For example:

    • For a 60Hz frame rate, set a value of 60.
    • To convert 60 Hz to 50 Hz, set register 10 to 60 and register 11 to 50.
    • To convert from SDI 59.94 to 60, set register 10 to 5994 and register 11 to 6000.
  3. Enable or disable locked frame rate conversion with the Locked Mode Enable register (register 9).
