16.3. Locked Frame Rate Conversion
The decision to drop and repeat frames for triple-buffering is based on the status of the spare buffer. Because the input and output sides are not tightly synchronized, the behavior of the Frame Buffer II IP is not completely deterministic and can be affected by the burstiness of the data in the video system. This may cause undesirable glitches or jerky motion in the video output, especially if the data path contains more than one triple buffer.
By controlling the dropping or repeating behavior, the IP keeps the input and output synchronized. To control the dropping or repeating behavior, you must select triple-buffering mode and turn on Support for locked frame rate conversion or Locked rate support parameters.
