Frame Sync and Format Conversion

Keep the following in mind:

Keep the following in mind when working with Frame Synchronizers and Format Converters:

  • If a video format not compatible with the currently defined conversion is used, the video image is frozen with the last successfully processed image frame.
  • FSFCs create a one-frame delay in the video output of the switcher for the video signal being converted.
  • FSFCs include dedicated SRC allowing for embedded audio to be preserved.
  • The FSFCs used in the switcher conform to the SMPTE ST 125:2013 standard. Some older equipment may not fully conform to the current standards and can send out-of-spec video to the switcher which can have unexpected results. Ensure that video coming into the switcher conforms to current standards, especially with regard to 480i video signals with variable blanking sizes.
