Frame Sync and Format Conversion

The switcher has multiple input frame synchronizer / format converter (FSFC) and input de-interlacers that can be used to convert video input signals to the format that the switcher is operating in, as well as correct mistimed, or drifting, video input signal. The frame synchronizers cannot completely correct badly formatted video, mistimed switches, signal drops, or similar issues.

Carbonite Black+ has 11 additional output format converters that can be used to convert the output video signal from the video format that the switcher is operating in to another format required by a downstream device.

Each FSFC channel maintains a separate setting for different video formats. This lets you change between video formats without losing FSFC channel configurations.

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 strip embedded audio data from the video signal. Ensure that no FSFC channels are assigned to any input or bus you are using with external audio mode.
  • In the standard mode on Carbonite Black, the FSFCs are fixed to the first 6 input BNCs.
  • The output format converters in the Carbonite Black+ frame are only available on output BNCs 11 to 22.
  • In the Standard switcher mode, the switcher cannot frame sync a 1080pSF video format on input BNC 1. All other inputs work correctly.
  • 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.
