Ancillary Data
Ancillary data is information such as closed captioning or embedded audio that is included in the non-active video portions of the video signal. These portions include the Horizontal Ancillary Data Space (HANC) and Vertical Ancillary Data Space (VANC).
The switcher can be configured to strip or pass this data from the video output.
Note: Frame Converters and Synchronizers strip embedded audio data from the video signal.
The following restrictions apply to ancillary data being included in the output:
- MultiViewer outputs do not include any ancillary data.
- MiniME™ and MultiScreen outputs do not include any ancillary data unless an ME with ancillary data is re-entered onto the background bus.
- Setting ancillary data to be stripped.
