Closed Captions

The following FAB solutions can be used for CEA-608/708 closed captions:

  • Insertion into SDI with FAB PCIe Card
  • Export of closed captions to .SCC file

1. Insertion into SDI with FAB PCIe Card

Closed captions can be inserted in SD 625i50 video in VBI line 22 or in VBI line 18 or in VANC by using FAB Subtitler BCAST/XCD with the FAB PCIe Card. For SD 525i59.97 closed captions can be inserted in VBI line 21 or in VANC. For HD-SDI signals closed captions are inserted in VANC as native CEA-708 and also as CEA-608 tunneled in CEA-708.

2. Export of closed captions to .SCC file

FAB Subtitler STD/PRO/LIVE/MPEG can open subtitle files in many different formats and convert them to a .SCC file. Automatic conversion of subtitle files to SCC files using a watchfolder is available in FAB Subtitler PRO/LIVE. A REST interface for external control is available in FAB Subtitler MPEG.
