FAB SDI PCIe Card FT-HT 14 is a PCI Express card developed by FAB which can be used for insertion of subtitles into SD/HD/3G-SDI and for reading of VBI/VANC data from the Main and Aux SD/HD/3G-SDI input.

The card has a Main SD/HD/3G-SDI input which is passed to the SD/HD/3G-SDI output and is protected by a bypass relay which switches to bypass during a power failure. The card also switches to bypass when the FAB software is not working properly or is not started. The additional Aux SD/HD/3G-SDI input can be used to connect a second SDI signal to read timecode or teletext.

The card can be installed into a low profile and high profile PCI Express x1 slot. Drivers for Windows are available and the firmware update can be run from Windows when it may become necessary to update the card.

The card has been tested with HPE ProLiant DL360Gen10 and DL380Gen10 servers. Compatibility with other PCs and servers is not guaranteed.

The card can be used for:

Video path security

  • The FT-HT 14 card is designed in a way that it has a bypass relay for SDI so that in case of failure of the server hardware or power loss the SDI switches to bypass.
  • The switching of the bypass relay always occurs in the VANC part of the SDI signal so that nothing is visible in the picture when the bypass relay switches from/to bypass. This means that even when switching the server on or off or rebooting it (for example after installing Windows Updates) there will be no visible disturbance in the video/picture.
