XVP-3901-FS Frame Sync

The XVP-3901-FS is a highly integrated, 3G/HD/SD frame synchronizer/aspect ratio converter and optional video/audio signal processor, which is designed to synchronize and process HD and SD signals for 3G/HD/SD hybrid plants. It is identical to the XVP-3901 except that it does not have the up/down/crossconversion capabilities. It features a dual 3Gb/HD/SD input selector and provides multiple outputs. Although not up/down/crossconverting the input signal, the –FS model can still perform ARC control on SD signals, useful when converting 16:9 SD signals to 4:3 SD signals and vice-versa.


  • Frame synchronizer and aspect ratio converter (50/59.94 Hz)
  • Offers a multirate 3G/HD/SD input and outputs

  • Processes and converts ancillary data such as CC (CEA-608/CEA-708), timecode and teletext/OP-47
  • Inserts V-Chip and CGMS in XDS of CC (CEA-608)
  • Optional SFP optical plug-in cartridges to select between fiber and BNC inputs and output both electrical and optical signals simultaneously
