  • Two independent software controllable bi-directional BNC ports, operable in ASI, SD-SDI or HD-SDI mode, with individual status LEDs.
  • Analogue genlock input port accepts bi- and tri-level synchronization signals.
  • Full-frame capture and play-out, but capturing a 1/4 or 1/16 hardware scaled resolution is also possible.


  • General purpose HD-SDI processor, recorder and player.
  • Video encoding and transcoding.
  • Key and fill generators.

DekTec Matrix API

  • Organizes incoming HD-SDI data in a matrix of frame buffers, so that frames can be accessed as a function of port number and time.
  • Synchronization of multiple input streams is straightforward: Frames with the same arrival time are stored in the same column.
  • Read or write to individual lines, HANC, VANC or full frame.
  • Access functions for embedding or de-embedding audio or other ANC data.
  • Supports all 16-audio channels.
  • Integrated and fully compatible with DTAPI.
