DTA-2154 Features

  • Each port can be configured from software as input or output, and as ASI, SD-SDI or HD-SDI, in any combination
  • Hardware separates HANC, VANC, video with simultaneous access to full frames
  • On-board 1/4 or 1/16 video scaling
  • Bi-level and tri-level genlock input port, or digital genlock through port 1
  • Two RS-422 ports for connection to a deck
  • PCI Express x4 gen3 for high performance
  • Free drivers and SDK (DTAPI with Matrix API) for 32- and 64-bit Windows and Linux

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
  • Functions for embedding or de-embedding audio or other ANC data
  • All 16 audio channels can be read/written
  • Integrated and fully compatible with DTAPI

DTA-2154 Applications

  • General purpose processing of a mix of HD-SDI and/or ASI signals
  • Live production mixer and effect generators
  • HD-SDI monitoring, recording and/or play-out
  • Video encoding or transcoding

PC Requirements

  • Core i5 or i7, or equivalent AMD
  • 1GB free RAM minimum
