Interface

8x 12G-SDI/ASI in/out
1x genlock in

Product Features

  • Eight independently configurable ASI/SDI ports on a single-slot low-profile PCIe card!
  • Ideal general-purpose card for interfacing uncompressed and compressed digital video streams to PCs, from ASI to 4K UHD.
  • External synchronization of SDI outputs with analogue genlock port that accepts bi- and tri-level sync signals.

Firmware Variants

The DTA-2178 has three firmware variants, described in detail in application note DT-AN-2178-1. An overview of the three variants is shown below.


Variant 1 - Eight 3G-SDI/ASI channels with 12G-SDI to 3G scaling

Each channel can be configured independently as input or output, as ASI or SDI (SD, HD or 3G), or as copy of another port in a group of 4 ports. 12G-SDI input is supported by scaling to 3G in the 4K-to-2K block. Similarly, 6G-SDI can be scaled to HD.
*Variant 1 does not support 12G- or 6G-SDI output.



Variant 2 - Dual 4K channels over 12G-SDI or quad link

This variant supports two full 4K UHD streams: 2x 4K input, 2x 4K output, or 4K input + 4K output. Each 4K stream can be carried over 12G-SDI or over SMPTE 425-5 quad-link 3G.



Variant 3 - Dual 12G-SDI with ASI/SDI side channel

Two 12G-SDI input or output channels with \"side channels\" that can be used for downscaled SDI output (up to 3G-SDI, downscaling to be handled by the software), or an independent ASI or SDI input or output. If the side channel is an output, it can be triply-buffered on ports 2/3/4 or 6/7/8.

Applications

  • Software-based UHD decoder and/or encoder with 12G-SDI or quad-link 3G-SDI interfacing.
  • Multi-port SDI and/or ASI applications, e.g.:
  • Live production mixers
  • Transport-stream multiplexers
  • SDI and ASI multi viewers
  • Multi-channel playout
  • Stream processors or transcoders
  • Compliance recorders.

Supported Software

  • StreamXpress TS / SDI playback software
  • StreamXpert v2 real-time TS analysis, decoding, recording software
  • StreamXpert Lite real time TS decoding, recording software
  • SdEye SDI Analyzer Software
  • VF-Rec multifunction TS / SDI recording software * A separately sold software license is required
