Features
- Four fully independent ports, configurable from software as input or output, ASI or SDI, in SD/HD/3G or 4K multi-link (4x 3G-SDI).
- External synchronization of SDI outputs via port 1 (digital genlock), or with analogue genlock port accepting bi- and tri-level sync.
- Create your own applications for processing SDI (up to 3G) and/or ASI signals with the easy-to-use DekTec Matrix API® 2.0.
Applications
-
General purpose SDI and ASI I/O, e.g. for:
- Video encoding and transcoding;
- Live production mixers, effect generators;
- Teletext-, subtitle inserters.
- ASI/SDI stream station for analysis, monitoring and generation of all SDI rates up to 3G-SDI.
- Recording and playing back 4K content with standard PC hardware, using VF-REC with JPEG-2000 compression option.
Block Diagram
The DTA-2174 features four independent transmit/receive channels, each consisting of a cable equalizer, ASI/SDI receiver, ASI/SDI transmitter, matrix logic, a high-performance DMA controller and a PCIe interface.
DekTec Matrix API® 2.0
The Matrix-API framework decodes incoming SDI data into pixels (in a programmable format), audio samples and ANC data structures. When a new frame has been received, the framework calls a user-supplied "frame-processor callback" for processing of the data. The user callback can create output video, audio and ANC data. which is encoded by the framework into SDI frames.
Synchronization of multiple input streams is straightforward: The video/audio/anc data of all SDI frames supplied to the callback function have the same arrival time by definition. Past frames can be accessed by an integer frame index. The framework ensures that if frames from different input ports have the same frame index, they have entered the system at the same time instance.

DTA-2174 Bird's Eye View
The DTA-2174 is available in a standard configuration with one cooling fan, and in a special OEM version without fan (DTA-2174-NF), which requires sufficient airflow in the PC.
