The DTA-2174B features four send/receive channels consisting of cable equalizer/driver, Matrix API logic and high-performance DMA controller. Some typical configurations are shown below.
Please refer to the Firmware Variants application note (see "Documentation pane on the left) for an in-depth description of the various configuration options.
Four independent 3G-SDI/ASI channels
Each channel can be configured (i) as input or output, and (ii) as ASI or SDI (SD, HD or 3G).
Quad-link 4K input or output
In these configurations a single 4K stream is sent to or received from the software. The firmware converts the 4K signal to/from a SMPTE 425-5 quad-link signal.
12G-SDI with ASI/SDI side channel
A main 12G-SDI input or output channel with a "side channel" that can be used independently for e.g. downscaled SDI output (up to 3G-SDI), or an ASI input or output. If the side channel is an output, it can be triply-buffered on ports 2, 3 and 4.
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.
DekTec Matrix API® 2.0 supports the DTA-2174B and all products listed below. Applications designed for one of these cards will run virtually unaltered on any of the other cards.
DTA-2172 – Dual 3G-SDI/ASI ports for PCIe
For applications that require two ports. No support for 12G-SDI.
DTA-2175 – HD-SDI/ASI in+out with relay for PCIe
Single HD-SDI/ASI input+output card with failover relay for creating redundant configurations.
DTA-2178 – Eight 12G-SDI/ASI ports for PCIe
Two times the DTA-2174B on a single low-profile PCIe card. On top of that, each port supports 12G-SDI input, with 4K to 2K scaling.
DTB-UBNC-BNC – BNC to micro-BNC conversion cable (25cm)
Short conversion cable for connecting cables with regular BNC connectors to the
micro-BNC connectors of the DTA-2178.
TLG-117 – Micro-BNC circular nut driver
Handy tool for loosening and tightening micro-BNC nuts as required for swapping full-height and low-profile PCIe brackets.
