With the DTA-2174B, DekTec’s popular DTA-2174 quad 3G-SDI card has an impressive successor. Its attractive price (€725 list!), lower latency and 12G-SDI support on port 1, make this card even more attractive for developers of video production and distribution equipment than its predecessor. All ports support DVB-ASI, allowing mixed compressed/uncompressed applications such as a 4K encoder with 12G-SDI input and ASI output, or a 4K decoder with ASI input and 12G-SDI output.

DekTec Matrix API^® 2.0 enables you to create custom applications for the DTA-2174B. Convenient Matrix-API features include directly inserting or extracting audio/video samples or ANC data, pixel format conversion and video scaling.

A block diagram showing the standard firmware loaded on the DTA-2174B is shown in the figure below. This firmware features four independent ports, each configurable to operate as ASI or SD/HD/3G-SDI input or output. Each port can also act as a double-buffered copy of another port to make multiple copies of the same output signal. Ports configured as output can be synchronized to the bi-/tri-level genlock input port.

A second firmware variant is intended for applications that require a 4K input or output in the form of a 4x 3G-SDI quad-link or a single-link 12G-SDI interface.

A third firmware variant targets 4K encoding/decoding applications with uncompressed input or output over ASI or a scaled down copy of the 4K content for monitoring purposes.

The DTA-2174B is the second member of DekTec's new range of SDI/ASI interface adapters for PCIe. These cards provide different numbers of bidirectional ports, at very competitive list prices. Even better prices are available if you are going to integrate these cards in your product. Please contact DekTec for a quotation with our inviting terms.
