DTA-2174B
Quad 3G-SDI/ASI Ports (1x12G) for PCIe
The industry workhorse for interfacing uncompressed video to PCs, attractively priced. Perfect for 4K encoders/decoders thanks to 12G and quad-link 3G support. The card can be configured for a variety of other SDI/ASI-processing applications.
Features
Ports can be fully configured from software as a) 4x independent 3G-SDI/ASI, b) 1x 12G-SDI with ASI/SDI side channel, or c) quad-link 4K.
External synchronization of SDI outputs with analogue genlock port that accepts bi- and tri-level sync signals.
The smart architecture of the DTA-2174B enables a cost-effective hardware design, unrivaled by other cards in the market.
Applications
Software-based 4K decoder and/or encoder with 12G-SDI or quad-link 3G-SDI interfacing.
4K decoder with 12G-SDI and downscaled triply-buffered HD/3G-SDI monitoring output.
Multi-port SDI and/or ASI applications, e.g.:
- Live production mixers;
- Transport-stream multiplexers;
- SDI multi viewers;
- Multi-channel transcoding to/from IP.
Block Diagram
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.
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.
