DTA-2178
Octal 12G-SDI/ASI Ports for PCIe
High density, attractive price. Eight ports that can do SD to 3G, and ASI, in any mix. Ports 1 and 5 can receive or transmit full 12G-SDI to stream two times 2160p50/60. Each port can scale 4K to 2K, enabling the monitoring of eight 12G-SDI signals.
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.
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 multiviewer systems
- Multi-channel playout
- Stream processors or transcoders
- Compliance recorders
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 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.
