DekTec DTA-2178-SY-SXP 8x 12G-SDI/ASI ports with StreamXpress, StreamXpert and SdEye

This includes SteamXpress , StreamXpert and SdEye

Eight 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 12G to 3G, enabling monitoring eight uncompressed 4K streams.

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 multi viewers;
    • 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 1 does not support 12G- or 6G-SDI output.

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.

 
 

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.
