DTA-2172

Dual 3G-SDI/ASI ports for PCIe

Two general-purpose 3G-SDI bi-directional ports, both ASI capable, with genlock. This card enables you to create broadcast-grade applications for encoding, playout, insertion/extraction, etc. with an easy-to-use programming interface.
 

Features

• Two general-purpose ASI/SDI ports, each configurable from your application as input or output, and as ASI or SDI (SD/HD/3G-lvl-A/B).
• Synchronization of SDI outputs via analogue genlock input, accepting bi- and tri-level sync.
• DekTec Matrix API^® 2.0 for easy programmatic access to video, audio and ANC data. All SDI symbols in a frame can be read or written.

Applications

• Input/output of uncompressed or compressed streams for your software-defined solution:
  • Video encoding or decoding;
  • Video playout or recording;
  • Key- and fill generators;
  • Audio insertion or extraction;
  • Low-latency subtitle insertion.
• Stream station for generation, monitoring and analysis of ASI/SDI streams up to 3G-SDI.

The DTA-2172 features two transmit/receive channels, each consisting of a cable equalizer, ASI/SDI receiver, ASI/SDI transmitter, Matrix logic, high-performance DMA controller and PCIe interface.

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.
