DTA-2175

HD-SDI/ASI Input and Output with Relay Bypass for PCIe

A general-purpose HD-SDI input and output, both ASI capable. A relay automatically connects input port to output port upon software- or hardware failures, enabling highly-available system configurations without requiring a failover switch.

Features

General-purpose input and output port that can be independently programmed to operate in HD-SDI, SD-SDI or DVB-ASI mode.

Relay automatically connects input to output upon application crash or PC power failure.

DekTec Matrix API® 2.0 provides convenient access to video, audio and ANC-data.

Applications

Low-latency extraction and/or insertion of video-, audio- or ANC data, e.g. logo/subtitle inserter, audio embedder, etc.

HD-SDI (or ASI) playout and/or capture;

HD-SDI-in, ASI-out software encoder.

Analyze and/or monitor SDI with SdEye;

Analyze Transport Streams with StreamXpert.

Block Diagram

SDI and ASI input flows from port 1 through equalizer, deserializer, processing (encoding in a format suitable for transmission to PC) and DekTec's highly optimized DMA controller. The output flow to port 2 is very similar, but in the other direction.

If the PC power fails, or the watchdog times out, the relay falls back to its inactive position, connecting the input directly to the output.
